COMET P/2000 C1 = P/2006 A3 (HERGENROTHER)
     E. J. Christensen reports the recovery of comet P/2000 C1 on
90-s CCD exposures obtained on Jan. 6, 7, and 27 (initial
observation tabulated below) with the Mt. Lemmon 1.5-m reflector.
The Jan. 6 and 7 images were taken in very poor seeing and show no
obvious sign of cometary activity.  The Jan. 27 data were obtained
in good seeing, but still show no indication of cometary activity.
The object was consistently detected about 3' east of the predicted
position for P/2000 C1; the indicated correction to the predictions
on MPC 48384 and in the 2006 Comet Handbook is Delta(T) = -0.24 day.

SUPERNOVAE 2006Q, 2006R, 2006S
     Three additional apparent supernovae have been reported:
2006Q by W. Li (LOSS/KAIT; cf. IAUC 8662) and the others by T.
Puckett (cf. IAUC 8661; 2006R with A. Langoussis, and 2006S with R.
Gagliano).

(cf. CBET 381).  Additional unfiltered CCD magnitudes of 2006R in
NGC 6142:  2005 Oct. 15, [19.6; Jan. 27.36, 17.5.  Additional
approximate CCD magnitudes of 2006S in UGC 7934:  2005 Dec. 23,
