COMET P/2007 A1 (LOVAS)
      Comet P/1986 W1 (= 1986 XIII = 1986p; cf. IAUC 4276) has been
accidentally rediscovered on Catalina Sky Survey images taken with
the 0.68-m Schmidt telescope on Jan. 9 by R. A. Kowalski, the comet
appearing diffuse with a slightly condensed core approximately 1´
in diameter, and a more intense core approximately 20" in diameter.
Confirming CCD frames in good seeing by E. J. Christensen with the
Mt. Lemmon 1.5-m reflector on the same night show a moderately
condensed 10" coma with a diffuse tail extending 30" toward p.a.
about 75 deg, while his images on Jan. 10 display a moderately
condensed 10" inner coma surrounded by a faint 30" outer coma (the
latter being elongated toward p.a. 60 deg).  Following posting on
the Minor Planet Center´s ´NEOCP´ website, additional astrometry
below was reported by G. Hug, B. Twarog, and D. Tibbets (Eskridge,
KS, 0.7-m reflector; object diffuse) and by J. E. McGaha (Tucson,
AZ, 0.30-m reflector).  The indicated correction to the prediction
by S. Nakano in the 2006 Comet Handbook (and NK 946) is Delta(T)
+18.6 days.
