Sun - 3.7.2022 at 12.35 - 3.7.2022 at 13.00 Jyväskylä Observation number 107456

Visibility III / V

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.
