Sun Rotation - SEK El Castillo
27/November/201911-12 yr-55 students
The International School SEK El Castillo visited us to make a scientific experience. They came really well prepared to make a scientific case about the Sun, how long it takes to a black spot to move all around the Sun? What a pity we had a very limited time to finish well the scientific experience. Hopefully, next time, Madrid traffic jumps are better.

Anyway, clouds allowed us to watch (well protected) the Sun, thanks SOHO for this great images! With the Solar filter glasses, the Sun looks smaller than without them, does not it?
