Description
Doppler shifts of the solar Fe line 630.15 nm relative to the
terrestrial O2 line 630.2 nm were determined at many positions on the
solar disk to investigate the rotation of the solar plasma and locate
large-scale plasma motions. The spectrum was measured by a self-scanning
linear photodiode array with 128 diodes; and average rotation velocity
of (2.881 plus or minus 0.027) microrad/s was found at the solar equator
in September 1978, and large-scale velocity pattern occurred between
plus 40 and minus 30 deg in latitude with a period of 45 deg in
longitude during Sept. 6 to 13, 1978.
