Amateur Activity in Variable Stars field
I collaborate with several institutions sending my reports of variable star visual observations: LIADA Variable Star Section, REA from Brazil, AAVSO, VSNET, AFOEV.
One of my articles about the history of variable star observing in Latin America was published in MIRA from AVE (Spain) http://www.uv.es/~regalado/mira/mira1/106.html
