Quiet aurora band

A couple of weeks ago on Friday there was a nice bright evening at Syötte and at the same time there were northern lights in the north and northeast and a milky way in the south (this picture as a separate observation). The time of the lively warp of the northern lights ended relatively early at about 10 p.m. Camera Sony a7M3 and lenses Samyang 12mm f2.8 fisheye and Laowa 15mm.

Milky way

For a long time, a completely clear sky was promised but the northern lights forecast was poor. So the Milky Way was more visible then. #bongaalinnunrata

COSMO-SkyMed 1

I photographed the starry sky on Sunday, February 28, 2016, and after transferring the images to a computer, I noticed a satellite footprint in one image, which brightens considerably for a moment. The picture is taken roughly straight up. Exposure time 10 s, aperture 2, focal length 24mm and ISO 1600. What causes such momentary brightness in the satellite or its orbit?

Rocket-related clouds

I was filming the northern lights in Iin Praava when a northeastern sky showed a tiny slow-moving cloud of light that is apparently the launch of a satellite Sentinel 3A from Russia. The shutter speed of the image is 5 seconds. #raketti: Vaccines #satelliitti: Sentinel 3A (2016-011A)
