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.
