    AO Octantis

    Dear CBAers,
    
    Oh yeah, I forgot in my message to discuss AO Oct.  Rod Stubbings
    reports that it rose to V=14.2 yesterday, from a pre-outburst mag of about
    21.  This is a very rare erupter, likely a WZ Sge type star.  Such stars
    have become our flat-out favorites over the years, with their long
    displays of powerful superhumps (WZ Sge, AL Com, EG Cnc, arguably DV/IY
    UMa).
    
    So *this* star should be the main focus of australites, until it fades
    again.  If that occurs soon, well then, chalk it up to another of these
    damn normal eruptions - and on to other things.  But if this is a
    supermax, it's probably going to stay bright for a few weeks, and flash
    some great superhumps at us.  So that becomes the premier target for 3
    weeks or so.  Get thee to a telescope, and let us borealites know!
    
    The star's coords appear to be 21 05 8.35 -75 21 8.3 (J2000).  There may
    be a little 18th mag guy next to the star.  If so you'll have to decide
    whether to exclude it from your aperture box, or include it cleanly.
    There's a chart in Downes and Shara.
    
    About 4 years ago Jonathan got BE Oct in supermax - how great it would be
    now to get the other of the Octans twins!
