Current foF2 Plots

These are graphs of autoscaled foF2 against monthly predicted foF2 values. These values are based on the automated interpretation of ionograms received each hour.

Current foF2 Plot


  • White solid line indicates monthly predicted foF2.
  • White dashed line indicates monthly predicted foF2 +/- 30%.
  • Red solid line indicates hourly observed (autoscaled) foF2 from that station.
  • Yellow solid line indicates sporadic E (foEs).
  • Blue squares indicates hourly autoscaled foF1 from that station.
