On Saturday April 18th, an immense Solar Coronal hole was pointed directly at earth. HF Conditions Suffered. Members still got out the weather being genuinely fine. Here are their briefings N6BLU: The absolute toughest conditions were had at the beginning of the clubs POTA today. Never has it taken so long to get that firstContinue reading “Amateur Radio Day POTA Haul”

Ionosphere Linked to Earthquakes
Could ionospheric disturbances influence earthquakes? Researchers at Kyoto University explored how disturbances in the ionosphere exert electrostatic forces within Earth’s crust. They found that such forces potentially contribute to the initiation of large earthquakes under specific conditions. The coincidence of strong solar flare activity with the 2024 Noto Peninsula earthquake supports the hypothesis that ionosphericContinue reading “Ionosphere Linked to Earthquakes”
Bruised Ionosphere
Conditions should improve by late tomorrow. We are experiencing the impact of a major solar event that began on January 19, 2026. While solar flux is high (generally good for DX), the atmosphere is extremely “noisy” and unstable due to a direct hit from a fast-moving Coronal Mass Ejection (CME). Impact on Ham Radio OperationsContinue reading “Bruised Ionosphere”
