Fermi Science Support Center
There will be a network outage, Sunday, April 26 from 13:00 EDT - Monday April 27 01:00 EDT. All services, web sites, and systems that require access to the internet will be affected by this work.

The Fermi Science Support Center (FSSC) runs the guest investigator program, creates and maintains the mission time line, provides analysis tools for the scientific community, and archives and serves the Fermi data. This web site is the portal to Fermi for all guest investigators.

This view shows the entire sky at energies greater than 1 GeV based on five years of data from the LAT instrument on NASA's Fermi Gamma-ray Space Telescope. Brighter colors indicate brighter gamma-ray sources.

Look into the "Resources" section for finding schedules, publications, useful links etc. The "Proposals" section is where you will be able to find the relevant information and tools to prepare and submit proposals for guest investigator projects. At "Data" you will be able to access the Fermi databases and find the software to analyse them. Address all questions and requests to the helpdesk in "Help".

Fermi Observations for MW 360

Mission Week 360 starts with a 10 minute pointed "freeze" observation during which the updated survey profile for this week is loaded. That profile, using the regular 50 degree rock angle, then continues for the remainder of the week. Between 2015/113:14:02:00 and 2015/113:15:35:00 LAT calibrations will be performed and this is marked as "Calibration Downtime" in the timeline. Between 2015/113:16:37:00 and 2015/113:18:56 there are two pointed observations toward the Galactic Center to allow for routine monitoring of the star tracker alignment.

Aperture Photometry Light Curves for LAT 3FGL Catalog Sources

Aperture photometry light curves of all 3FGL sources with 30 day time resolution, together with power spectra of these, are now available. These will normally be updated weekly. In addition, results of an automatic search for flaring 3FGL sources are also provided with weekly updates. Light curves and power spectra are here. Flaring sources are here.
