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 [...]

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 [...]

May 2017: Ionospheric Propagation Predictions

Solar activity in May will be quite low with the possibility of class C flares, so geomagnetic activity is likely to reach G2 (moderate) storm levels. May HF propagation therefore will be poor on high bands with possible good DX openings on [...]

April 2017: Ionospheric Propagation Predictions

Solar activity is expected to be at very low levels and the geomagnetic field activity will be rather quiet, except for a few days due to some class C solar events. General propagation conditions will be fair for the rest of the forecast period.    

March 2017: Ionospheric Propagation Predictions

The solar activity in March should be at very low levels, with the possibility of Flare Class C during the month. Therefore are expected quiet Solar. Propagation in line with the low solar activity with interesting openings due to Equinox.

February 2017: Ionospheric Propagation Predictions

Solar activity is quite low, in line with the sunspots number decrease. The geomagnetic activity should be unstable due to sudden rises of the solar wind, which can cause temporary elevations of ionosphere ionization. In any case, the propagation [...]

November 2016: Ionospheric Propagation Predictions

Solar activity in October was low but characterized by different CME. The Earth’s magnetic field has responded with some storms, typical of the descending part of the Solar Cycle. The propagation of November will be quite in line with [...]

September 2016: Ionospheric Propagation Predictions

Solar activity is expected to be at low levels throughout September. The Solar Cycle is penetrating slowly in its minimum, so you can not expect special events except sporadic CME. So overall discrete propagation condition, good on low bands. 73 [...]

August 2016: Ionospheric Propagation Predictions

Solar activity continues to fall and several coronal emissions (CME) occur on the Sun, typical of the descending periods of the solar cycles. The activity has reached high levels and the geomagnetic field has reached minor storm levels. August [...]

July 2016: Ionospheric Propagation Predictions

Solar activity is expected to be very low throughout July. The geomagnetic field is expected fairly stable, so there will not be any surprise. The solar cycle confirms its slow descent, so the propagation will be quite low. 73 Fabio, iK0IXI www.ik0ixi.it “Semper [...]
