Giovanni Sostero (18 March 1964 – 6 December 2012) was an Italian amateur astronomer. He was one of the leading members of the Associazione Friulana di Astronomia e Meteorologia (Friuli, Italy).[1] He was an honorary member of the Astronomical Observatory of Visnjan (Croatia), too.

Sostero was very active as a public out-reacher and has published some scientific works in professional astronomical journals. He had over 1880 NASA ADS citations for his work.[1] His main research fields were the minor bodies of the Solar System (asteroids and comets) and variable stars (symbiotic stars and supernovae). In particular, he discovered several supernovae: 2009jp, 2008ae, 2008F, 2007cl, 2006br, 2006bm, 2006H, 2006B, 2005ly, 2005kz, 2005kc.[2] In 2000 he co-discovered a nova in the galaxy M31.[3]

The asteroid 9878 Sostero (1994 FQ) was named after him.

He died on 6 December 2012[4] due to the complications of a heart attack. He was 48 years old.[1]

The "Giovanni Sostero Award"[5][6][7] was created in 2013 and supported thereafter by Elettra - Sincrotrone Trieste to honor Sostero, formerly in charge of the soft x-ray metrology laboratory at the facility.
