Metsähovi Radio Observatory observed the 4.1.2011 partial solar eclipse with its 13,7-meter radio telescope at a frequency of 37 GHz. Eight solar maps were made that show the Moon passing in front of the Sun from right to left.

Alternative "exposure" reveals radiation from the Moon's night side:

By essentially "overexposing" the solar maps, radiation emitted by the Moon can also be revealed. In the maps below, the Moon can be distinguished as a separate orange circle against the slightly darker background sky. One extra map is displayed here to show how the Moon completely leaves the "field of view" of the telescope.
