[vsnet-alert 7619] XZ Eri outburst (eclipsing system, SU UMa-type candidate)



XZ Eri outburst (eclipsing system, SU UMa-type candidate)

Dear Colleagues,

   Rod Stubbings reported that the eclipsing dwarf nova XZ Eri is undergoing
an outburst.

Subject: [vsnet-outburst 5125] XZ Eri outburst

XZ Eri is in outburst.

ERIXZ          030127.476   150  Stu.RASNZ                          
ERIXZ          030127.521   150  Stu.RASNZ 

===

   The object has an orbital period of 0.0612 d (Woudt and Warner 2001,
MNRAS 328, 158).  The object is thus most likely an SU UMa-type dwarf
nova!  Although the present magnitude is fainter than the past likely
superoutbursts, the lack of recent outbursts makes the present outburst
a good candidate for detailed photometric observations!  Please observe
the target as long as possible (preferably more than 2 orbital cycles).
Use short exposure times (less than 1 min) to resolve eclipses.
Observers with a larger aperture may try high-speed photometry, with
exposure times less than 10s.

   XZ Eri is located at 04:11:25.76 -15:23:24.3 (J2000.0), so sufficient
coverage can be expected even at medium northern latitudes.

   The object is now the prime target for the VSNET Collaboration!

Regards,
Taichi Kato
