[vsnet-alert 13747] (fwd) NSV01436 bright outburst

   Fwd from aavso-discussion by Mike Linnolt.
   The object is potentially an IP with brief outbursts.

Just observed it a few hours ago at v=12.4 this is the brightest outburst
since its "reactivation" last year.
A brief summary of the star:
This is one of the old Ross variables which was discovered early in the 20th
century and had only a few historically recorded outbursts. It was found to
be around v=18 to 19 several times in the past decade. Last year it began
frequent eruptions to v~13, and each eruption seems to be getting brighter
at the peak, as today it is at its brightest in the last 50 years at least!
Could this be a UGZ which has been in a standstill around V~16 the past
decade or more, finally resuming its outbursting behavior? Very unusual
variable, indeed.
