Abstract

A DETAILED knowledge of the structure of solar noise storm bursts is essential for a theoretical treatment and understanding of the phenomenon. Different methods of observation have been tried in order to secure information on important physical quantities of storm bursts. In this communication some preliminary results are reported from an analysis of highspeed records which were taken with a receiver containing two channels centred at 199 Mc./sec. and 200.5 Me./sec. (band-width: 0.3 Mc./sec., time constant 0.01 sec., and noise factor about 4). Records were taken with a double-channel Brush recorder at paper-speeds of 5, 25 and 125 mm./sec. Records have been obtained since February of this year during most noise storm periods.
