SN 2017 cbv

[Andrew Pearce]

Hi All

There is a bright supernova (SN 2017 cbv) in NGC 5643 in Lupus. It was discovered on March 10th at around 16th magnitude but has brightened considerably since then. On March 23.62 UT I estimated visually as mag 11.4 and would be easy to see even in a 6"telescope. The AAVSO has a good chart for NGC 5643 with a range of comparison stars.

Looked at NGC 5643 last night with a 12" Dob and an 11mm EP at 135 times.
The SN was mag 11.2. I compared it with two nearby stars mag 11.2 and 11.4.

The SN was brighter last night, about mag 11.0.

Viewing it Sunday night with Sharpcap's live stack and a QHY5III290, pic from it {live screen was a lot smoother }
