解説（安達）/ Comment by Makoto Adachi
[Mark Lonsdale : [Canberra,Australia]
We had a clear night here with excellent seeing,and so I was able to make another observation of Mars.
Using powers of x375 and x600,I was able to see quite a number of details on the disk-
remarkable really given the planet now only subtends an apparent diameter of 5.0"!
Points of interest were the following:
・Brightening at the SPR- also some vague shadings nearby.
・Both Electris and Eridania were visible and brighter than the darker albedo features nearby.
・The Mare Cimmerium was the main feature on the disk- the region close to the prec limb was notably darker
and looked like a darker patch distinct form the rest of the region.
・Further north,it seemed to me that Trivium Charontis and Cerberus were fairly well defined.
Aksi darker markings in Chaos and Hyblaeus,although the shadings here were not as obvious as those of Trivium and Cerberus.
・Further dark marking near to Phlegra- could this be Propontis I?
・NPC bright and well defined,a darker band evident immediately south of the cap.

Mars on April 12th under fair seeing. NPC visible, even Olympus Mons is still visible.
No other weather phenomena recognizable.
