SOLAR FILAMENTS: Today, amateur astronomers around the world are monitoring a pair of dark magnetic filaments on the sun. Rogerio Marcon sends this composite image from his backyard observatory in Campinas, Brasil: (image not included in post)

The largest filament, which is curling over the sun's northeastern limb, stretches at least 50,000 km from end to end. SOHO has been monitoring the plasma-filled behemoth for more than three days: movie. How long can this filament hold itself up? If it collapses and hits the stellar surface, the impact could produce a powerful Hyder flare. Readers with solar telescopes are encouraged to monitor developments.


We had a similar filament in February. That one collapsed with no ill effect that we know of. There is speculation around a link between solar activity and geological events such as earthquakes which is to this date unsubstantiated. The last filament did collapse (Feb 25) in near proximity to the Chilean earthquake (Feb 27) which is interesting, but no direct relationship has been established.

Note: These filaments observed today are significantly smaller than the great filament in late February.

In any event, the sun had been so quiet that it is refreshing to see it waking up again. Let's keep an eye on these filaments and hope that the only thing we see from them when they do collapse is some beautiful aurora!

whoops, sorry. Did not see any under Fragile Earth.

Mods, feel free to delete this thread if it is redundant.
