International Jupiter Watch
Date: Fri 31 Mar 2000 From: John T Clarke (email@example.com) There will be coordinated observations by Cassini of the solar wind approaching Jupiter in Dec. 2000 while HST makes observations of the UV aurora. Next, in Jan. 2001 Cassini will observe the night side aurora while HST observes the day side. We have been granted 35 orbits for this program on HST, which is an unusually large program. This means that we will have a great chance to study Jupiter next winter, and also that we are unlikely to obtain a lot of time in the near future after this. For both reasons, I strongly encourage all other observers of Jupiter to join us in this campaign of observations. Here are the requested observing times for this campaign: Observations prior to closest approach Cassini solar wind times HST observing times 1. Day 344 19UT - Day 345 19UT Day 345 11-19 UT 2. Day 348 19UT - Day 349 19UT Day 349 11-19 UT 3. Day 350 19UT - Day 351 19UT Day 351 11-19 UT 4. Day 352 19UT - Day 353 19UT Day 353 11-19 UT Observations with Cassini ORS after closest approach Cassini ORS observing time HST observing time 1. CA+9d 6UT - CA+10d 2UT CA+9d 11-19 UT 2. CA+14d 6UT - CA+15d 2UT CA+14d 11-19 UT 3. CA+21d 6UT - CA+22d 2UT CA+21d 11-19 UT notes: - HST dates in Dec. 2000 are 10, 14, 16, 18 Dec. - HST dates in Jan. 2001 are 8,13,20 Jan. - CA = 30 Dec. 2000 Best regards, John
