Dear All,

 

In this hot summer, the seeing at night is still not too bad, although, it could be better if atmosphere would cool further down (25C at night, 39C during day is a bit too much). Please find attached here my 2 latest drawings, with northern hemisphere, and Solis Lacus surroundings still very pale and low contrast (I do think not as dark as in 2001, but my optics are getting dusty - I should have a new telescope very soon). I have updated my webpage (July-August observations):
