SWIFT J1753.5-0127

    According to ATEL, Swift BAT detected a new gamma-ray source, 
which may be a new black hole transient.  It has a bright optical 
counterpart of R~15.8 at 17h53m28.3s, -01d27m06s.

    If the object is a typical black hole X-ray transient, 
time-series photometry may detect superhumps (but its period is 
probably longer than those in SU UMa; a few hours - days) 
or short-term variations of an order of seconds.
