which was discovered 2017-09-30 on the rise at mag 16
They are intensively following up all nearby type 1a supernova and if it is found to be 1a before Wednesday they have telescope time available. The weather forecast is not good here though so is there anyone else who would like to try for it? If you get a spectrum I can assist in the classification.
The same team are also following up my recent type 1a classifications SN2017gxq and SN2017gjn
There is clear sky forecast here, although I have a load of teaching Thursday/Friday (so mechanics of life may preclude…)
I can see the galaxy in the DSS image overlaid in CdC but coords differ from those advertised (maybe an epoch issue?). Anyway, I’ll let you know if I am game for it later this week
Interestingly the “SED machine” spectrograph they use is even lower resolution than mine. They are definitely a rival 😉
The location looks spot on to me in CdC if I overlay the DSS image so probably an epoch issue. (The TNS coordinates are J2000). It is quite close to the galaxy core though so separating it from the galaxy could be a problem.
For supernovae I use a specially modified ALPY with a lower dispersion GRISM which allows me to get down to ~mag 17.5 compared with ~mag 15.5 with the standard ALPY with my C11
