SHGb02+14a is an astronomical radio source and a candidate in the Search for Extra-Terrestrial Intelligence (SETI), discovered in March 2003 by SETI@home and announced in New Scientist on September 1, 2004.
==Observation== The source was originally detected by Oliver Voelker of Logpoint in Nuremberg, Germany and Nate Collins of Farin and Associates in Wisconsin, USA using the giant Arecibo Telescope in Puerto Rico. It was observed three times (for a total of about one minute) at a frequency of about 1420 MHz, one of the frequencies in the waterhole region, which is theorized to be a good candidate for frequencies used by extraterrestrial intelligence to broadcast contact signals.
Discovered by embedding cosine similarity (sentence-transformers MiniLM, 384-dim).
