解説（安達）/ Comment by Makoto Adachi
Given the very poor conditions this morning (the whole Southern African region is experiencing some cold weather due to a high pressure system SW of South Africa),the only reason I persevered was the dust activity that I had seen over Lunae Lacus and southern Chryse yesterday. I had to make do with IR.
The dust in southern Chryse appears to have expanded over that region,whilst being less intense,and also expanded southwards into eastern Valles Marineris.
Nilokeras looks a bit subdued and may be affected by the dust,and Niliacus Lacus also appears to be distorted.

Here is an image from this morning. Average seeing. A large dust cloud is obscuring part of Mare Acidalium and Chryse.

Lots of diffuse dust though no real dense centres i think; the aftermath of yesterday and the day before's dust.

Here's a batch of Mars images from August and September made with a new mono camera, ASI462MM which from now on replaces the 462MC. RGB images were obtained through a set of Meade interference filters until Sept 19, which was shot with a set of ZWO "new" RGB interference filters. These have higher throughput, better color balancing and apparently better optical quality than the Meades.
The NPH was large and bright on all dates and it looks like the brightness has gradually increased. I missed the storm activity in August due to telluric clouds, but Hellas was whitish bright on the morning limb on Aug 27. Seeing has continued to be poor, unfortunately.
