一応晴れましたが、どこからか時折小雪の舞い飛んでくる寒い日でした。

Attached is an observation of Mars made on 18th February 2021 during which time there are now three new spacecraft actively exploring the planet!
Telescopically the planet is becoming challenging with an apparent diameter of 6.8".
None the less,there were a number of interesting features on show:
・The SPR seemed brighter tonight,although there was little in the way of fine details in the far south.
・The Hellas basin was rather bright- possibly filled the clouds. This can be made on the the prec. limb.
・Noachis was rather dull,although lighter than Pandorae Fretum to the north.
・Deucalionis Regio is still a brighter zone beterrn Pandorae Fretum and Sinus Sabaeus.
・Sinus Sabaeus was the darkest feature on the disk and showed the most structure.
・Erythraeum visible on the following side but some of this feature was faint and vague.
Interestingly there seemed to be brighter patches in Chryse?
・Niliacus Lacus present n the far north along with the bright NPC.
