The IVOA VOEvent Working Group announces a workshop, the fourth of the series, to be held at the UCO/Lick Observatory at UC Santa Cruz, April 26-30, 2009

The astronomical time domain ranges from solar physics and solar system objects to objects and processes at galactic and cosmological distances. Transients arrive via electromagnetic radiation, gravitational waves, neutrinos and other particles. Discoveries are made via spacecraft and by ground-based surveys, through automatic pipelines and the Virtual Observatory, with robotic telescopes and by the human eye. A strong interdisciplinary agenda will engage the emerging information infrastructure for astronomical transient events and their rapid follow-up.

Session themes will include:

• Connecting a robotic telescope to an event stream
• Real-time mining of event streams
• Event streams: Catalina, OGLE, MOA
• BoF for event providers: LOFAR, Skymapper, GCN etc
• Event authoring and real-time dissemination
