[vsnet-alert 7283] V589 Her is a UGSU type dwarf nova in 'period gap'



Dear colleagues,

I have received two good quality data sets of V589 Her time-series
photometry observations from Jerry Foote (CBA Utah).
When combining these data with my own V589 Her data, yielding a total of 841
observations, I obtain a firm superhump period of 0.0947 +/- 0.0005 d, using
the PDM technique. This turns V589 Her into a UGSU type dwarf nova inside
the so called 'period gap' !

The periodogram and phase diagram derived from the combined observations is
shown on my web site.

We are expecting a few more data sets on V589 Her.

Best regards,
