[vsnet-alert 1319] Dramatic fading of SW UMa

Dramatic fading of SW UMa

    T. Kinnunen reports the SU UMa-type dwarf nova SW UMa is dramatically
fading from one of its rare superoutbursts.  Observers are urged to monitor
whether there may be any rebrightening(s) which are usually associated
with ultrashort orbital-period systems.  A search for late superhumps
would be also important.

  Recent observations:
