confirmation of sn2019np

Note that although an early spectrum of sn2019np was taken by the Li-Jiang telescope, the official confirming spectrum was actually taken several hours earlier using Faulkes Telescope North and uploaded to the Transient Name Server (As it happens 4 minutes before the Atel #12374 was issued, though since 2016 the TNS has been the official IAU system for recording supernova discoveries and confirmation)

There are also three amateur spectra of this SN in the BAA Spectroscopic database

and more spectra on the ARAS forum here covering the evolution up to currently 17th Feb
