Supernova SN 2014dt in Messier 61: a new image (21 Dec. 2014)
After almost two months, at Virtual Telescope we visited supernova SN 2014dt and its hosting galaxy Messier 61 again.
The picture comes from the average of two, 180-seconds exposures, remotely collected with the PlaneWave 17″+Paramount ME+SBIG STL-6303E robotic unit part of the Virtual Telescope Project. The source was at less than 20 deg above the eastern horizon. The transient was estimated at mag. 15.9 (R mags for the reference stars from UCAC-4), almost 3 magnitudes fainter than on 31 Oct. 2014.
