SOHO Ultraviolet Coronagraph Spectrometer Observing Plan



 

Duration 33 hrs; from 99.08.10 15:00 UT to 99.08.11 23:59 UT
UVCS pB FOV (14 x 14) arcsec^2
UVCS Slit FOV 30 arcsec (radial) x 30 arcmin (tangent to the limb) 
Position Angles from 0 to 360 degrees in steps of 15 degrees
Heliocentric Heights 1.7 1.8 1.9 2.1 2.4 2.7 (solar radii) 
Visible Light broad-band polarized brightness (pB) of the K corona 
Spectral Lines neutral hydrogen Lyman-alpha 1216 Ang, Lyman-beta 1025 Ang, and O VI 1032, 1037 Angs. 
Supporting SOHO Instruments LASCO/C2, visible light pB measurements (2 - 6 solar radii) 
Supporting Ground Experiements - SAO expedition in Syria (broad-band pB of the K corona at heliocentric heights: 1.1 - 2.5 solar radii)

- French-Czech observation from Bucharest GBO in Romania (visible light narrow-band spectroscopy of the Rayleigh emission from coronal neutral hydrogen)
