3/30/99 Bathilde Update


 Dan,

      Below is my nominal prediction for the April 1st occultation by
 441 Bathilde.  I'm copying this to the observers to let them know
 that you might be trying this from the air, so we might get an
 astrometic update for it.  The IOTA chart for it is on the Web at
 http://www.anomalies.com/iotaweb/index.htm under "Future events".

      Also, Ron Stone earlier today provided
 more observations for 121 Hermione, so that event can (and should)
 now be updated.  I like Federspiel's update for Hermione, since the
 path is now passing over Maryland, so I hope the new path holds up,
 although that would not be good for you.  Sorry to hear that Murphy
 struck again on the airplane for Lachesis.

      David
