Subject: TOUTATIS Updates For End of Dec
Summary: Forwarded Info on occultations for Tutatis
Keywords: Toutatis, Occultation
Organization: Johns Hopkins University
Date: 21 Dec 92 14:58:14 GMT

The following information concerning predictions for occultations by
Toutatis was received from David Dunam, International Occultation
Timing Association.  David doesn't have usenet access, but can be
reached via e-mail at

     On Dec. 23, one path passes north of Los Angeles and south of San 
Francisco.  On Dec. 26, one crosses southern Alberta and the northern Rocky 
Mountain states.  On Dec. 31, one passes over the Boston area, near Ottawa, 
and north of Winnipeg.  Details are below.

 MORE UPDATED PREDICTIONS FOR OCCULTATIONS BY TOUTATIS - Yeomans-D Ephem.

     The paths for occultations by Toutatis during late December are
shown in the maps in the November issue of Occultation Newsletter.
Detailed path predictions are given at the end of this message.  Bracketing
these paths with observers could provide a high-accuracy astrometric fix on
Toutatis that would complement radar data to improve the orbit.
     For each occultation, header lines only identify the star, date,
and time of geocentric closest approach.  The first table gives
conditions for the event, the second is a table interpolated at integral
degrees of longitude, and that is followed by a list of the coordinates
of time points at one-minute intervals.  Angles are in degrees unless
otherwise stated.
     The "YeomansD" ephemeris used to calculate the updated predictions
is based on radar ranging to Toutatis from Nov. 27 to Dec. 11, and on
optical data from 1934 to 1992 Dec. 11.  On Dec. 23, it is running about
0.1" north and with 0.0 minute time correction from the YeomansA ephemeris
on which the the Occultation Newsletter tables and maps are based; by Dec.
31, the difference is 0.2" north with again zero time correction.  This
means that the paths are very close to the center of the paths shown in
Occultation Newsletter.
     The radar data show that Toutatis' diameter is 2 km, not 3.5 km.  The
YeomansD orbit continues to satisfy the radar observations very accurately,
so there is no need to update it, according to Yeomans.  Star position
error is now dominant now that Toutatis is rushing away from the Earth.
Typical errors are indicated below:

       Star catalog source   C     X     R or U
       Typical error        1.0"   0.6"   0.3"
       Dec. 23              74 km  44 km  22 km
       Dec. 31             114 km  68 km  34 km

The distances are the half-width of the path uncertainty range.  The source
catalog codes are given under "S" in the 2nd table on p. 235 of the Nov.
issue of Occultation Newsletter; C = Astrographic Catalog, etc.  I think
that occultation observations would be valuable astrometrically to refine
the orbit more, complementing the radar data that gives precise distance
but not so good accuracy in the sky plane.  Ideally, enough observers
should bracket the path to ensure that two or more of them see an
occultation (that is, 1.5 km or smaller separation), since such short
events could also be caused by birds.  But this will be difficult near the
end of the month as the star position uncertainty path widths increase.
It seems not effective to continue to try to play this game in 1993.
     Good luck with observing these events!   David Dunham, 1992 Dec. 18
