This from the VSNET report I received today: RX J1643.7+3402 (RA = 16h43m45s.1, Dec = +34d02'35") M. Richmond performed a time-series observation of this object, and reported that the star varies with an amplitude of up to 0.3 mag, on time scales of 10-30 minutes (vsnet-campaign-dn 2300). Is this "our" M. Richmond? Tom Droege
