MUFs stayed near predicted monthly values for high latitude regions during this day. Similar ionospheric support is expected for UT day 19 November. Further MUF depressions may be observed through UT days 20 and 21 November due to expected enhancements in geomagnetic activity levels on these days.

Geomagnetic Latitude Ranges:

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