NOAA’s Space Weather Prediction Center (SWPC) says solar activity is “high and intensifying,” and radio blackouts reaching the R3 levels have been observed over the past 24 hours. An R3 event can cause a wide-area blackout of HF radio communication and a loss of radio contact for about an hour on Earth’s sunlit side. Low-frequency navigation signals may be degraded for about an hour as well. A…

NASA is now accepting proposals from US schools, museums, science centers and community youth organizations to host an Amateur Radio on the International Space Station (ARISS) contact between November 1, 2012 and May 1, 2013. To maximize these radio contact opportunities, NASA is looking for organizations that will draw large numbers of participants and integrate the contact into a well-develop…
