Cycle 18 Solicitation Amended

The Fermi Cycle 18 solicitation was amended on February 5 to clarify that the page limit for the Science/Technical/Management section of Phase-1 proposals is four pages for Regular proposals and six pages for Large proposals. These page limits include figures but not references. This is a change from Cycle 17 when the 4- and 6-page limits included references. As a reminder, the solicitation was amended on January 17 to change the proposal due date to March 5, 2025. Full details of the Fermi Cycle 18 solicitation can be found in Roses Appendix D.6

LAT Data Processing Restored

LAT data processing was restored over the weekend. It will take another day or more to finish processing the remaining backlog.

LAT Processing Delay

The LAT data processing pipeline is currently offline due to issues with its computing cluster. The satellite itself is functioning normally. At this time, we do not have an estimated timeline for repairs. The data server does not have any LAT data from after December 30, 2024, and there may be some gaps starting from December 25, 2024. Once the pipeline is restored, it will take several days to catch up and make the data available through the server and in the weekly files. We will provide an update by Monday or sooner if more information becomes available.

LAT Outage - Updated

On December 16, 2024, the LAT experienced a flight software misconfiguration, which put the instrument in an incorrect state. The instrument is safe and responding to commands during this pause in data collection. The spacecraft and GBM are operating normally. Reset and recovery efforts are underway, and we expect to resume data taking soon. Update: At around 19:00 UT on December 19, the LAT reset was completed, and data collection resumed. LAT has returned to normal operations. The resulting data outage lasted 3.3 days. We thank the LAT Operations Team and the Fermi Flight Operations Team for their hard work in returning LAT to science data collection.
