See the PLANCK observing campaigns page here.
The gamma-ray level of this FSRQ has recently increased 10-fold (Atel #2795), and the 37 GHz flux has also been on the rise lately. Let's observe it quite frequently.
This Seyfert galaxy has some gamma-ray activity going on, and an mf-campaign has been launched. Let's monitor it till mid-September (at least) to see if anything happens at radio. Try to observe it once a day or so.
This BLO has been recently detected both by Fermi and MAGIC (Atel #2753). It is a radio source but we don't have any prior observations of it so let's get a few right now.
There have been several high energy detections of this source recently so let's observe it very frequently in Metsahovi, too (i.e. approximately once a day).
Metsähovi participates in a large multifrequency (radio, optical, gamma, TeV) campaign on Mark 421. The campaign will last an entire year (!), starting 8.12.2009 and ending 1.12.2010. The most important period will be during mid-December 2009 (that is, right now) to mid-June 2010, during which *daily* observations are requested -if at all possible. So, let's try to observe this source every day, and in any case always as soon as possible after a break (bad weather, VLBI etc).
Currently there is an ongoing large multiwavelength campaign (AGILE, RXTE, Ryle, RATAN, PairItel, Calar Alto, WSRT...) dedicated to Cygnus X-3 - Cyg X-3 is a highly variable and unpredictable source, so it would be great if we could get as much coverage in the upcoming days/weeks as possible. Maybe one observation per day for now is good, but in case of an outburst feel free to observe it more frequently. Diana will keep observers updated.
Fermi continues to record high activity in this source (Atel #2534).
The flux of this source has started to rise at RATAN, and they ask us to monitor it at Metsähovi, too.
OJ287 has been very bright lately, and for a while it was brighter than ever at 37 GHz so let's keep an eye on it.
This source was observed to have bright IR-flux (Atel #1874). In addition, it has been regularly detected by the Fermi LAT since August 2008 (Atel #1877). It is being monitored by a group of telescopes of which Metsähovi is one, so we should observe it regularly (once a week or so).
0420 is bright at optical and radio (Atel #2395) and also gamma (Atel #2402).
3C 273 is flaring in gamma rays (Atel #2376\ ) and both Fermi and INTEGRAL are following it. The INTEGRAL observations will go on until the end\ of February. Multiwavelength observations are requested.
Metsähovi participates in a large multifrequency (radio, optical, gamma, TeV)
campaign on Mark 421. The campaign will last an entire year (!), starting 8.12.2009
and ending 1.12.2010. The most important period will be during mid-December 2009
(that is, right now) to mid-June 2010, during which *daily* observations
are requested -if at all possible. So, let's try to observe this source every day,
and in any case always as soon as possible after a break (bad weather, VLBI etc).
Mf follow-up observations are requested for a Chandra campaign on Cyg X-3. Observe
it a couple of times on the following days:
2010-01-25
2010-02-22
2010-03-01
2010-03-08.
AGILE and Fermi have detected strong gamma-ray flares in this source in mid-December (Atel #2348, Atel #2349). A flare can also be seen in latest our 37 GHz data. Let's keep an eye on the source, it might continue going up at radio, too.
3C 66A is in an active optical state. Observe it frequently also at Metsähovi.
Fermi LAT and INTEGRAL have detected increasing activity of this source. It is also brightening at optical and IR. Multifrequency observations of this source are requested. (Atel #2154).
The VERITAS Collaboration reports the discovery of very high energy gamma-ray emission from the high-frequency-peaked BL Lac object 1ES 0502+675. The redshift is z = 0.341, which makes this the most distant BL Lac with a secure redshift detected at VHE (Atel #2301). There are a couple of proper detections of this source at 37 GHz so it's a good candidate also for us.
0716 is going through a very large mm/radio flare (for example,
Atel #2342).
Unfortunately the weather has been very bad lately here at Metsähovi, so at the moment the
only indication of the beginning of this mstrong flare comes from a single measurement at
the end of November. We need more measurements as soon as possible! If the flare
is as spectacular as it currently seems, we should observe the source daily. In addition to
this, a global mf-campaign will take place Dec 11 - 15
(see details here),
during which a few points daily would be good.
The mf campaign also targets S40954+65 (as a secondary target), and as it is
close to 0716, take a couple of measurements per day of it, too.
The H.E.S.S. and Fermi collaborations report the discovery of very-high energy and high-energy gamma-ray emission from this high energy peaked BL Lac object, located at a redshift of z=0.287, one of the furthest VHE blazars with a well-determined redshift today (Atel #2293). It has not so far been detected at Metsähovi but let's try again a few times.
Both VERITAS and Fermi recently detected gamma-ray emission from this source (Atel #2272). It's a BLO, fairly faint at 37 GHz, but our latest observation is from 44/07 so let's try to observe it again soon.
Fermi has recently detected a gamma-ray flare in this source. A very large gamma-ray flare was reported in September (Atel #2200). Multifrequency observations are requested.
This source has recently brightened a lot at optical wavelengths (Atel #2222), and it is still going up also at 37 GHz. Remember to observe it regularly.
Swift/VERITAS campaign during weeks 42 and 43. Simultaneous observations are requested.
The Swift observing times are:
10-13-2009: 7:20 UT to 8:40 UT
10-14-2009: 7:20 UT to 9:40 UT
10-21-2009: 6:50 UT to 9:10 UT
10-22-2009: 6:40 UT to 9:10 UT
10-23-2009: 6:40 UT to 9:00 UT
10-24-2009: 6:40 UT to 9:00 UT
10-25-2009: 6:30 UT to 9:00 UT
10-26-2009: 6:50 UT to 9:00 UT
10-27-2009: 7:50 UT to 8:50 UT
There will be an extensive multifrequency campaign on this source between 20 July 2009 and 31 August 2009, including Fermi and possibly also TeV observations. Good coverage is required at radio frequencies so observe it daily if at all possible.
XMM will observe this source in September, with other instruments (campaign site). Remember to observe it frequently also here, particularly during the most intensive campaign period 8-14.9!
Fermi LAT detected increasing activity of this source on August 23. Our most recent observation is from end of July, so we need a few new measurements soon. (Atel #2175).
4C 38.41 is flaring at gamma-rays, take a look at it a couple of times a week to check out the radio behaviour, and if the flux is rising, observe it more frequently.
Fermi LAT has detected source 0805-077 in a flaring state on May 14 (Atel #2048). Observe the source frequently.
Fermi LAT has detected very rapid flaring activity from the source NRAO190 on May 15 (Atel #2049). Observe this source frequently.
A new possible gamma-ray source 4C31.03 was detected by Fermi LAT on May 20 (Atel #2054). This source has not previously been detected by Fermi or EGRET. Its historical radio flux is about 0.5 Jy at 37 GHz and it should be detectable in good observing conditions. Observe this source also frequently.
A recent radio spectrum of the source indicates that it is in an active / flaring state in the radio regime. Therefore we should continue to observe the source frequently.
The Fermi LAT team is organizing a multifrequency campaign on this source, starting on March 26, 2009 and lasting for 3 months. More information can be found here. Remember to observe the source frequently during the campaign.
Fermi LAT has detected this source to be flaring in gamma-rays since April 20 (Atel #2026). Therefore multifrequency observations are requested and we should also be observing the source more frequently.
Fermi LAT has detected this source in high gamma-ray state on April 16 (Atel #2021). The gamma-ray flux is now 10 times more than the average flux from the 6 months of LAT operations. Therefore it is important to monitor this source frequently at least as long as it is in high gamma-ray state.
This source was detected by Fermi LAT in a high gamma-ray state on March 20, 2009 (Atel #1986). It was observed by SWIFT on March 26 and 27 to be in high x-ray state as well (Atel #1991) . Therefore multifrequency observations of this source are requested. This source has now been added to our sourcelist and should be observed frequently at least as long as it is in the high gamma-ray state.
This list shows sources detected to be in a flaring state by the Fermi Gamma-Ray Space Telescope and which are included in our observing list. It is important to get radio observations daily at least 2 weeks after the detection and remember to observe the sources frequently also longer time, especially if the sources seem to be flaring in radio too.

GLAST (Fermi Gamma-Ray Space Telescope) Large Area Telescope AGN science group is organizing an intensive multifrequency campaign on this source. Satellites Swift and RXTE have been observing the source until Sep 9, but radio and optical bands should be observing until the end of September. Remember to observe this source daily until the end of September!
This source shows exceptionally fast apparent speed in the radio jet which could be seen as fast variations in our flux curve. Therefore we would like this source to be observed at least twice a day for 2-3 weeks to see if there are very fast variations in the source's flux.
This X-ray binary will be observed with the Spitzer satellite on August 22, 2008 at:
04:11:59.6 - 07:24:52.7 UT and

Whipple telescope will be making TeV observations of 1ES2344+514, 1ES1959+650, Markarian 421, H 1426+428 and Markarian 501 during the autumn 2007 and next winter. The observations will be mostly done in the following time intervals.
1ES2344+514 : October 2007 - January 2008XMM-Newton will observe this source during three observing sessions as a part of a WEBT campaign. Next pointing will be on January 8, 2008 from 14.56 UT until 22.34 UT.
Previous pointings:The pointing in December was on December 5 at 15.01 UT and ending at 20.48 UT. The first one was in July 2007, starting on July 10 at 22:48 UT and ending on July 11 at 04:22 UT. Observe this source frequently during the session and also around it, starting now!
More information is available on the WEBT campaign webpage.
Idea is to start to observe OJ287 regularly before the next predicted outburst on it. The predicted outbursts will occur either March 2006 and October 2007
(According to Mauri Valtonen) OR September 2006 and November 2007 (according to Aimo Sillanpää).
We should observe OJ287 at least once every week until March 2008, and more intensivily during the predicted time of the outbursts. The Tuorla team has already submitted VLBA observing application to cover time from spring 2005 up to 2008 with bimonthly observations at 5 frequencies. They will also submit applications to satellites, to observe the source during outbursts.
OJ287 is now at its highest optical state since 1984 so observe it also daily so that we can notice immediately if it starts to brighten also in radio. Notify others if you notice that its flux is rising.
AGILE has detected a new gamma-ray flare from this source. Please observe this source daily, preferably more than one data point each day.
Previous pointings:There will be a new WEBT campaign on this source to follow the post-outburst phase. XMM-Newton will observe the source on three following sessions:
June 24 -Jul 3, 2006
December 10-20, 2006
May 23-28, 2007
Exact time for XMM observations has been re-scheduled to May 31, starting at 8:56 UT and ending at 17:26 UT. Dense monitoring is wanted during the pointing and observations around the pointing are also needed.
The observing time has been postponed to Dec 18 and 19 due to strong solar flares which prevented XMM to observe the source on Dec 10-11 as was originally scheduled. New observation time is scheduled, starting on Dec 18 at 19.40 UT and ending on Dec 19 at 00.15. Dense monitoring is wanted during the pointing and observations around the pointing are also needed.
Exact time for XMM observations is July 2, starting at 21:07 UT.
Dense monitoring is wanted also before and after the pointing between times June 25 and July 9. We will observe this source at least daily during that period. There is Geo-VLBI session during the pointing so those who are observing before or after the Geo-session, Remember to observe this source!
Here is more information about the XMM pointing on July 2:
Target_Name 3C 454.3 RA 22:53:57.75 Dec

We will monitor this source frequently all times and more during the XMM pointings. Exact dates will be given later. The campaign manager is Claudia Raiteri and more information can be found on this campaign webpage.
The source was brightening in the optical in the beginning of November. Radio observations are also wanted so remember to observe this source every now and then and report if you get detections.

Suzaku will observe this source for three days between August 2-5. The observations will start on August 2 at 9.24 and end on August 5 at 5.50 UT. We have a GEO-VLBI session until the 3rd of August but remember to observe this source daily from now on and also after the GEO session.
Change of Suzaku observing time:
Suzaku will observe this source from March 15, 21.30 until March 16, 15.10 UT instead of March 7-9 2006 as was originally planned. Simultaneous observations are important and also observations before and after the campaign. Remember to observe this source at least once a day before and after the campaign.
3C279 is getting bright and INTEGRAL will be observing it on January 13th-20th.
Chandra will also probably be observing it on the week starting at January 16th.
Therefore it is important to observe this source every day when it is possible.

OJ 287 is currently bright (R~13.7). Thus the campaign of November 2-5 (see below) is extended starting from October 19 up to November 10, at least, depending on the brightness behaviour.
the second XMM pointing of OJ 287 has been scheduled:
start: November 03, 2005 at 20:59 UT
end: November 04, 2005 at 11:09 UT
Accordingly, the Part 2 of the WEBT intensive intranight campaign on OJ
287 will be carried out on November 2, 3, 4, and 5,
with particular focusing during the 51 ksec (~ 14 hours) of the XMM
pointing.
For more information, see the campaign webpage.
This source turned out very bright in optical on May 9 (2005) when Tom Balonek was observing it. It was also very bright in mm-region. It is still in active state in radio and it should be monitored frequently.

Suzaku will be observing the blazar 0836+714 during the week starting Nov. 13th (week 46). More detailed schedule will be given later. It is a unique source with a very hard X-ray spectrum and most likely will be a strong detection in the HXD detector. This blazar was detected as an EGRET source and is already on our list. It would be good to get simultaneous observations during this week.
We were asked to observe this source simultanously with Suzaku X-ray observations.
The source is a new high-z blazar discovered with the BAT on SWIFT.
A 100 ks Suzaku exposure has been scheduled on:
Start Nov. 4 10:00 (UT) Stop Nov. 6 12:00 (UT).
This source consists of two galaxies and it might be a buried AGN. It had an IR-flare and it would be interesting to find out if it has a radio-flare coming. We should observe this source now about once a week to find out if there will be a flare. It was a non-detection on February 7th. This source is not yet in our web-sourcelist, but contobs recognizes the source by name. The coordinates are 11:28:31.0 +58:33:41. In XEphem its symbol is a medium-sized blue dot.
This source has been observed with VLBA and GMVA after a major mm-flare, which occured early 2002. The next VLBA session will be on February 3, 2005. We have been asked to observe this source near that time.
This is an ENIGMA / WEBT campaign on source 0235+164. XMM data from 18.1.2004 has been reduced and analysed. Latest XMM pointing was on August 2nd, starting from 00:23:55 UT up to 04:00:35 UT. The campaign is still ongoing and the next XMM pointing is scheduled for January 28, 2005 from 14.42UT up to 19.22UT. The Effelsberg 100m radio telescope will observe the source from 15 to 21 UT. Contact person is Claudia Raiteri, see the WEBT collaboration site.
Here is a list of sources Elina Nieppola asked us to observe. They are HBLs and some of them might be faint. She has listed here the sources that might be detectable. These sources should be observed once in every two months
If the conditions are good, these sources should be detectable:
1ES0806+524
87GB02109+5130
B20906+31
MRK180
NPM1G+19.0510
S52051+74
If these sources happen to be in a bright phase, we could get a detection:
