Started observing Mars in a bright sky at 19:30UT, very good seeing and very steady even at x300. Did the drawing over the next twenty minutes and very rapidly after that the seeing deteriorated to dreadful !!
Still managed to see the North polar cap which is very dull, Hellas above Syrtis Major was brighter than the NPC, as was Libya. Sinus Sibaeus was visible as a long dark elongation. No real detail at all just the major features. Mars is rotating to the quiet side now so I really do think that's it for Mars ........ maybe
The small image in the drawing is roughly the size Mars actually appeared.
8" F/6 Newtonian, x300

Seeing AII, deteriorating to AIII.
