10.06.2021 – Partial solar eclipse

Observation report

The partial solar eclipse in 2021 was already a few hours ago, but it was once again one of the astronomical events that will be remembered. This is not because I had to follow a training course in public procurement law online at the same time, but simply because it is always absolutely fascinating when the moon moves in front of the sun. It doesn’t matter at all that it only covered a good 15% of the sun this time. Every solar eclipse is a highlight, especially because it occurs much less often than, for example, lunar eclipses. 

The length of the observation report will be limited, because there is not much to tell. It was warm in summer with a maximum of + 26 ° C and by far most of the time, the sun was shining. Only individual clouds or cloud fields passed through, which sometimes hid the sun for a comparatively short time. When taking pictures of the sun in white light (filtered by a special sun filter), clouds that are passing by always look great. The Canon SX50 was used, which I used for recordings every 5-10 minutes. The aim was to create an animation that you can find here under the text. Since the sun was always the same size at 50x zoom, this was perfect for creating an animation. In addition, it was perfect with this handy camera, as I could simply take photos from the roof window parallel to the training (headset) without missing anything. That used to be a different way of tracking a solar eclipse, but it was fine. Then it was perfect that the lunch break of the training coincided exactly with the maximum phase. Here, of course, I went outside to take individual pictures of the maximum eclipse through the Maksutov telescope. You can find these below as well. Then I watched from the skylight until the end. Prepared to photograph the last percent a little more often, a slightly larger cloud then pushed itself in front of the sun – but that’s the way it is with nature :D. That is also part of it! It was an absolutely great experience again and it was really fun.




The next solar eclipse awaits us in the coming year on October 25th, 2022 with a maximum sun coverage of about 33%. But before we marvel at it, we will finally enjoy another total lunar eclipse on May 16, 2022 – if the weather is gracious to us again :D.



General information about the solar eclipse on 10th June 2021

After March 20th, 2015, when it was unfortunately overcast, we can look forward to a partial solar eclipse again this year. The moon moves in front of the sun again and will cover 24.8% of the solar disk. If the weather plays along here and, above all, you have the appropriate equipment for solar observation (please note the note!), Nothing stands in the way of successful observation. The partial phase begins at 11:21 a.m. and the maximum of the eclipse is reached around 12:23 p.m. Visibility then ends at 1:28 p.m. The sun has a pleasant height above the horizon with 52-62 °. Of course, individual sunspots would be particularly nice, because these always look very nice in the photos in connection with an eclipse.


IMPORTANT: Observations of the sun are really dangerous, if you don’t follow the inevitable safety instructions! Never look directly into the sun! Never point binoculars or telescopes without a special solar filter towards the sun! Your eyes would get immediately heavy damage or even total blindness would be the result!
