Supernova 2016bau in NGC 3631: an image (24 Mar. 2016)
Supernova 2016bau in NGC 3631: 24 Mar. 2016
The supernova 2016bau in NGC 3631 was imaged as part of the Virtual Telescope’s supernova follow-up program. NGC 3631 is a stunning spiral galaxy placed at 50 millions of light years, showing a remarkable arm structure, perfectly placed face-on.
The image above comes from the average of four, 120-seconds exposures, unfiltered, remotely collected with the PlaneWave 17″+Paramount ME+SBIG STL-6303E robotic unit part of the Virtual Telescope Project. The supernova was estimated at mag. 15.8 (R mags for the reference stars from UCAC-4). An extremely bright, full Moon was high in the sky at the imaging time. Spectroscopy showed this transient is a type-Ib supernova.
