Some very nice videos and images

Hi Salvador,  

Your blog is looking very nice. And the video for the 23rd is stable with only a little motion.

I wonder though if there might be a way to use your images to count sunspots?

Not everyone has access to H-alpha (and perhaps Calcium II) filters, and
some folks currently working with solar images are using video and then
running programs like Registax  http://www.astronomie.be/registax/  to
select out the best contrast image. Here's how Dan Vidican (VIDD) does it:
http://www.aavso.org/sites/default/files/solar_bulletin/AAVSO_SB_2013_11.pdf

Jan Alvestad (SDOH) also submits monthly data from a computer program he
developed to count groups and sunspots from the SDO/HMI daily SDO satellite
images at Stanford: http://jsoc.stanford.edu/   This may be the most
promising method if there were a set of computer algorithms available for
those who capture white light CCD images, and perhaps H-alpha at the same
time.  As the imaging methods would have to be somewhat standardized to be
processed by the computer, and the outcome would be group and sunspot
counts, which could then be put into the SunEntry database.
