Nearby 4FGL sources

Fermi sources are shown within a 5 deg radius from the alert best-fit position. Sources contained within the error circle of the alert are highlighted in color. For sources with a known association, "Search Simbad" returns an identifier query using the association name listed (note that in many cases the association name is not resolved by Simbad). If no association is listed, return a radial search 0.3 deg around the Fermi source position.

Interactive skymap

The interactive window shows a background of the Fermi (color) skymap and markers for nearby sources in three HE catalogs: 4FGL, 3FHL, and 2WHSP. Other catalogs (2RXS and BZCat) plus a dynamic HiPS search in Simbad can be enabled from the layer control of the left. An additional Simbad search shows a selection of objects (detected in radio, X-rays, gamma-rays and/or galaxies) near the best fit position. The background sky can be changed to optical (Mellinger survey) from the radio buttons below the image.

Visibility

Visibility plots (elevation vs time) for four ground-based instruments over the next hours for the alert. Dark (light) bands indicate civil (astronomical) twilights for each site. Moon and sun elevations are also shown.

Swift visibility

Visibility conditions for Swift at the time of the report generation based on the distance of the alert position to the Sun and Moon. Red or green colors indicate if the position is observable (>23 deg away from the Moon and >47 away from the Sun).

Sun separation [deg]55.0 deg
Moon separation [deg]149.9 deg
