Dear CBAers,

Patrick Schmeer found T Leo (QZ Vir) at 11th magnitude yesterday, in a 
possible extraterrestrial display of Obamamania.  Is it a superoutburst? 
  Someone probably knows already, but has not yet reported.  But the 
chances are quite good.  It's a very good season for Leo, and the 
equatorial location is good for all.  A good chance to get very 
extensive coverage of this quite nearby star - let's make it a major 
target!  Assuming it's a super - the humps are the dead giveaway.

Taichi Kato's post below makes 0329+12 a very tempting target too.  Very 
little known about this star.  Personally I'm a little skeptical of this 
one... but it's really important if it's true!

My observing class starts tomorrow, and I return to regular nightly 
observing for the first time in about 15 years.  Wow!  Not many CVs on 
the agenda in our milky New York skies... but it should be lots of fun.

Fire away, and let us know what you find on these interesting stars!
