Propagation Summary
A C1 Solar Flare occurred on 10 Feb. Solar activity was at low levels on 12 Feb and very low levels on 13-18 Feb. However, data from the SOHO Observatory suggests that the Solar flare on Feb10 never arrived at earth until Feb 15, which apparently reduced the affect normally associated with such flares.
The Solar Flux was at background levels on 12-16 Feb and increased to moderate levels on 17
Feb followed by high levels on 18 Feb due to negative polarity effects from a coronal Hole Mass Ejection
Geomagnetic field activity ranged from quiet to active levels. Quiet conditions were observed on 12-14 Feb. On 15 Feb, arrival of the 12 Feb CME produced only one active period during the day.
Active levels were reached again on 17 and 18 Feb in response to influence from a negative polarity CH HSS. Solar wind speeds also increased on 18 Feb.
Forecast of Solar and Geomagnetic Activity up to 17 March 2018
Solar activity is expected to be very low through the outlook period.
The Solar Flux, having been at high levels up to 25 Feb, will decrease to normal levels until the end of the forecast period. Quiet to unsettled levels are expected on 04 March and 15 March, with quiet to active levels expected on 14 March and 16-17 March, as multiple, recurrent Coronal Hole High Speed Streamss are anticipated to become effective. The remainder of the outlook period is expected to observe quiet conditions. http://bit.ly/2jEdqR6
Long range solar forecasts by NASA suggest that solar Cycle 25, (peaking around the year 2022) will be the weakest solar cycle in centuries. https://go.nasa.gov/2F2afjK
