Active Region Flares Due to Magnetic Reconnection
|
The rapid emergence of AR 12665 significantly increased solar activity last week. One of the side effects of the new active region is the disturbance it caused in the neighborhood. Everything around the active region wants to connect with it. The popular active region launched several moderate flares and changed rapidly while it crossed the solar disk. This movie shows the peak of a C1.2 flare. Complex flows are seen flowing away from a few bright loops in the active region.
Hinode XRT observed the active region using a flare watch program. When a flare was
detected, the telescope began taking images in a thicker filter (med_Be) along with a
thinner filter (thin_Be). The thin_Be image saturate while the med_Be don't. We combine
the images to show the really hot, bright core of the flare with the "cool" plasma around it.
