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?
