Dear Mr.

I made an observation of Mars this morning. I noted a good
mount of detail over the Solis Lacus region as well as interesting cloud
phenomena. I welcome any comments on my observation.

The South Polar
Cap (SPC) appears brilliant (10/10) over the southern limb. Mare Australe appears as a dark (3/10) collar along the southern
border of the SPC. Mare Erythraeum (3-4/10) appears obscured by a very bright
(8/10) haze. An extremely bright (9/10) terminator projection
ars over the Argyre region (haze with possible
dust?). Aurorae Sinus appears dark (3/10) with a dark to dull (3-5/10) Agathodaemon (Coprates) extending
from it's following border (Tithonius Lacus appears to
be obscured by an extremely bright (9/10) haze). Bosporos
Gemmatus appears dark (3/10) extending between
Aurorae Sinus and Aonius Sinus (3/10). Solis Lacus
appears dark (3/10) and elongated in a NE-SW direction and connected to Mare
Erythraeum by a shaded (4/10) Nectar. Two projections are noted over the
southern border of Solis Lacus, namely Ambrosia (5/10) followed a thicker
Bathys (4/10). Thaumasia,
The
best of luck to you and your fellow observers.
