Gamma-ray burst GRB 180205A - 5.2.2018 at 20.25 Varkaus, Härkämäki Observation number 70585

Visibility I / V

On observation night, nothing was found in the uncalibrated single exposures so this did not become much exposure.

However, I calibrate and stack the images and some sort of west from the right point stands out when the image is stretched ridiculously. I still put Oksanen Arto's observation image on top as a .giff. The correspondence is pretty good so surely the observation is real. If so, this would be the first glow of the gamma-ray burst for me. :)

Edit: added eruption coordinates using astrometry: RA 08h 27m 16.68s DEC + 11 ° 32 '31.09 "
