Worth noticing
Its explanations connect K-index levels and solar flares to practical effects such as fading, absorption, and shortwave outages.

Field notes

The page separates shortwave conditions, VHF conditions, NOAA scales, historical measurements, solar imagery, and explanations into distinct sections. Its reference material gives practical context: it describes the K-index in three-hour intervals and explains how strong solar flares can disrupt shortwave signals on Earth's dayside. The captured extract shows these sections and their sources, but the live-value areas still display loading messages.
