Daily Coronal Images Available from NSO/SP ftp Site (1Dec92)
(from NSO, NOAO Newsletter No. 32, 1 December 1992)

Full-disk coronal maps in Fe XIV and Ca XV made using data from the
Emission- Line Coronal Photometer at the NSO/SP Evans Solar Facility
are now available on Internet directly from NSO/SP as well as from
NOAO. An article describing the maps and the procedure for obtaining
them from the Tucson NOAO ftp site was published in the 1 June 1992
issue of this Newsletter on page 29. The procedure for obtaining them
from NSO/SP is given below.

Map file names are ion.mmddyyl, where ion is fexiv or caxv, mm is the
month, dd is the day, yy is the year and l is the limb from which the
data are taken (e or w).
