Subject: Comet 73P S-W, Chart

Hi all,
 As promised in an earlier E-M, here's a chart for the two brightest
fragments of Comet 73P Schwassmann - Wachmann. Labeled "B", and "C",
they are currently aroung magnitude 7, and are predicted to reach almost
magnitude 4 in mid-May.

These charts are for 0h UT (01.00 BST) on each date, and cover the next
20 days or so only, since if the fragments break up further, the orbits
will change.

Note the close passages of Fragment C just N of Alphecca (Alpha CrB) on
the night of 21-22 April; and just N of Zeta Hercules on the evening of
30 April, and almost crossing M57, the Ring Nebula, on 8-9 May!! I'll
update further on this if the orbit changes.

Also, the fairly close passage of fragment B North of M13, the lovely
globular cluster in Hercules (mag 5.8) in the early hours of 4 May.

Post any good images to John Hall at the address above for the IAA
website, and to Andy McCrea for STARDUST at s.mccrea980btinternet.com,
and to the IFAS website, www.irishastronomy.org



Good luck.

Clear skies,

Terry Moseley
