E já agora umas fotos da mancha 982, feitas com telescópios solares!

Atenção:
Nunca tente olhar directamente para o Sol, nem com binóculos ou telescópio.
Poderá causar lesões irreversiveis na vista ou mesmo cegueira.

Os telescópios utilizados para estas fotos são especiais para este tipo de
observação.
