Perseids

7.8.2022 at 23.53 - 01.56 - Jyväskylä (III)
Harri Kiiskinen, Jyväskylän Sirius

Last night offered the observers aurora borealis and night clouds and, of course, also shooting stars. The activity of the Perseids begins to rise little by little.

4.8.2022 at 23.17 - 02.15 - Jyväskylä (II)
Harri Kiiskinen, Jyväskylän Sirius

Same catch as a couple of nights ago . The observatory had a visual observation that coincides in time with the meteor observed at 23:17:59. Unfortunately, the brightest glimpse was behind the trees as seen from Nyrölä.

At least 10 lightning strikes seen

13.7.2022 at 17.00 - 17.30 - Jyväskylä (III)
Harri Kiiskinen, Jyväskylän Sirius

For the first time this summer, a thunderstorm front hit Jyväskylä and twice on the same day. I followed the arrival of the front in Nenäinniemi, from where there is a good view of Päijänte in the south. The picture crop from the first front (at 8:50 - 9:30) was quite unfortunate, only the last picture from that show. The second one was luckier in terms of photography (photos 1-4) and I followed the approach of the front at around 16:45 - 17:30, after which heavy rain drove the cameraman away. The catch is the first flash photos of the summer.

Sun

3.7.2022 at 12.35 - 13.00 - Jyväskylä (III)
Harri Kiiskinen, Jyväskylän Sirius

Despite the flaming of the tabloids, it didn't rain a drop in Central Finland, and there was no lightning at all. Instead of flash photography, the Sun again. The main image is a color image, with the material coming towards us colored in blue and the material flowing away in orange, using the deformation of the hydrogen absorption line (The Doppler-Fizeau effect). You can also see the direction of the Sun's rotation from the colors. On the edges of the puck, there are quite spectacular bumps.

The thunderstorm did not reach Central Finland, so the weather was right for the Sun. Observations on a Sol'Ex spectral heliograph. The first image at the Ha line is 656.3 nm. In the video +/- 0.35Å band on both sides of the Ha line.
