Re: Nova LMC 1968

We were able to make 5 spectra of this nova, but it became too faint to have a spectrum.

The magnitudes given are those obtained from the AAVSO in V and CV bands

New symbiotic stars discovery

With our 2SPOT team, and especially Lionel (and the invaluable help of Jaroslav Merc), we have set up a method for finding new symbiotic stars, which follows on from what Lionel presented during the congress in Prague on June 7th, the presentation of which can be found here : http://symbiotics2024.c...

conference 'Symbiotic stars, weird novae, and related embarrassing binaries'

The 2SPOT team was present at the conferences on novae and symbiotic stars in Prague last week: http://symbiotics2024.cuni.cz/home.html We presented our work in 3 presentations that you can find here: http://symbiotics2024.cuni.cz/program.html our presentations are as of June 7. We had the opportuni...

Re: SN 2024ggi a nearby type II supernova in NGC3621 (Dec -32 deg)

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.

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.
