COMET 73P/SCHWASSMANN-WACHMANN
     Further to CBET 439, E. J. Christensen, Mt. Lemmon Survey, has reported
four further components of comet 73P from observations with the 1.5-m reflector
on Mar. 24.5 and 25.5 UT (and in some cases from Mar. 23.5).  Component P,
with magnitude estimates in the range 19.8-21.7, has positions corresponding
to T = 2006 June 7.88 TT.  Component Q, of mag 20.7-21.3, has T = 2006 June
7.74.  Component R, of mag 20.5-20.8, has T = 2006 June 8.20.  Component S,
of mag 20.9=21.5, has T only some 0.001 day earlier than component K, which
has now been redetected at mag 20.9-21.3.  The astrometric observations
are provided on MPEC 2006-F33.
