MW 854

Mission Week 854 begins with a continuation of the -50 deg. modified sine profile from the previous week. Then, on DOY 284 (2024-10-10) at 01:16 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 5686s to 5688s. Note that positive rock angles are south, and negative rock angles are north. (updated: 04-Oct-2024)

MW 855

Mission Week 855 begins with a continuation of the -50 deg. modified sine profile from the previous week. Then, on DOY 291 (2024-10-17) at 00:50 UT a 10-minute freeze observation occurs during which a -50 deg. modified sine profile is loaded. Next, on DOY 295 (2024-10-21) at 15:25 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 5687s to 5686s. Note that positive rock angles are south, and negative rock angles are north. (updated: 25-Sep-2024)

MW 856

Mission Week 856 begins with a continuation of the asymmetric -50/+60 deg. profile from the previous week. Then, on DOY 298 (2024-10-24) at 00:15 UT a 10-minute freeze observation occurs during which an asymmetric -50/+60 deg. profile is loaded. Next, on DOY 299 (2024-10-25) 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 DECREASED from 5686s to 5685s. Note that positive rock angles are south, and negative rock angles are north. (updated: 02-OCT-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.

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