Preliminary Report of the Chiron Appulse on 2003 March 29

No dimmings of the star have been reported in the south side of the path, and south of it.

New: 2003 March 31

      Walter Morgan observed last night's (2060) Chiron appulse from
a site near Willows, California, northwest of Sacramento about 160
km south of Steve Preston's central line and about 50 km north of
his southern limit, but no occultation occurred as he watched his
video recording.  He couldn't go much father north, where there were
thicker clouds.  Jim McCormick, 4 km north of the predicted southern
limit, also saw no events.  As far as I know, nobody else within the
predicted path, or north of it, observed the appulse.  Several more
negative reports (star monitored, no occultation seen) of the appulse
have been received south of the path; all of the observations are
summarized below.  A few others tried, but were not able to monitor
the star, mainly due to wind, cirrus, or thicker clouds.  There is a
very small chance that the path could have passed between Los Gatos
and Valencia, CA (1.5-path-width, or 0.7-sigma, south shift), but I
think it is more likely that the actual path was a little north of
the predicted one.  Anyway, thanks to all the observers who tried
this rather difficult event but potentially important event.
