Congrats Nytecam, that is a very interesting series of spectra, moving from mainly thermal continuum radiation, to more an more line emission from ionized gas.

Excuse my ignorance but did you deduce this from the more pronounced spikes in the spectrum lines from 16th to 20th August?

Yes. Pure thermal (or black-body) radiation is a continuum yielding a smooth curve as a spectrum. Ionized gas produces strong emission lines showing up as spikes in the spectrum

Getting fainter.

Not possible in my 42 mm bis.

Just possible in my 80mm bins

About mag 9 I would suggest?

Just got it tonight in my 15x50is binos. Right on the limit of visibility, needed averted vision to spot it. Similar to other reports, I put it a little dimmer than the nearby mag 9.0 star, so around 9.2 ish

Not visible tonight in the binos so must be below about mag 9.3 or so which is around the limit for my binos under my skies.

Which bins did you use?

Did not get to see it yesterday, might have a bright spell tonight, and I will get out the 15x70s or the 80mm frac

My Canon 15x50is binos. As said, I think I generally find around 9.3 to 9.5 is limiting mag underused skies at home.

Definitely seems to be a big bino/small scope object now but great to have followed it all the way down from mag 4.5 (if I remember correctly).
