Dear (southern) CBAers,

We're getting some great data from Gordon Myers this week on NR TrA, and 
the seasonal timing is mighty good.  The next couple of weeks offer a 
great opportunity to do a round-the-world sweep on this extremely 
fascinating star - which Fred Walter has been covering with spectroscopy 
since its 2008 nova eruption.  About mag 16.7.

Then there's IM Nor, a recurrent nova and a 2002 erupter - of extra 
special interest to us because its probable binary period is so short (a 
likely friend of T Pyx, which urgently needs friends).  Quite a 
challenge, around 18.5... and I believe only Berto has been able to get 
data on it.  But maybe things have changed; probably all of us, except 
for me, are slightly better photometrists than we were a few years ago. 
  On a good night, can you try to get time series on it?

joe
