AR 5395:A MOTION OF THE DARK MATTER IN 2N FLARE ON 9 MARCH

On March 9,1989,a 2N flare erupted in AR5395 active regin(N32.E51) in the solar disc between 0220 UT and 0300 Unaccompanied by an M 1.8 X event, and after the maximun the dark matter moved and ejected evidently. From the analyses it is believed that the motion of the dark matter is caused by the flow of chromospheric matter along the direction of the weakening of the magnetic field under the action of the magnetic tension after the flare, the ejection results from the action of the lower magnetic field during the downward flow of the dark matter, and the sunspot penumbre may be the supplementary source of the flow and ejected matter.
