NGC 3938 and supernova SN 2017ein: a new image (22 June 2017)
After our previous visit to the wonderful spiral galaxy NGC 3938 and its supernova SN 2017 ein, we managed to observe it again, finding it significantly brighter.
The image above is the average of seven, 300-seconds exposures, remotely taken with “Elena” (PlaneWave 17″+Paramount ME+SBIG STL-6303E) robotic unit available at Virtual Telescope. The image scale is 1.2″/pixel.
Comparing these observations with what we obtained about one month ago, it is easy to see how the transient increased its brightness a lot: SN 2017ein magnitude was estimated to be at mag. 15.4 (unfiltered, R-mags for the reference stars from UCAC-4), 1.5 mags brighter.
We plan to do some further follow-up, as long as the target will be accessible from our observing sites.
