Supernova SN2020ue 2019017
A quick imaging session on iTelescope T21 resulted in this image of the supernova in NGC 4636.
The supernova seems brighter than at discovery, by comparison with the star to thge below left in this image. I’m not altogether sure how to measure the magnitudes of these stars. Using the star at below left the GAIA ‘green’ magnitude is 12.6 (or so), perhaps. More accurate measurements are needed.
For reference the star below left is in the GAIA catalogue:

Will be interesting to see how this SN develops over the next few weeks.
