  • MW 960: Mission Week 960 begins with a continuation of the asymmetric -50/+60 deg. profile from the previous week. Then, on DOY 295 (2026-10-22) at 01:31 UT a 10-minute freeze observation occurs during which an asymmetric -50/+60 deg. profile is loaded. Next, on DOY 296 (2026-10-23) at 02:40 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 DECREASED from 5664s to 5663s. Note that positive rock angles are south, and negative rock angles are north. (updated: 16-Oct-2026)

    MW 961: Mission Week 961 begins with a continuation of the symmetric +/-50 deg. profile from the previous week. Then, on DOY 302 (2026-10-29) at 01:51 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 5663s orbital period. Note that positive rock angles are south, and negative rock angles are north. (updated: 21-Oct-2026)

    MW 962: Mission Week 962 begins with a continuation of the symmetric +/-50 deg. profile from the previous week. Then, on DOY 309 (2026-11-5) at 00:25 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 DECREASED from 5663s to 5662s. Note that positive rock angles are south, and negative rock angles are north. (updated: 14-Oct-2026)

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. If you have JavaScript enabled on your browser, you may click on column names to sort by that column.
