Hello Tom,
Thanks for this useful article !!!!
We cannot do this target at the moment from our 2SPOT setup in low resolution because we are tracking other urgent targets with our eShel spectrograph.

Re: SN 2024ggi a nearby type II supernova in NGC3621 (Dec -32 deg)
bad weather in Chile (Chile's worst weather time of year).
So no spectrum of this target....

Re: AT 2024fjh -another LMC nova?
And another spectrum taken last night always with an Alpy 600, 6 exposures of 1200s because the target is going fainter than yesterday. We can see that each peak splits into two. This the velocity graph of Balmer's lines https://i.postimg.cc/PrqdSS0H/AT-2024fjh-H-velocity-small.png Evolution of the ...

Re: AT 2024fjh -another LMC nova?
A spectrum taken last night by Pascal from our team 2SPOT with our Alpy 600 spectrograph in Chile : 4 exposures of 1200s. The target is near mag. V=14, so easy target with an Alpy 600 https://i.postimg.cc/4yKjngK8/Champ-AT-2024-fjh.png and the spectrum with all Balmer's lines in emission and double ...

Re: AT 2024fjh -another LMC nova?
Too faint for an eShel spectrum, but we can try with the Alpy 600.

Re: AT2024epj - A mag 10 transient in/near the LMC
Here's the spectrum taken last night from our 2SPOT eshel spectrograph from Chile. https://i.postimg.cc/GtGMHwwh/Champ-at-2024-epj.jpg Very noisy at magnitude around V=10 and too low for an echelle spectrograph and a RC 12'. https://i.postimg.cc/NjdLWK9B/AT-2024-epj-full-small.png the two narrow emi...

Nova Oph 2024
This morning, we tried to make a spectrum of the nova Oph 2024, but were unsuccessful due to its low magnitude. But here's the spectrum and the velocity measurement on the H Alpha line https://i.postimg.cc/zGw5dLCh/Nova-Oph-2024-graphe-Small.png https://i.postimg.cc/25VYCHpQ/Nova-Oph-2024-velocity-g...
