This discovery of what appears to be a classical nova couldn't arrive at 
a worse time (LMC in May), but the reported eclipses and long P_orb make 
it an important star to know about.  Australites, see what you can learn 
about it!

I've completed preliminary analysis on two program stars - V1223 Sgr and 
LN UMa.  Both can be taken off the menu, though it would be nice to 
sneak in some V1223 observations *late* in the observing season 
(September).  V803 Cen remains a very good target.

OGLE-IV Pre-discovery Observations of
MASTER OT J051032.58-6921

Excerpt:
"... The star was severely saturated in the image
acquired on 2016 April 28.97626 UT, meaning
it was brighter than I=11 mag. The last pre-
eruption image was taken eight nights earlier
(on April 21.00403 UT).
The progenitor was clearly visible in the OGLE
images ... and showed eclipsing-like variability
with a period of 2.6508 +/- 0.0002 d. ..."
