M51: Hunting for the cloud
The whirlpool Galaxy M51 (NGC 5195/94) is a well observed object. You might think from an observer perspective there is not very much new, except you use the biggest / last generation telescopes. In this particular case, by surprise, it's different. reports in a preprint submitted by April 06th, 2018 "DISCOVERY OF A VAST IONIZED GAS CLOUD IN THE M51 SYSTEM" He and the Co-Authors perform very carefull ground base exposures using a 24 Inch Schmidt-Telesope located at Kit Peak with subsequent image processing and uncovers a cloud nobody has seen before.
Stimulated by this discovery, I started to work on M51 too.
SN 2018gv has been discovered by Koichi Itagaki @ January 15th, 2018 16:21:06 UT in NGC 2525 with a brightness of 16.5 mag.
Working on GAIA Photometric Alerts
Within the GAIA Science Alert project (GSA) teams a searching for transient events in the data of GAIA.
A transient event is anything in the sky which appear, changes or disapears. There is a website available which publishs transient alerts in real time: http://gsaweb.ast.cam.ac.uk/alerts/
