[vsnet-alert 4892] LX Ser activity?

LX Ser activity?

  Recent observations suggests that the eclipsing novalike object LX Ser
tends to vary in greater amplitudes than in recent years.  This may be
a signature of weak dwarf nova-type activity.  The past long-lasting
"NL"-state may have been extended standstills.  If the current activity
leads to dwarf nova outbursts, this eclipsing system may provide a unique
opportunity to investigate the disk structure of Z Cam-type dwarf nova.
Careful and continued observations are strongly encourged.  CCD observers
are also suggested to monitor this object to see whether reported variation
actually reflects dwarf nova-type variation.  If the variability is
confirmed, eclipse observations are strongly requested.  Please forward
your findings to vsnet-campaign.
