Summary[edit]

Description

Today's observations show some interesting activity from Active Region 11613 that occurred on the 18th and 19th of September. Streams of plasma originating from the bright (the colors are reversed so the darkest regions have the greatest intensity) central region are seen sweeping from left to right across the field. This action plays out over about 17 hours and is condensed in the gif animation (see link below). As flux wells up from beneath the surface, the overlying collection of magnetic field lines (arcade) is pushed higher into the corona, where the rising closed loops meet field lines open into space or elsewhere on the sun. This spurs magnetic reconnection between the closed and open fields, allowing plasma to jet out along the open field lines, and a series of these events produces the sweeping motion. A schematic of this model can be found here: http://tinyurl.com/cbpy2fr. And since flux springs continuously during this period (see HMI magnetogram movie in original post, link below), this process happens several times with a few hours between each event.

Hinode is a Japanese mission developed and launched by ISAS/JAXA, with NAOJ as domestic partner and NASA and STFC (UK) as international partners. It is operated by these agencies in co-operation with ESA and the NSC (Norway).
