Burst Analyser — BAT-XRT-UVOT light curves

We will be performing essential maintenance from 0900 BST (0800 UT) on June 18 2020. During this time we will be operating with reduced resiliency, however no significant downtime is expected. There may be a couple of brief (1-2 minute) interruptions to services during which web pages may take longer to respond. We apologise for any inconvenience this may cause.

This website contains BAT, XRT and UVOT fluxed light curves of all GRBs observed by Swift. The flux conversion is time-dependant and accounts for spectral evolution. See the online documentation for details

In January 2016 the Burst Analyser was modified to include a new plot: the observed flux density. This plot, which includes UVOT data when available, is the first plot on the individual target pages. See the online documentation for details.
