PNV J17580848-3005376: possible nova (10 mag) in Sagittarius

Possible nova at 17 58 08.48 -30 05 37.6 (J2000.0), for details see

Complete ASAS-SN Sky Patrol (Shappee et al. 2014ApJ...788...48S and Kochanek et al. 2017PASP..129j4502K) light curve and data (the brightening on 2019 April 2.262 UT is very likely not real):

The (likely) eruption began between 2020 July 10 and 15.

Spectroscopy, multiband photometry, and precise astrometry are urgently required.

Clear skies,
Patrick

Added to VSX

Hi Antonio,
I added it to VSX.
Two (possible) novae in a row, who would have thought?

Cheers,
Sebastian

Hi Antonio,

You can use either PNV J17580848-3005376 or N Sgr 2020 No. 3 for the name. There is no GCVS identification yet.

Thanks for your excellent obsevation and for submitting it to the AAVSO International Database so it can be used in studies of this nova!

Good observing,

Date+time of Modic's observations?

HI Robert,

What is the date/time of Bob Modic's CCD images? It's important to include that information for reference.

thanks,

Elizabeth
