[vsnet-campaign-orion 100] PX Vul

[Taichi Kato]

  I have incidentally noticed that the pre-main sequence star PX Vul
underwent a very deep fading as indicated by the following ASAS-3
light curve:

  The object is located close to the very familiar Herbig Ae/Be
star WW Vul.  Being reasonably bright (and similar variability
pattern to that of WW Vul), PX Vul deserves wider attention.
