久しぶりの晴れ間でしたがシーイングはメチャメチャでピント位置もさっぱり分からず、おまけに薄雲の通過も邪魔して、どうにもなりませんでした。

In reasonable seeing conditions.  The disk size is now only 8.3" so it is getting increasingly difficult to see fine details on the Martian disk.  There were however a number of points of interesT:
・The evening limb is very bright with white cloud activity.  The evening clouds extend into the south of the Hellas basin which is quite bright.
・In drawing 1 the Mare Tyrrhenum can be seen and is quite dark.
・Hellespontus was rather dark while the Yaonis Regio seems to be lighter.
・Syrtis Major was well seen,the northern part of the feature was bluish in colour no doubt due to white cloud activity.
・Streaks seen in Protonilus and Aeria,and Boreosyrtis
・Cassius and Umbra quite dark while the NPC can be seen with collar
・In Drawing 2 the ECB was very apparent and there were streaks in Eden while the edge of Acidalium can also be made out.
