Sun H-alpha

Prominences on September 9, 2018:

There were a good number of eruptive prominences on the eastern limb on Sep 9. I followed the rapid development during an hour.

First:      08:51 UT

Second: 09:51 UT

Partial Eclipse of the sun on August 11, 2018:

The partial eclipse was only a few percent at maximum, as seen from the Stockholm area. It was seen from about 10:50 to 11:30, local time. Nevertheless, the eclipse made a nice appearence together with the clearly seen prominences. At the time of the eclipse, there were no sunspots, but a few active filaments could be seen in H-alpha. These images have north up, east to the left.

The Sun in H-alpha:

There are lots of phenomena that can be viewed on the sun in H-alpha. I have used a small 60 mm solar telescope for observations, and a Skyris 274C camera for photography. This camera is based on a design by the Imaging Source. More recently, I have used an ASI183M camera and double stacking on the 60mm scope.

Solar prominences on July 8, 2017. The sunspot on the solar disc is no 2665. It shows high activity and is starting to produce flares. The prominences at the limb are hugh and bright. These two images have North to the right, and East 

is up.

Solar prominences on July 15, 2017. The sunspot on the solar disc is AR no 2665, same as above, but a week later. The seeing was good, so a lot of delicate structures can be seen. North up, East to the left.
