MW 864

Mission Week 864 begins with a continuation of the symmetric +/-50 deg. profile from the previous week. Then, on DOY 354 (2024-12-19) at 01:30 UT a 10-minute freeze observation occurs during which a symmetric +/-50 deg. profile is loaded. This profile continues until the end of the mission week. The survey repeat period is based on a 5682s orbital period. Note that positive rock angles are south, and negative rock angles are north. (updated: 17-Dec-2024)

MW 865

Mission Week 865 begins with a continuation of the symmetric +/-50 deg. profile from the previous week. Then, on DOY 361 (2024-12-26) at 00:51 UT a 10-minute freeze observation occurs during which a symmetric +/-50 deg. profile is loaded. Next, on DOY 365 (2024-12-30) at 18:29 UT a 10-minute freeze observation occurs during which an asymmetric -50/+60 deg. profile is loaded. This profile continues until the end of the mission week. The survey repeat period DECREASED from 5682s to 5681s. Note that positive rock angles are south, and negative rock angles are north. (updated: 04-Dec-2024)

MW 866

Mission Week 866 begins with a continuation of the asymmetric -50/+60 deg. profile from the previous week. Then, on DOY 2 (2025-1-2) at 19:01 UT a 10-minute freeze observation occurs during which a -50 deg. modified sine profile is loaded. This profile continues until the end of the mission week. The survey repeat period INCREASED from 5681s to 5682s. Note that positive rock angles are south, and negative rock angles are north. (updated: 11-Dec-2024)

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.
