Potentially bright supernova in NGC 4636

While we wait for Betelgeuse to explode ;-) , there is another supernova which has the potential to be the brightest for some time

https://wis-tns.weiz...l/object/2020ue

Discovered today at mag 15 by Koichi Itagaki and confirmed as a type Ia, this could reach brighter than mag 12 depending on the extinction in the host  galaxy.  (SN 1939A, another type Ia in the same galaxy reached mag 11.9) 

Cheers
Robin

currently mag 12.8

Currently mag 12.8 as measured by Itagaki compared with his 14.9  discovery magnitude

SN 2020ue

I measured it at 12.759CV on Jan 18.138.

Neither the BAAVSS or AAVSO databases will accept the designation SN 2020ue yet, but hopefully this will be rectified before too long following a couple of e-mails sent today.

SN 2020ue

Observations of this SN can now be entered into the BAAVSS database as SN 2020ue or SN2020ue.  Thanks Andy!

AAVSO still haven't updated VSX though, so at this time you still can't get the data into their database.

Brightened further to 12.632CV on Jan 19.222UT
