The time domain remains one of the the least explored areas in modern astronomy. In the near future the next generation of large synoptic sky surveys (Pan-STARRs, Skymapper, LSST) will probe the time dependent nature of the sky by detecting hundreds of thousands of astronomical transients (variable stars, asteroids, GRBs, lensing events). A global event distribution and follow-up network is required to characterize the nature of these transients.
For over a year the VOEventNet project has been in the process of implementing a transient event follow-up network which distributes crafted structured data packets called VOEvents. These packets have been designed to be general enough to contain metadata for transients seen at all wavelengths, yet interpretable by robotic telescope systems (which are already automatically responding with follow-up observations). The VOEventNet project currently has transient event follow-up with the Palomar 60 and 200in (Caltech), RAPTOR (LANL), PARITEL and KAIT (UCB) as well as UK telescopes.
VOEventNet transient event streams are publicly available. The subscription, publication and reception of VOEvents is implimented with a number of open source software clients. The software and details of how to receive streams of events are available from http://www.voeventnet.org. Current event streams include OGLE microlensing events, SDSS Supernovae, GCN GRBs, Raptor and Palomar-Quest optical transients. In the near future, many additional streams of VOEvents will be available, including optical transients from the ESSENCE, Planet and MOA projects, as well as those from UKIRT and JCMT telescopes. We also expect that transient event alerts will be available from Solar, X-ray and Radio telescopes.
