Solar Activity Alerts

This page provides solar activity "alerts." Such alerts are issued when solar activity is likely to have a reasonable effect on Earth's geometric conditions. This can and will often result in diminished quality of radio wave propagation for ham operators on various bands. On rare occasions it can be favorable on band quality. Solar activity alerts also are good indicators that there may be good aurora (Northern Lights) activity during hours of darkness of the specified period.

This is a public service through W9SBU, Weyauwega, WI and should not be considered an official statement from ARES or Waupaca County.
