flare and surge, AR11762, 02 June 2013
C1.8 flare and surge time lapse movie
A minor C class flare in AR11762 on 02 June 2013 resulted in a series of surges reaching out some 45,000 kms.
Seeing was poor with passing high clouds, but this animation made up of -0.5A blue-wing filtergrams clearly shows
the extensive surge activity over 18 minutes.  Several Ellerman Bombs can also be seen to brighten, then fade.

Vertical jet-like structure in AR11429 spot cluster, 03 March 2012.  The bright jets are likely surges produced by small sub-flares that are clearly visible at  their bases.
AR11429 was putting on a show before even rounding the eastern limb into view with an X-class flare.  Since then there have been daily flaring associated with the
spots and plage, C, M and X class flares.

Sunspot with light bridge and pores in AR11289, and emerging active region to far right.  The 0.8A Daystar filter is intended pretty exclusively
for solar prominence photography, however, these photos demonstrate that chromospheric features on the disk can be imaged as well.
Center wavelength 6563A, -0.5A [blue wing] and +0.5A [red wing]

Equipment:  Lunt LS50F filter on a 400mm FL ED refractor used primarily for full disk viewing and imaging.  Daystar ION 0.8 Angstrom
filter with 100mm aperture energy rejection filter on a 102ED f/7 refractor with 4x telecentric -- system operates at f/28.  Cameras;
DMK21 and DMK41 digital video cameras for live viewing and imaging, and Watec analog video camera primarily for full disk viewing.
