BLC1
BLC1 seinalea inteligentzia estralurtarra bilatzeko SETI programaren irrati seinale bat da. Seinale honen harrerari buruzko albistea 2020ko abenduan iragarri zen, eta, dirudienez, Proxima Centauri izarretik etorriko litzateke. Seinalea 982,002 MHz-ko frekuentzian igorri zen[1], eta urdinerako lerrakuntza bat du, Proxima B-ren mugimenduak eragindako Doppler efektuarekin bat datorrena, Proxima Centauri sistemaren exoplanetetako bat[2].
Seinalea 3 orduz detektatu zen Breakthrough Ekimenak Australiako Parkes Behatokian 2019ko apirila eta maiatza bitartean egindako behaketa batean[3]. 2020ko abenduaren amaierara arte, ondorengo behaketek ez dute arrakastarik izan seinalea berriro detektatzeko, seinale hori sinadura teknologiko bat dela baieztatzeko beharrezko urratsa baita.
