> Dear Colleagues,
> 
> Our observation revealed that the ongoing outburst in PG 1510+234
> (=NSV06990 = Ser1 in Downes & Shara(1993)) has been lasting for at
> least three days and the superhumps with an amplitude of ~0.3 mag
> clearly exist on April 23.  Although the superhump period can not
> be measured precisely due to shortness of the coverage, it seems
> to exceed 2 hours.  It was proved that PG 1510+234 is an SU UMa-type
> dwarf nova with a small amplitude of ~3mag.

> Dear Colleagues,

> We have just reduced the PG1510+234 data obtained in the last
> night.  The superhumps with an amplitude of ~0.3 mag still
> existed.  Surprisingly, our period analysis using the April 23
> and 24 results gives the superhump period of 0.1064 (+-0.0003)
> day (= 153.2 (+-0.4) min)!  Is PG 1510+234 located at the midst
> of the CV period gap?!
