[vsnet-campaign-nova 945] Re: V2540 Oph - detection of period/s

[DWest61506@aol.com]

The observations below are of V2540 Oph in V band using TYC 6248 1077 1 and TYC 6248 794 1 as comparison stars.  My check star was TYC 6248 291 1.  The standard deviation of the check star was 0.016 magnitude.  The equipment used was a 0.2 m SCT + ST-9E CCD camera.  Based on the observations below, no obvious periodicity is apparent.

Regards,
Doug West
