National Solar Observatory (NSO) Sacramento Peak Fe XIV and Ca XV Coronal Maps

Listed in NASA Earthdata CMR

The National Solar Observatory has made data accessible on-line via the networks.

Description

Two databases containing the National Solar Observatory/Sacramento Peak Fe XIV 530.3 nm and Ca XV 569.4 nm coronal maps are accessible in separate subdirectories. The subdirectory names are the names of the ions, and each file name includes the ion, date and limb of observation.

For example, the Fe XIV coronal maps for Jan 23, 1991 are labeled 'FeXIV/fexiv.012391.E' and 'FeXIV/fexiv.012391.W'. Each ASCII file contains 3 lines of header followed by 122 lines of data. The data are intensities in millionths of the brightness of the solar disk at 0.15 Ro above the solar surface (limb).

A value of -1.0 implies either background (the sky), or two or more consecutive days of missing data in the Ca XV maps. The intensities are arranged in 61 line pairs of 29 data points (15 in the first line and 14 in the second line). The data form a 61x29 array with the first column as the East Limb and the 29th column as the West limb.

The first row represents the North pole and the 61st row represents the South Pole. The data are available from " ftp://ftp.nso.edu/corona.maps/" Current coronal FE XIV and Ca XV are available from: "sunspot.noao.edu/nsosp/data/latest_solar_images.html"
