The sun today

Sunspots – Visible Light Filter

As we finally enter September month followed by darker and still warm nights, I decided to assemble my telescope during a semi-cloudy day and take a few shots of the sun. To my surprise the surface was covered with several sunspots, more than it has been in a long time.

The image to the left was taken with my Canon EOS 50D at ISO600, shutter speed 1/8000 and a temperature balance 7000K. The sunspots visible here are 1281, 1282, 1283, 1277 and 1279.

The 17th of September we will have our annual celebration of “Kulturnatten” (culture night), which means many institutions at Lund’s university will have open house from morning to night. The physics and astronomy department will offer laser shows, barbecue,  exhibitions of light and other experiments, star gazing through telescopes and much more. Everyone is welcome to visit us, regardless of age and of course both food and drink and everything else is for free!
