Further fadeouts are likely on daylight HF circuits. With respect to ionospheric frequencies of support, HF radio communication conditions on UT day 22-Feb were normal. HF radio communication conditions are expected to be mostly normal over 23-24 Feb. Moderately degraded HF conditions for middle to high latitudes are expected for 25-Feb.

Geomagnetic Latitude Ranges:

  • Low: 0-20 degrees
  • Middle: 20-60 degrees
  • High: 60-90 degrees
