Hello all, Hereby the complete references I talked about in an earlier mail (I did not have them at hand at that time), about the realation between solar activity and meteor activity. -Marco - Lindblad B.A., 1978: Meteor radar rates, geomagnetic activity and solar wind sector structure. Nature 273, 732-734 - Jenniskens P., 1994: Meteor stream activity I. The Annual streams. Astronomy & Astrophysics 287, 990-1013.
