I have just got round to watching David’s Sky Notes which I missed as I had to catch my last train north.
SN2018gj imaged there by David Swan and Peter Carson is interestingly another supernova discovered and confirmed spectroscopically by amateurs. (Patrick Wiggins and Etienne Bertrand respectively)
Patrick Wiggins first put the news of his possible discovery out on the supernova discussion forum where he was advised to upload it onto the Transient Name Server post haste !
I was clouded out but realised it was potentially bright enough to be recorded spectroscopically using a standard ALPY 600 so I put an alert out on the ARAS forum which Etienne picked up.
The confirming spectrum was taken just 9 hours after the discovery
