Gamma-ray burst GRB 180205A

5.2.2018 at 20.25 - Varkaus, Härkämäki (I)
Ville Miettinen, Janne Voutilainen, Warkauden Kassiopeia

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 " http://nova.astrometry.net/user_images/19750...

C / 2016 VZ18 is the discovery of PANSTARRS 1 (FISH FISH) from last fall. Ville stacked the comet and left a few observations in the middle to make room for the comet, the star string :). This technique was invented when measuring the brightness of a comet. Kari stacked according to the stars, from which you can see the movement of the comet in 20 min. The comet is perhaps at its brightest right now.
