Report

O Mês Mundial da Astronomia 2012, começou com o SunDay esta tarde, dia 1 de Abril, No Observatório Astronómico de Gaia (OAPB). O OAPB em parceria com a CAUP realizaram uma observação solar, que apesar de nuvens incómodas terem ameaçado a realização do evento, foi possível levar a bom porto as actividades. As pessoas aderiram mesmo assim e tiveram a oportunidade de ver o Sol como nunca viram, através de telescópios preparados para a observação solar que mostrava aos interessados as manchas solares e filamentos da sua superfície bem como algumas protuberâncias no bordo do Sol através do telescópio H-alfa.

Paralelamente à actividade que decorria no observatório, estava patente ao público, no átrio de entrada do parque biológico de Gaia, uma exposição de relógios de Sol de vários tipos e modelos, gentilmente cedida por PEDRO GOMES ALMEIDA, que foi o construtor desses relógios. Segue-se uma pequena mostra fotográfica dessa exposição.
