MW 636

Mission Week 636 starts with a short continuation of the symmetric +-50 degree rocking profile from the previous mission week. On DOY 219 (Aug 6) at 00:30 UT there is a 10 minute freeze observation during which an updated rocking profile is loaded. The updated profile is used for the remainder of the mission week. Two inertial pointings are scheduled for DOY 223 (Aug 10) at 15:28 UT and 18:38 UT to facilitate Star Tracker CCD dumps. An additional inertial pointing is scheduled for DOY 224 (Aug 11) at 16:51. Note that positive rock angles are south, and negative angles are north. (updated: 20-Jul-2020)

MW 637

Mission Week 637 starts with a short continuation of the symmetric +/-50 degree rocking profile from the previous mission week. On DOY 226 at 00:40 UT there is a 10 minute freeze observation during which updated rocking profile is loaded. The updated profile is used for the remainder of the mission week. (updated: 23-Jul-2020)

MW 638

Mission week 638 starts with a continuation of the symmetric +/- 50 deg. rocking profile from the previous week. On day of year 233 (2020-08-20) at 00:49 there is a 10 minute freeze observation during which an updated symmetric +/- 50 deg. rocking profile is loaded. This continues until the end of the week. Note that positive rock angles are south, and negative angles are north. (updated: 29-Jul-2020)

This utility allows you to view Fermi's observing timeline. It defaults to the current AO cycle, but you can also view past AO cycles, along with timelines showing a summary of the Targets of Opportunity (TOO), Automatic Re-pointing Requests (ARR), other pointed observations, and non-science periods. Explanations of the columns can be found in the glossary.

Pointed observations (like ToOs and ARRs) that interrupted the schedule are indicated in bold. Preliminary scheduled observations are indicated in italics.

Note: Updates to this page can be delayed by unexpected timeline changes. For information about on-going Target-of-Opportunity observations, check the Approved TOOs page.
