Absorption Measurements

Cosmic noise absorption measurements at 30 MHz were made simultaneously on two antennas having different beam widths at London, Ontario(53 °N geomagnetic, L = 3.1), a subauroral zone station. The data show that absorption is caused by regions of ionization which exhibit marked spatial non-uniformity within the antenna beams, and which have horizontal extensions limited more toward the south than toward the north of the station. The measurements also indicate the presence of auroral ionization at all times of the day over London.
