MW 546

Mission Week 546 starts with a continuation of the modified sine rock profile from MW 545. On day 319 (Nov. 15) at 01:12 there is a 10 minute freeze observation during which a new modified sine profile with an amplitude of -52 degrees during orbit day is loaded. This profile continues until day 322 (Nov 18) 03:32 when a +/- 50 degree rock profile is loaded. This executes a single rock from +50 to -50 degrees. At 03:58 a -50 degree only rock profile is loaded. This continues until the end of the week. Note that positive rock angles are south, and negative angles are north. (updated: 24-Oct-2018)

MW 547

This timeline transitions from -50deg fixed rock profile to 2-sided rocking (+/-50deg) beginning with a 10minute freeze observation at 2018/330 16:41UT when the beta angle transitions above -10degrees (less than 10 degrees absolute value). The 2-sided rocking profile is used for the remainder of the mission week The beta angle range for this mission week is -12.9 to +3.23deg. (updated: 1-Nov-2018)

MW 548

Mission Week 548 starts with a continuation of the +-50 degree rocking profile that was active at the end of the previous week. On DOY 333 at 00:10, there is a 10-minute freeze observation during which an updated version of that profile is loaded. As the beta angle remains below 10 degrees, this rocking profile will be used for the remainder of the mission week. (updated: 7-Nov-2018)

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.
