Dear CBAers,

Here's Jeremy's, and Taichi's, note re the outburst of SDSS0932+47. 
This is definitely a high priority object - usually too faint for us, 
let's jump to action now.

ER UMa is definitely worth continuing.  I assume YZ Cnc also, though I 
haven't done the analysis yet.  CP Pup and AH Men for sure.

More details in mid-week.  My brother-in-law died suddenly a few days 
ago, and my study of celestial goings-on will take a break.


SDSS J093249.57+472523.0 outburst!

    According to baavss alert, this eclipsing CV (likely SU UMa-type 
dwarf nova)
is undergoing its first-ever recorded bright outburst.
Observations are encouraged!!


SDSS J093249.57+472523.0  Mar 18.900 14.9C
CRTS has V~19. Possible IP with P_orb ~95 min and deep eclipses. See 
Homer et al. http://adsabs.harvard.edu/abs/2006AJ....131..562H
Go well!

http://adsabs.harvard.edu/abs/2004AJ....128.1882S (Porb=1.7hr?)
http://adsabs.harvard.edu/abs/2006AJ....131..562H (eclipsing P=0.0661618 d,
     X-ray obs. suggest an intermediate polar)
range: CSS range including eclipses (18.0-19.5 outside eclipses)
maximum: possible outburst (V=16.8) on GSC2.2
type: the presence of orbital humps in the orbital light curve
     would suggest a quiescent DN (qUGSU:) but with strong HeII
