COMET P/2008 WZ96 = P/2021 W1 (LINEAR)
E. Schwab reports the recovery of comet P/2008 WZ96 (LINEAR) in twelve
stacked 60-second exposures taken at Calar Alto-Schmidt (Z84) on Nov. 30
and Dec. 1 UT. He notes that the FWHM of the comet was 3".3 while the FWHM
of the stars was 2".7 on average. Additional astrometry was then found in
the ITF by the MPC.
