First Results & 2 Videos of the Feb. 21st Arsinoe Occultation

New: 2003 Feb. 25
     Below are preliminary results, from northwest to
southeast across the path, for the occultation of
11.0-mag. TYC 1984-01884-1 by (404) Arsinoe on U.T.
2003 February 21.  All reported observations so far
are from California.  Below is listed the observer's
name, the location, the approximate distance from Steve
Preston's predicted central line in km, and the reported
duration in seconds, from Walter Morgan's e-mail message
of late Feb. 21 and two additional miss observations that
he didn't have.

Greg Lyzenga    Claremont     ~100sw      no occultation
Don Davies      Torrance      ~140sw      no occultation

Nolthenius recorded a possible fractional event, but it
could be due to clouds; his time doesn't seem to like up
with the others.

In Ed Morana's .avi file, the target star is in the upper
left and disappears about 4 seconds from the start.  The
"star" near the left edge, to the left of the target star,
is a hot pixel on Ed's Watec 902H camera, I believe used
with an 8-inch SCT telescope.

In Rick Baldridge's .avi file, the target star is in the 
lower left and disappears about 4 seconds from the start.
He used a 16-inch observatory telescope with a Stano
Components image intensifier and Sony camcorder to
record the image intensifier image.
