Supernova SN 2017eaw and NGC 6946, an update – 9 July 2017
We continue monitoring supernova SN 2017eaw in the spiral galaxy NGC 6946. Discovered almost two months ago, its brightness is still at its maximum.
The image above is the average of twenty, 90-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. At the imaging time, a very bright full Moon was high in the sky.
Comparing these observations with what we measured almost one month ago from Arizona, it is clear that the transient keeps quite well its brightness: SN 2017eaw magnitude was estimated to be at mag. 12.9 (unfiltered, R-mags for the reference stars from UCAC-4), that is very close to its peak. So the object is in its expected plateau phase.
Further follow-up will follow in the next months.
