An apparently asteroidal 18th mag object discovered on 1999 November 28.94 by Korado Korlevic at Visnjan with a 0.41-m f/4.3 reflector + CCD was indicated on some of his December images to be possibly "fuzzy", and the cometary nature has been confirmed by C. Hergenrother and S. Larson, Lunar and Planetary Laboratory, who found a 13" coma elongated in p.a. 80 deg on a 600-s co-added R-band exposure taken on 2000 Feb. 7.25 UT with the 1.54-m Catalina reflector. The comet has a perihelion distance of 3.2 AU and a period of ten years. [IAUC 7368, 2000 February 18]
P/2008 R4 - Gareth Williams identified images of 1999 WJ7 in incidental astrometry taken with the 0.9-m Spacewatch telescope on September 3.24. The comet was 20th magnitude, with perihelion in 2010 February. The indicated correction to the prediction on MPC 59598 is Delta(T) = -0.3 day.
