It's with deep sadness that I share here the news that Giovanni Sostero has passed, after being striken by a heart attack.
Giovanni, class 1964, was very active in the research concerning minor bodies of our solar system, variable stars and supernovae.
He is the discoverer of eleven supernovae and one nova.
My personal condolescences go to this family and his friends.
