Dear colleagues,

 

I'm right now (2018, Jun 13/14) doing unfiltered CCD photometry of SDSS
J141118.31+481257.6 at CBA Belgium Observatory. The lightcurve (see below)
of this object is showing some very interesting behaviour: during the first
30 min of my session, the variable was around mag 15.4 CV showing small
humps. It then started to brighten by almost 1.0 mag (to mag 14.4 CV) over
the course of the next 1 hour. It will be interesting to see how the
lightcurve continues to develop, but I might have captured the start of a
rebrightening of this target. Very exciting!

 

It would be nice if someone can take over around 01h30m UT tonight, when the
sky becomes too light in Belgium, to ensure we have continued coverage of
this target in this stage of its outburst.

 

Best regards

Tonny
