Spectroscopy and multiband (and time-resolved) photometry are
urgently required.

Clear skies,

However, for spectroscopically confirmed supernovae please
use "SN 20yy..." (mind the gap!) designations.

ASASSN-18abl - just discovered: bright, dramatic
outburst from a star that has never varied before,
also posted to TNS:

Please use ASAS-SN names for ASAS-SN discoveries.

No previous variability:
