Latest advice, March 15 2012, from IPS, Sydney is that the weak ionosphere for the Antarctic region has resulted in increased absorption. The present proton event is declining. HF propagation conditions are expected to improve slightly over the next two days. Degraded ionospheric conditions possible after that affecting higher latitudes due to anticipated geomagnetic disturbances. The 10.7 cm Solar Flux is 141, and the equivalent daily smoothed sunspot number is 95. Solar activity is classified as high.
The following Spectrum Research summary was made on March 13, 2012, from a field site at the Canoe Launching Ramp Reserve, Lower Homestead Rd, Chirnside Park, 30 km east of central Melbourne, on the banks of the Yarra River.
Research period was 0400 to 0430, 3 pm to 3.30 pm here, with good propagation from all continents on 11 MHz and 13 MHz.
