Observations of AR 5395 in Coronal Emission Lines.

摘要

Observations of AR 5395 and subsequent rotations were obtained with the NSO/SP Emission-Line Coronal Photometer. Observations in Fe XIV 5303A (2MK), Ca XV 5694A (< 3MK), and Fe X 6374A (1MK) were obtained at radii between 1.13 and 1.15. The data are corrected in real time for the sky background and reduced to absolute intensities in millionths of the brightness of the center of the disk at the local wavelength.
