Propagation News – 21 April 2019

Last week was a little better propagation-wise. The Australian IPS T index, as used by the ASAPS computer program for predicting HF propagation frequencies, turn positive again after a week of being at zero or even negative. The T index can be best regarded as an “equivalent sunspot number” – the sunspot number which would best match the observations made …

Propagation News – 14 April 2019

This has been a difficult time for HF. The solar wind has remained active and the Bz component exhibited several periods of prolonged southward deflection, meaning it more easily coupled with the Earth’s magnetic field. Solar wind speed ranged mostly from 425-475 km per second and this was enough to keep the Kp index elevated, often to four. The net …
