COMET P/2006 W2 (LONEOS)
E. J. Christensen, Lunar and Planetary Laboratory, University
of Arizona, reports the recovery of P/2001 WF_2 (cf. IAUC 7827)
with the Catalina 0.68-m Schmidt telescope, with no sign of coma in
three co-added 60-s CCD exposures on Nov. 18.3 UT or in four 30-s
stacked images from Nov. 19.24-19.25. The indicated correction to
the prediction on MPC 51822 is Delta(T) = -0.05 day.

SUPERNOVAE 2006nf-2006nq
Eleven new type-Ia supernovae (designated 2006nf-2006np, all
in the magnitude range g = 21.0-23.0) found between Oct. 17 and
Nov. 10 by the Sloan Digital Sky Survey II collaboration have been
reported by J. Frieman and announced on CBET 740. The "Nearby
Supernova Factory" collaboration reports the discovery of the
type-II supernova 2006nq (R about 19.7) in NEAT images obtained on
Nov. 13.2 UT (details on CBET 741).
