1st Update

In order to get used to solarsoft and line of sight magenetograms, I picked out 6 past solar flares and created videos (best viewed in HD) of the evolving magnetic fields as the flares occurred.  I downloaded the data from virtualsolar.org and wrote an IDL proceedure to batch process the .fits files into jpegs, then finally ran the images together using Adobe Lightroom.

Flare 1 – X2.1 – 6/9/2011 @ 22:16 UT

Observations
– Hook of netural polarity extends into positive polarity spot at [280,140]
– Flare visible at 22:16 as breif flashes of embedded opposing polarities

Flare 2 – X1.8 – 7/9/2011 @ 22:23 UT


Observations
– Negative polarity arc encircles a smaller negative region at [500,130] which reconnects with positive region at 22:35 UT (12 mintues after flare..)

Flare 3 – X5.4 – 7/3/2011 @ 00:24 UT AND X1.3 @ 01:14 UT


Observations
-Much bigger region with polarities more overlapping
– Negative polarity spot in top left appears to have noise/instability throughout the video
– 2 Curves of positive/neutral polarity present in negative spot at [-230,370]

Flare 4 – M5.6 – 2/7/2012 @ 10:52 UT


Observations

-Hook feature with flow from East to West at around [-80,-320 ] in vicinity of flare site (flare not visible in video)
-Emerging negative polarity at [-180, -350]

Flare 5 – X1.4 – 12/7/2012 @ 16:52 UT


Observations

– Negative polarity hook/spiral extends into centre of positive polarity spot on right
– Negative/netural polarity at centre of second positive spot
– Dip in positive polarity at 16:46, 6 mintues prior to flare

Flare 6 – M6.5 – 11/4/2013 @ 07:16 UT

Observations
– Very small quickly emerging and dissolving flows of negative polarity between two spots
