久しぶりに晴れたけど、シーイングは悪いです。
気圧配置から考えると悪くて当然なので晴れただけ
良しとしましょう。

Some might have read that I suspected a dustevent but after all the images processed (pfff...) there seems little evidence...it remains a strange bright patch on the limb,maybe there is still a small amount airborne or so but can't be seen against the planet. There seems a extention of the NPH in the Ismenius Lacus region,further on the southside of the morninglimb bright blue vapours or ice

I have attached Mars images from 13 December,taken under poor conditions.
There is little evidence of the NPC.
There are many arctic clouds,thick NPH remnants,a PM limb cloud over Edom and delicate hazes over Margaritifer.

Following the good seeing of 24 hours earlier, it was back to the usual rubbish. Downsized to preserve decency.
