The galaxy M51 and polar light

nobody@ipernity.com (Ko Hummel) — Mon, 17 Mar 2025 17:45:00 +0000

Exactly 10 years ago I made this pcture (left frame) of the Whirlpool galaxy M51 in the constelation Ursa Major, not realizing that the aurora was very active. I was disapointed by the bad quality of the exposures. The next day the newspapers reported that the polar light had been visible. So this was, by accident my first encounter with the polar light..
The right frame shows a "normal" exposure of M51 in absence of the polar light
The sun is this year still in an active phase, so be allert.

Reprocessed pictures (three) taken on 17-03-2015. I am now convinced that the reddish background in part of the pictures is in fact caused by the polar light. At that time I didn't realize it was visible in large parts of northern Europe

Total exposure 3x60 seconds with ISO 3200

The left picture was taken during a period of polar light activity of which I was not aware at that time.
The PiP shows a picture of M51, taken in the same night.
