An extreme close-up of NOAA 12177 recorded on October 2, 2014 at Big Bear Solar Observatory using the 1.6 meter New Solar Telescope (NST) and narrow band Fabry-Perot filter (.08A) centered on the hydrogen alpha bandpass. In my interpretation, the contrast has been increased and the image colorized and cropped to enhance visibility of the chromospheric structures.
