Transit plots indicate that one of the SSTB ovals is possibly in conjunction
with the GRS at this time. Drift plots indicate this would have occurred on
or about Oct 31.

Observing schedules reported:
- Drake Deming (GSFC) and Joe Harrington (Cornell U.) observed Jupiter
at the IRTF with MIRLIN and NSFCAM on 11 October and with MIRLIN only
on 20 October 1998. MIRLIN observations were at 7.85 (CVF) and 20 (Q3
filter) microns. NSFCAM observations were with the Orton Galileo
support macro, plus some additional images at 5 microns (M' +
polarizer).
Joe Harrington
jh@oobleck.tn.cornell.edu
- Glenn Orton, Brendan Fisher have observing time coincident with the
18th and 19th orbit encounters of Galileo at the NASA Infrared Telescope
Facility.
1998 November 21 - 23
1999 January 29 - February 1
On both dates, the near-infrared facility camera (NSFCAM) will be used.
In November (possibly Jan/Feb of 1999) the mid-ir camera MIRAC3 will be used.
We are interested in visual (CCD) observing in several colors that might be
coincident with these dates, particularly in Jan/Feb when the Galileo mission
will be making atmospheric-intensive observations.
GSO, BMF
go@orton.jpl.nasa.gov
- I observed Saturn this morning (11/3 12:20 - 5:00 am MST) and will be doing
the same tomorrow morning same times.
The observations are with GRIM at APO. The filters range from 1 - 2.3 microns.
