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 (25°C at night, 39°C 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):
