Information related to the Galileo G7 and G8 encounters is available.
WOULD THOSE OF YOU WHO HAVE CORRESPONDING OBSERVATIONS PLEASE SEND THEM TO US?

Reta

The following HST images were obtained with the WFPC2 in the PC mode. These observations were biased toward the northern hemisphere but include regions to 35 deg south latitudes. If you need to collaborate to interpret your data sets contact PI Reta Beebe (rbeebe@nmsu.edu) The data consist of multicolor images during 2 consecutive orbits and another single orbit 10 hours later.

Infrared Observations reported by Glen Orton
Thurs May 1 14:44 MDT 1997

On behalf of myself, Brendan Fisher, Terry Martin and Bob West, I report that the G7 support observations were very successful from Mauna Kea (NASA IRTF and U. Hawaii 88-inch), despite some early weather problems and some equipment problems.

Near-infrared and middle-infrared observations were made using NIMS (the IRTF facility camera) and MIRLIN (the JPL middle-infrared camera) on UT 1997 April 2,3 and 5. (April 4 was used by Iophiles!). Several of these observations are being used now to help the repointing of some of the NIMS and PPR remote sensing science after an error caused the Galileo star-tracking capability to stop and only gyro stability was available.

Good middle-infrared images (7 - 24 microns) were obtained despite the fact that 1 out of 2 buffer leads from the MIRLIN detector array was not operating correctly and the raw images were missing 4 lines out of every 8 rows. This is being done using the fact that 10 - 12 frames in total were made of Jupiter at each wavelength, and the position of the planet was dithered on the array.

Tip-tilt corrected CCD images were obtained from the UH88-inch on April 3 - 7 UT in a brief period between Jupiter rising and dawn at wavelengths between 618 and 945 nm.

Processing for all the data are underway.

MIRLIN and NSFCAM use is planned for the G7 encounter (May 4 - 10), as is the UH88-inch CCD system. The IRTF will be off-line for shutter repair between May 10 and June 27, so the Galileo support program will both close and re-open (we hope!) the facility.
