\noindent Source or Image Name: Mercury

\noindent Alternate Names:

\noindent Description of Observation: (e.g., date of observation,
telescope(s) used, frequencies, polarization type, resolution,
deconvolution method)

     Observations were made on Feb. 2, 1988 in the B-array at 2 cm.
The map was self-calibrated, and deconvolved using the Maximum Entropy Method.
The Clean Restoring beam is 0.6 x 0.6 arcsec.

\vfill

\noindent Description of Image: (e.g., type of source, scientific reason
for observing, notable source features)


     This is a VLA image of Mercury at 2 cm in the B-Array. This map
represents the temperature distribution across the disk of the planet in
degrees Kelvin.  Note the two hot regions along the equator at the edges of
the disk.  These observations were the first to spatially resolve and map
these Hot longitudes.  These so called "hot poles" are a result of
Mercury's 3:2 spin-orbit resonance and its high eccentricity.
We have used these data as basis for devolpment and testing of theoretical
models for the thermal history and properties of Mercury's subsurface.
