It’s time to say goodbye to sunspot 2403! Tomorrow this large sunspot group will be right on the edge of the visible side of the Sun, and eventually will depart altogether.
I had to get one final image of it, so I drove a few miles from work and got my homemade 200mm F/5 Newtonian out in a corn field at 32 degrees Celsius.
This was the view that I had on the laptop screen (minus the color, added later during processing):
The above image was published on the first page of SpaceWeather on the same day it was acquired.
The same image was also posted on the EarthSky.org website.
The equipment: 200mm F/5 homemade Newtonian working at F/15, Astrosolar full aperture filter, ASI 120MM-S camera with Baader Red filter. Seeing: 6-7/10.
And the normally orientated views, greyscale and color:
Hope another group like 2403 will be visible on the Sun soon.
