  1. The bursts in emission and absorption as a fine structure of Type IV bursts  V.N. Melnik (1), A.A. Konovalenko(1), A.I. Brazhenko (2), H. Rucker (3), V.V. Dorovskyy(1), E.P. Abranin(1), A.Lecacheux(3), A.S.

  2. Type IV burst during passing of active region N 249 through solar disk drift rates of fiber burst

  3. duration radio fluxes

  4. CONCLUSIONS • fiber bursts are similar to usual Type III bursts • sources of fiber bursts move through plasma more uniform than average coronal plasma • electron beams propagate towards and outwards the Sun and their linear velocity is about 0.3 c • density of electron beams, which are responsible for fiber bursts is approximately the same
