Hi All,
To second Steve, these sun spots are worth viewing even in the heat. 104F for
me around 12:30P in Chandler. The dark markings between the poles of the big
group are very interesting. I would describe the markings as a "twisting dark
river of magnetism". The big group is easy naked (filtered) eye.
I have added two more pics from today (7/20) to the bottom of this page...

Howdy all;
Well, it is a hot day in Phoenix to be observing the Sun, but there are some
excellent sunspots to see.
One in particular is just on the face of the sun and it is HUGE. There is a
large dark umbra and a much bigger penumbra on all sides. As usual, there are
two obvious north and south poles, but they are attached together with several
dark markings that run through the umbra. Fascinating! All this is at 175X in
my 7 inch Maksutov with a Baader filter. If you have a solar filter now would
be a fun time to break it out. There are several other spot groups to see, but
the view is dominated by the large group.
Take Care;
