[vsnet-alert 5921] IX Dra likely superoutburst continues

IX Dra likely superoutburst continues

  As reported by Poyner and Reszelski, the SU UMa-type dwarf nova IX Dra
is undergoing an outburst.  The duration of the present outburst suggests
a superoutburst.  The last superoutburst occurred on Apr. 13 (vsnet-alert
5810 and 5812).  If the present outburst is a genuine superoutburst,
the supercycle becomes as short as 36 d (!), which qualifies the ER UMa
nature suggested in vsnet-alert 5370.  The VSNET Collaboration team
is already undertaking on the current outburst, and will inform the
result when the analysis is over.  We strongly recommend further detailed
observations of this dwarf nova for the coming outbursts.
