Full-Disk Images (jpg file, 512x512,1024x1024,2048x2048 pixels)

2010 2011 2012 2013 2014 2015 2016 2017
The image orientation is celestial north at the top and west to the right.
The files are named as "mov_{000,050,080,350}_{int,dop}_nnnn.jpg" or "raw_{000,050,080,350}_{int,dop}_YYYYMMDD_hhmmss.jpg", where "mov" indicates an image of 512x512 pixels for MPEG movie and "raw" indicates an image of 1024x1024 pixels.
Numbers {000,050,080,350} indicate images of Hα center (6563Å), 6563±0.5Å, 6563±0.8Å, and 6563+3.5Å respectively and {int,dop} indicates intensity or Doppler images.
nnnn is the serial number, YYYYMMDD and hhmmss are the date and time (UT) of observation.
The "today" directory includes a set of 2048x2048-pixel best images.

Full-Disk Movies (MPEG and Javascript movie, 512x512 pixels)

2010 2011 2012 2013 2014 2015 2016 2017
The files are named as "YYYYMMDD_{000,050,080,350}_{int,dop}.mpeg".
YYYYMMDD is the date of obsrvation. {000,050,080,350} and {int,dop} have the same meanings of full-disk images
jsmovie_sftha{000,050}_YYYYMMDD.html is Javascript movie.

Full-Disk Images (FITS-format data)

2010 2011 2012 2013 2014 2015 2016 2017
The files are named as "SFTH_wl_YYYYMMDD_hhmmss.fts", where wl indicates the following image.
  • rlp00 : Hα center for long exposure
  • rsp00 : Hα center for short exposure
  • rsm05 : Hα−0.5Å for short exposure
  • rsp05 : Hα+0.5Å for short exposure
  • rsm08 : Hα−0.8Å for short exposure
  • rsp08 : Hα+0.8Å for short exposure
  • rsp35 : Hα+3.5Å for short exposure
  • dlxxx,dsxxx : dark data for long and short exposures
  • flp00, fsp00 : flat data for long and short exposures of Hα center
  • fsm05, fsp05, fsm08, fsp08, fsp35 : flat data for Hα−0.5Å, Hα+0.5Å, Hα−0.8Å, Hα+0.8Å, and Hα+3.5Å, respectively
YYYYMMDD and hhmmss are the date and time (UT) of observation.
