I was dedicated to the search and study of supernovas since 1991.
Also to AGNs (Active Galactic Nucleus) of long period, such as Blazar, Galaxy Seyfert and Quasar,
I am a member and collaborator of the following international organizations.

AAVSO American Association of Variable Star Observers
VSNET Department of Astronomy, Kyushu University, Japan
LIADA La Liga Iberoamericana de Astronomía
CAA Centro Astronómico de Avila
ObSN Observadores de Supernovas

Sometimes I publish articles in the section "Distant Sparkles"
in the magazine "Tribune of Astronomy and Universe"

And monitor in the public observations in the museum
of the science of CosmoCaixa in Alcobendas (Madrid)
