Maybe Alan can explain why we get these auroras and high K indexes at the sunspot minimum when the sun spot count and solar flux have been at rock bottom for weeks on end? Just checked, sunspot number still at 0, solar flux still at 67. A index (effectively yesterday's figure) for Kiel was 22 and K is currently 3 though has dropped from the earlier 5 figure. But why, and also why has there been an unusual sporadic E opening all weekend on 10m, which is most unusual in October. The guys playing in CQWW this weekend had a ball! I managed a QSO with C52C in the Gambia yesterday afternoon on 10m with my 5W. What is producing these effects. Doesn't seem to be anything to do with the sun as all is stonely quiet there and certainly nothing to produce huge auroras? Always thought solar weather was a black art (and in this case BLACK seems to be the key word!). By the way I gave both John GM4SLV and Ray GI3PDN calls last night but nil response so it looks like my qrpp ain't getting that far. Signals seemed nothing out of the usual, normal peaking 589 with deep QSB to noise level at times, I have certainly heard both John and Ray at better signals so not convinced aurora or not it was affecting 500kHz (certainly no auroral tones). Will very shortly be reconfiguring my vertical back to its Top Band configuration for the winter season so will be back in the spring if we still have NOVs. 73 Dave G3YMC http://www.davesergeant.com
