Message-ID: <4A0228B3.8000600@astro.columbia.edu>


Pardon me for the multiple postings, but I'd like to promote this one 
for CBAers as well.  Jonathan and I will both be there, along with Jerry 
and several other CBAers (I think Tom Krajci, Tut Campbell, Bob Koff, 
and probably others).  At some point we'll have a CBA sub-meeting 
somewhere in there.

As of yesterday, the Northwoods Resort still had some rooms, though not 
many.

The Joint meeting is going to be the biggest meeting of SAS in its history.
We already have over 150 registered for the Symposium. A fair number of
CBA'ers will be coming including representation from Belgium, UK and New
Zealand. The Data mining and Photometry workshops each have over 70
registered.

The dates are May 19-21 and it is held in Big Bear, California. Check out
the Society web site at www.scoastrosci.org.

See you there.

Subject: (cba:news) CR Boo - faint?
Message-ID: <4A029F65.4000602@astro.columbia.edu>

Dear CBAers,

Tut Campbell reported CR Boo very faint last night.  This could be one 
of its very rare excursions to a low state; if so, it would be a very 
high priority target (we've never caught it in such a state, despite 
very frequent looking).  You might get ugly data at 17.5 with a bright 
Moon, but it would be mighty useful - except on the nights when the Moon 
makes its monthly close pass.

Subject: (cba:news) Possible nova in Centaurus ASAS 133116-6357.6]
Message-ID: <4A0ABA7F.3040409@astro.columbia.edu>

Dear CBAers,

This looks like a pretty good nova candidate, and is well placed in the 
evening sky.  We should definitely amp up our coverage of novae.  We 
don't generally expect significant variation on our usual timescale of 
minutes/hours.  But we really oughta invest some more time in looking, 
because some novae show definite fast variability... and also on the 
general principle that we don't really know until we look.

If it's basically a light bulb all night long, then revisit a few weeks 
  later and try again.  This bright (likely) nova will probably be a 
target of some UV/X-ray coverage over the next few weeks.  As usual, a V 
filter would be nice for such a bright star.

Possible nova in Centaurus ASAS 133116-6357.6

Grzegorz Pojmanski, Dorota Szczygiel and Bogumil Pilecki of Warsaw
University Astronomical Observatory report:
ASAS3V instrument of The All Sky Automated Survey (telephoto lens 200/2.8,
diameter 70mm + CCD + Johnsons V  filter, 3 minute exposures, pixel size
14.8 arcsec, rms astrometric accuracy - 4  arcsec)

has detected possible outburst of nova  located at
at RA = 13h 31m 16s  DEC = -63d 57'.6

Object was V=8.53 at its maximum and is currently fading at the rate
of 0.2 mag/day.

Several faint sources are present close to this position in the DSS 
image and
USNO-B catalog, so no progenitor could be suggested based on the ASAS
astrometry.

Message-ID: <4A1CB3BA.2050705@astro.columbia.edu>

DEar CBAers,

I'm not sure this is the first outburst since the long low state, but 
it's a rise from 17th magnitude - so is a HIGH priority for observing!

Dear All,

just started a short run on this and the star is clearly
humping.

Best,
