What I have done is to analyse the geomagnetic activity over the last 10 years and plot out the number of sequenctial "quite" days where the Kp Index was less than 5. The period early in January suggested that this might lead to good conditions for paths of over 3000kms. The plots show that there are more long quiet spells as we drop down the solar cycle to the minimum, but there is still that amount of activity to give the conditions a kick in our favour. As the financial watchdogs say "past performance is no guarantee of future results", but it is a lot better than nothing. At the present I feel like an early weather forecasters when if you said "the weather tomorrow will be the same as today", you would be right about 52 % of the time....which is quite good going, but slightly dumb forecasting!! If you want to look at my ideas and plots they are now on my web site, go direct to the forecast page with http://www.alan.melia.btinternet.co.uk/forecast.htm Any thoughts, data, conflicting references etc, gratefully received. I hope it provides an incentive to keep working towards longer paths, and helps maybe understand how to pick the times to try for them. Cheers de Alan G3NYK alan.melia@btinternet.com
