Solar Ultraviolet Data from Orbiting Solar Observatory (OSO 8) Space MissionEntry ID: OSO-8-spectro-level1
Abstract: The LPSP multichannel High Resolution UV and visible spectometer was launched
June 21, 1975 and was in operation until September 30, 1978 with 6 channels
covering the most intense optically thick chromospheric lines (H and K CaII,
h and k MgII, Lymann alpha and Lymann beta HI)
The imaging system is a cassegranian telescope, with a collecting area of
170 cm2 and an aperture f/16.
The solar image ... can be scanned by moving the secondary mirror in azimuth and
elevation. Each step increment is either 1' or .5'.
The size of the raster in azimuth and elevation is chosen between 1' to 64'
by binary increments.
The slit defines the focus of the telescope and is formed of two parts :
- a narrow one of 1'x60' which optimizes the spectrometer resolution
- a large one of 6'x6'
a rotating disk actuated by a stepping motor allows the selection of several
The dispersing system is a 6 channel polychromator of the Czerny-Turner type.
The main dispersor is a 1200 grooves (1/mm) plane grating. The scan in
wavelength is performed by rotation of the grating.
Raw data are on 1600 bpi magnetic tapes and saved on 6250 bpi tapes, all
created on CDC computer running NOS-BE system.
The data will be restore in the next years and will be then completely available
Nevertheless, for any urgent need, please contact data Center.
