We observed the variable star RXJ1643.7+3402 at the RIT Observatory
on Apr 12, 2002, UT. Data are taken from unfiltered 15-second exposures
through a 10-inch f/6.3 telescope onto SBIG ST-8 CCD camera.
The measurements span a little more than 1 hour, and were taken
through thin cirrus.
The star varies with an amplitude of up to 0.3 mag, on timescales
of 10-30 minutes. You can see a finding chart and read more about

It looks like this star will be a good target for small telescopes.
