Very nice result especially at M 13.8 ! What size telescope was used Robin?

Cheers,
Hamish

Hi All, Hi Robin,

After a second try, I could obtain enough signal yesterday evening. Here is below my contribution:
Sn2020 uxz under Rspec - 7 x 600 sec - 18 oct 2020

My continuum is rather flat, especially in the Blue. Can't explain if this is because of the star in explosion or a bad instrumental response obtained. That being said, Gelato has correctly matched with a type Ia also proposed :
Gelato - matching with 2006gz

This Sn is still exiting to follow in the days to come, not far away from Mars at the moment in the sky. Here is a picture of my guiding camera below :

Hi Hamish

280mm (The Celestron C11 at f5.5). This magnitude is ok for me with the ALPY 600. Even the individual 10min spectra show the main features

I can get to ~mag 15.5 with the standard ALPY, though at reduced SNR and mag 16-5-17 with my modified ALPY 200 at R~130 eg for faint supernovae classification

Cheers

A spectrum from 20201103, approximately 12 days post maximum. Significant evolution since pre maximum

but still a good match to a typical type Ia

It also match corectly in GELATO with the SN2003du, in its 19th post max:

Nice result Frederic , according to LCG the magnitude is now around 14.4 ... not a bad performance with a modest Newton skywatcher 250mm. :) .

Il faudrait nous préciser avec quel spectro tu as fait le spectre, le temps de pose, la caméra, etc...
Sinon, on a pas de moyen de comparer tel ou tel résultat. ;)

Comme Olivier,
Il faut bien renseigner les champs, surtout quand il y a de bons résultats, ça fait pro !
