Description

Back to the Esprit. M101 off-center because I wanted to have NGC 5485, NGC 5486 and the neighborhood in view as well.

Update: turns out I got lucky. The subs were taken on 2023-05-18 21:24 till 01:40 (approx, UTC). According to https://www.wis-tns.org/object/2023ixf it was discovered 2023-05-19 ~17:30 utc (T), so my observation started T-20h. 

Update2: existence of this data was published as an astronote on the Transient Name Server: https://www.wis-tns.org/astronotes/astronote/2023-125

I divided my subs in 4 stack to see the growth over time:

Meanwhile my observation shows up in magnitude graphs:

A big shout-out to @Keming (Dr Keming Zhang, UC Berkeley) who found my photo and filed a report to TNS.

What a difference a few days make (2023-05-18 vs 2023-05-23):
