observations with the NASA Neil Gehrels Swift Observatory and the
Ultraviolet Optical Telescope. 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).</description><source format="bibcode">2004ApJ...611.1005G</source><referenceURL>http://dc.g-vo.org/std/gcn-swift-uvot/swift/info</referenceURL><contentLevel>Research</contentLevel></content><rights>public</rights><capability standardID="ivo://ivoa.net/std/voevent"><description>Fermi UV followup events including a postage stamp image.</description><interface role="std" standardID="ivo://ivoa.net/std/voevent#acc-kafka" xsi:type="voe:StreamEndpoint"><accessURL use="full">x-kafka://kafka.gcn.nasa.gov?topic=gcn.classic.voevent.SWIFT_UVOT_DBURST</accessURL></interface></capability><capability standardID="ivo://ivoa.net/std/voevent"><description>Fermi UV followup events including a postage stamp image, after ground
