* Discovery Information

This is a variable object detected from the 300-mm camera lens or 18-cm reflector images of Comet 52P/Harrington-Abell taken between Dec. 9 and 20 by Ken-ichi Kadota, Ageo City, Saitama, Japan.

The magnitude estimated by the PIXY system show that this object is about one mag fainter than usual on Dec. 17. Because it is as bright as usual on the next day, it is probably an eclipsing binary.

* Special Notes

Discovered from the observations of Comet 52P/Harrington-Abell. The comet was at apogee when brightest in 1998 December. Stars near by the comet were observed in details by chance, and the variation of MisV0002 was discovered.

Kazuhiro Nakajima's observations revealed it is a W UMa-type (EW) eclipsing variable with a period of 0.3303555 days, brightness range of 1.0 mag.
