in reference to earth front / back and surounding space. probably spread about less than 100ms. And the radio burst arrives the same moment any visible phenomena appear ( at 300e3km/s ). The particle stream ( 400..800km/s) takes a bit longer( ~50..100hours) and then interacts with the earth magnetic field. uwe _______________________________________________ questions mailing list [email protected] https://lists.ntp.isc.org/mailman/listinfo/questions
