March 2018: Ionospheric Propagation Predictions

The average daily sunspots number has dropped in the last month, but the solar flux is expected to increase in the current month. So the March propagation will be better than the last few months. The equinox will be on March 20th, so there will [...]

February 2018: Ionospheric Propagation Predictions

The sunspots number is almost close to zero, so the propagation will be rather poor on the high bands, with short apertures during daytime. Conditions will be better on the lower bands with darkness.

January 2018: Ionospheric Propagation Predictions

Solar activity remained at very low levels throughout December 2017. No CME events direct to Earth were observed. Under the point of view of propagation, January 2018 will be a generally quiet period with the ever-decreasing Solar Cycle. The [...]

December 2017: Ionospheric Propagation Predictions

Solar activity is expected to be at very low levels during December, so HF propagation conditions will be poor on upper bands, while on lower bands we’ll see good DX condtions. December is the month of winter solstice, so more darkness [...]

November 2017: Ionospheric Propagation Predictions

Solar activity in October was at very low levels and no CME directed towards the Earth was observed. There are therefore no special events scheduled for November. HF propagation will generally be better on lower bands due to the increase in [...]

October 2017: Ionospheric Propagation Predictions

Last month (September) saw good openings thanks to the Equinox, which will last until mid-October. Solar activity is expected to be at low levels, no protonic event in sight, and therefore the general conditions in October will be quiet. Solar [...]

September 2017: Ionospheric Propagation Predictions

Solar activity in September will be at very low levels, so propagation will not be excellent, especially on the highest bands. The progressive rise of the dark hours will favor the lower bands. From mid-month onwards there will be the effects [...]

August 2017: Ionospheric Propagation Predictions

The solar activity for August will be quite low, with the Sun coming closer to its minimum. Openings on high bands will be more and more rare and we will have good conditions on low bands only from next fall.

July 2017: Ionospheric Propagation Predictions

July’s solar activity should be very low, with probability of class C flares. Slag propagation on higher bands, in line with the natural decay of solar cycle. Discrete conditions on low ranges with daytime Sporadic-E (Es) “blanketing” [...]

June 2017: Ionospheric Propagation Predictions

At the end of May there were 4 class B flares and on day 27th one of the Coronal Mass Emission (CME) hit the Earth, causing a sudden rise in the geomagnetic field. So the propagation has undergone a rather marked degradation. June’s solar [...]
