Radio signal SHGb02+14a is a source and a candidate in the Search for Extra-Terrestrial Intelligence (SETI), discovered on March 2003 by SETI@home and announced in New Scientist on September 1, 2004.[1]

The source was observed three times at a frequency of about 1420 MHz,[2] which is expected to be a frequency used by extraterrestrials due to its proximity to one of the main frequencies at which hydrogen absorbs and radiates photons.
