Events should be reported within tens to of seconds to hours; expect about 3 events per week, where most events correspond to a gamma ray bursts, but other transients may occur. Streams giving localizations for gamma ray transients with follow-up characterization in the ultraviolet/optical including localization and images with their ground-processed data. The sequence includes a postage stamp image (SWIFT_UVOT_DBURST, SWIFT_UVOT_DBURST_PROC), finding charts (SWIFT_UVOT_FCHART,SWIFT_UVOT_FCHART_PROC), and localization acquired (SWIFT_UVOT_POS) or not acquired (SWIFT_UVOT_POS_NACK). 0/0-11 170[nm] 650[nm] 2004-11-20 2035-01-01 swift-UVOT VOEv x-kafka://kafka.gcn.nasa.gov?topic=gcn.classic.voevent.SWIFT_UVOT_DBURST KafkaInterface Fermi UV followup events including a postage stamp image. x-kafka://kafka.gcn.nasa.gov?topic=gcn.classic.voevent.SWIFT_UVOT_DBURST_PROC KafkaInterface Fermi UV followup events including a postage stamp image, after ground processing. x-kafka://kafka.gcn.nasa.gov?topic=gcn.classic.voevent.SWIFT_UVOT_FCHART KafkaInterface Fermi UV followup events including a finding chart. x-kafka://kafka.gcn.nasa.gov?topic=gcn.classic.voevent.SWIFT_UVOT_FCHART_PROC KafkaInterface Fermi UV followup events including a finding chart, after ground processing. x-kafka://kafka.gcn.nasa.gov?topic=gcn.classic.voevent.SWIFT_UVOT_POS KafkaInterface Fermi UV followup events where positions have been acquired. x-kafka://kafka.gcn.nasa.gov?topic=gcn.classic.voevent.SWIFT_UVOT_POS_NACK KafkaInterface Fermi UV followup events where positions have not been acquired. https://gcn.gsfc.nasa.gov/swift_grbs.html A browser-based archive of the events recorded.
