Latitude Band Date Low Middle High 05 Oct Fair Fair-poor Fair-poor 06 Oct Fair Fair-poor Poor 07 Oct Fair Fair-poor Fair-poor COMMENT: HF radio communication conditions on UT day 4-Oct were normal. HF radio communication conditions are expected to become degraded at all latitudes on 5-Oct due to an anticipated CME arrival, followed by several other CMEs. Due to this, a prolonged geomagnetic storm is expected over 5-7 Oct, such that HF radio conditions are expected to be degraded for this whole period.

Geomagnetic Latitude Ranges:

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