Sun Flares Unleash Radio Blackouts
4 Feb
Summary
- X1.5 solar flare caused strong radio blackouts, disrupting communication.
- Solar Cycle 25 is currently at solar maximum, increasing flare likelihood.
- Past storms in May 2024 and Nov 2025 caused significant economic losses.

A recent X1.5 solar flare caused significant radio blackouts, impacting high-frequency radio communication for approximately one hour, with disruptions primarily reported in Australia and New Zealand. Scientists attribute this event to Solar Cycle 25, which is currently at its solar maximum phase. This period often sees surges in activity, with forecasts indicating that strong solar events are expected to continue through 2026 and possibly into 2027.
This solar activity follows significant past events. In May 2024, a powerful solar storm, including an X8.7 flare, caused an estimated $1 billion in losses due to GPS disruptions for farm equipment and prompted a massive satellite migration. In November 2025, an X5.1 flare led to the cancellation of over 30 polar flights and a rocket launch delay due to radiation risks. These events highlight the potential impact of solar flares on technology and human activities.
