Re: SN 2024ggi a nearby type II supernova in NGC3621 (Dec -32 deg)
I think we're getting decent coverage from Australasia, though I hope we can keep it up long enough as it fades. Hamish also found this quite useful paper, with lots of comparisons of a a Type IIP with other examples and models. It's helpful for understanding the variety of features in both spectra ...

Re: SN 2024ggi a nearby type II supernova in NGC3621 (Dec -32 deg)
Hamish Barker, Peter Velez and I are continuing to monitor SN2024ggi - it's coming along nicely. The filled in bit where you would expect a P Cygni style absorption to the left of the H Alpha line is interesting. I'm going to try to get a spectrum with higher S/N to see if I can bring out a little m...

Re: SN 2024ggi a nearby type II supernova in NGC3621 (Dec -32 deg)
I think just a little brighter than 12th magnitude at peak in V.
Fantastic to be able to follow ixf all the way to the nebular phase. We'll have to see how far we can get with this one.

Re: SN 2024ggi a nearby type II supernova in NGC3621 (Dec -32 deg)
Thanks Olivier. Peter Velez and Hamish Barker also have some observations, so I think we may have pretty good coverage of this one. On this side of the Pacific we have been lucky with the El Nino weather this autumn. If we can keep up observations as it fades we may be able to model the SN, both in ...

Re: SN 2024ggi a nearby type II supernova in NGC3621 (Dec -32 deg)
And there's much more going on now. Nice fat H lines, as you'd expect from Type II.

Re: SN 2024ggi a nearby type II supernova in NGC3621 (Dec -32 deg)
And more structure. A bit noisier, though, especially at the red end. Whether down to terrible seeing (it was awful), moon , or what else I'm not quite sure.
The next few days are not going to be favourable for observing, so perhaps more over the weekend.

Re: SN 2024ggi a nearby type II supernova in NGC3621 (Dec -32 deg)
Further development - bit by bit. There was some high cloud around this evening, so a little more noise in spite of a longer exposure. Also there was a full moon at around the same azimuth as the target. So from here it can only get better.

Structure starting to emerge.

Not much in the way of structure emerging tonight.

Re: SN 2024ggi a nearby type II supernova in NGC3621 (Dec -32 deg)
Thanks Robin. On Sunday I initially thought I might have pointed at the wrong object, but eventually decided it was about right for an early Type II. The forecast for the coming week here is pretty good, so will hopefully capture some structure as it emerges. I've just kicked off another exposure a ...
