AN ISOPHOTOMETRICAL STUDY OF WIGGLES IN THE SOLAR IRON LINES,
Abstract
Marked asymmetries are observed in the profiles of moderately strong and weak iron lines near the centre of the solar disk. These asymmetries are shown to vary strongly from point to point on the sun. The properties of the asymmetries are discussed. The observations show that large scale irregularities of the order of 100,000 km may be present in the solar photosphere. Comparison of simultaneous observation of lines of different intensity indicates that the lines are shifted relative to each others, in the sense that the stronger lines are shifted more to the red than the weaker ones. This difference between weak and moderately strong lines have been found in spectra obtained at two different observatories. If the difference in line shift between different lines is interpreted as doppler shift, velocities up to 1 km/sec are found. (Author)
