[vsnet-outburst 23284] Re: [vsnet-alert 22965] NSVS 708833 in outburst! (from ASAS-SN SkyPatrol data)

[Robin Leadbeater]

A low resolution (R~500) spectrum from last night shows an essentially 
featureless blue continuum with nothing detectable at H alpha but weak H 
beta, gamma, delta Balmer lines in absorption. Spectrum in BAA database here

A few minutes ago I had a look at the latest the ASAS-SN Sky
Patrol data (Shappee et al. 2014ApJ...788...48S and Kochanek
et al. 2017PASP..129j4502K) and noticed an outburst:
NSVS708833 20190120.422 13.94g ASN
NSVS708833 20190122.446 13.95g ASN

Precise astrometry, spectroscopy, and multiband/time-resolved
photometry are urgently required.

Clear skies,
