Hi Ian, Tony,

There hasn’t been a whole lot of t/s on EF Peg over the years – probably because of the difficulties with the close comparison star.

Taichi Kato measured the superhump period during the 1991 superoutburst as 0.08705d (Publications of the Astronomical Society of Japan, Volume 54, Issue 1, 25 February 2002). The Porb is 0.0837d, so yes, the superhump period is longer than the orbital – as expected.

Ian Miller obtained a good run during the 2009 superoutburst (the first observed since 2001). I’m trying to find Ian Millers Psh in my files, but I don’t seem to have it for some reason. If you have Peranso, then you could get Ian’s data from the VSS database and look at it to see if the Psh has changed.

Every time my PC updated the Bios I required a new code from Tonny, so I gave up with Peranso.
