NSO Daily Images Available by FTP from Solar...(1Sep92)
Terrestrial Dispatch
(from NSO, NOAO Newsletter No. 31, 1 September 1992)

Sac Peak coronal scans and Ca K images, and Kitt Peak magnetograms and
He I 10830 A images are available as "GIF" plot images through the Solar
Terrestrial Dispatch (STD). STD, in cooperation with the University of
Lethbridge, is a supplier of time-critical solar and geophysical
information to the scientific and public community. Numerous solar
services are available through the Internet to those who require solar
and/or geophysical information. An anonymous FTP service has been set
up to provide solar-related services to the professional scientific
community from the site "xi.uleth.ca" (IP number 142.66.3.29). To
login, use the username "anonymous". At the "password:" prompt, use
your e-mail address.

The coronal green Fe XIV (5303 A) and red Fe X (6374 A) lines, as
measured by the Sac Peak Emission Line Coronal Photometer, are
available in the directory "pub/solar/Corona". The file names are of
the form "corMMDD.gif" where MM and DD represent the month and day of
the observations. The file "00-index.txt" contains a full description
of the images. The data are taken with a photomultiplier at 0.15 solar
radii above the solar limb through a 1.1 arcminute aperture.

The Kitt Peak magnetograms, He I 10830 A images, and Sac Peak Ca K
images are available in the directory "pub/solar/Images". The file
names are of the form "YYMMDDxn.gif" where x is h for the Helium
images, d for the magnetograms, and k for the Calcium K images. n is a
sequence number for the day. Here also, the file "00-index.txt"
contains a full description of the images.

Other GIF images and services are available; e.g. H and white light
images, GOES x-ray time series... Questions should be directed to:
oler@rho.uleth.ca, or: coler@solar.stanford.edu.
