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
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.
Northern lights in the City: On March 17-18, 2015, we were lucky to witness some very strong Aurorae as far south as Stockholm. They appeared after a strong CME -Coronal Mass Ejection- and southward pointing interplanetary magnetic field Bz. It was the strongest in many years. One of the photos shows a strong outburst over the roof tops. It was taken by Anna Hamberg. Next, Anna, Oliver and myself witnessed some typical curtain forms over the Old town. The view is from Södermalm.
