Mars on July 27, 2018
Mars and Olympus Mons
Mars is now at maximum size and the skies were unpredictably stable over the house
on the morning of July 27th. The global dust storm appears to be letting up a bit. Mare
Sirenum was dulled by the dust but could be seen. Most of the disk that was visible
showed the great orange-yellow deserts of Mars.  There appeared to be a dark section
"rift?" forming in the South Pole Cap (south is up in the drawing).  The highlight of the
night was seeing Olympus Mons sticking above the dust.  It is only during dust storms
that I can see the great volcanos of Mars directly through my telescope.
