Es-Score
Composite score 0–100 estimating the likelihood of a Sporadic-E opening.
≥70 Strong opening likely
45–69 Moderate — 6m openings probable
20–44 Low — mainly local propagation
<20 No significant Es expected
--
foEs MAX (MHz)
highest ionosonde
foEs — Critical Sporadic-E Frequency
≥88 MHz FM-DX possible
≥50 MHz 6m Es opening
<50 MHz Normal / low Es
