โœฆ Synopsis

The locations of flarcs and chromospheric absorption features on May 21 and 23, 1967, are compared with a series of ]-Ia magnetograms. Each of the four major flares included in the study developcd as double emission ribbons lying at positions of steep field gradient on opposite sides of the boundary between regions of opposite magnetic polarity. At certain stages, the flare outlines followed closcly thc isogauss contours of the longitudinal field. A fluctuating field of 75 gauss was measurcd directly in the importance two flare of May 21. Modifications in the magnetic structure of the active region followed the flares of May 23.

We have measured the longitudinal component, Bll, of the magnetic field in quiescent prominences and obtained a relationship between BII and 0, where 0 is the angle between the long axis of the prominence and the north-s0uth direction on the sun. From this relationship we deduce a distribution funct
