Supernovae 2018gj, 07 March 2018
On 14 January 2018, Patrick Wiggins in Toele, Utah, discovered supernova SN 2018gj in galaxy NGC6217. (The galaxy is in the constellation Ursa Major.) The supernova was of magnitude 14 at the time of discovery, and so within range of relatively modest instruments.
The following montage shows images captured with an SBIG8300 camera and a Celestron C8, with 3 minute and 18 minute exposures. For comparison, a pre-discovery and a post-discovery image from the Sloan online DSS (Digital Sky Survey) are also shown.
