The Astronomer's Telegram (ATel) is an internet-based short-notice publication service for quickly disseminating information on new astronomical observations.[1][2] Examples include gamma-ray bursts,[3][4] gravitational microlensing, supernovae, novae, or X-ray transients, but there are no restrictions on content matter. Telegrams are available instantly on the service's website, and distributed to subscribers via email digest within 24 hours.[citation needed]
The Astronomer's Telegram was launched on 17 December 1997 by Robert E. Rutledge[5][6] with the goal of rapidly (<1 s) sharing information of interest to astronomers. Telegrams are sent out daily by email, but especially time sensitive events can be transmitted instantly.[7] Since 2013, information is also broadcast over Twitter and Facebook.[citation needed]
To publish, astronomers request credentials. Credentials are issued to professional astronomers and graduate students, after verification by personal contact.[6] Once credentials have been supplied and telegrams authorized, astronomers can publish telegrams directly, with no further editing.[8]
As of August 2019, over 13000 telegrams have been published.
