Solar Images from the EUV and Soft X-ray Spectroheliographs on OSO-7
Listed in NASA Earthdata CMR
Two of the six instruments on board the OSO-7 were an EUV spectroheliograph (Neupert, Thames, and Chapman 1974) and a Hard X-ray Spectrometer (Datlowe, Elcan, and Hudson 1974).
Description
The spectroheliograph provided 5'x5' rasters (spectroheliograms) over the active region at four wavelengths every 61 s, with a pixel size of 12' x 20'. The wavelength of the EUV spectroheliogram could be adjusted from 17.0nm - 40.0nm.
The solar image was usually severely undersampled, i.e., only about 1/3 of the solar image was scanned. The instrument could co-record H-alpha spectroheliograms with a wide 0.086 nm bandpass, blueshifted 0.016 nm from the H-alpha rest wavelength through the same aperture as the EUV spectroheliograms. The X-ray instrument provided simultaneous spectroheliograms in two bandpasses: 0.502nm - 0.795nm, and 0.795nm - 0.951nm.

The instrument also contained an x-ray polarimeter that recorded the integral solar emission in the 15-60 keV band with 20 seconds temporal resolution (Nakada, Neupert, and Thomas 1974). This data set consists of data obtained with the GSFC Solar EUV and Soft X-ray Spectroheliograph on OSO-7. The dataset consists of Large Raster Data, Small Raster Data, solar EUV spectra of selected regions, plots of X-ray polarimeter data, synoptic maps at 28.4 nm large raster data, and planning documents, user guides, and calibration reports.
The large and small raster spectroheliograms are available in digital form.
