This morning I checked UAV Forecast ready for a couple of flights over Crompton Moor and was a bit disappointed to see that it was saying the Kp was at five...I don't fly if the Kp is at five or above. Just to be sure I checked other sources for Kp values, three different web sites: one from Germany, one from Boulder Colorado, and one in the U.K. They were all showing a Kp of one or two.
I don't know where UAV Forecast gets it's data from but today it was clearly wrong...by a long shot. I decided to go with the value from the U.K. web site
Current geomagnetic activity in the UK and across the globe and ignore the Kp value from UAV Forecast.
It was also interesting to see that yesterday UAV Forecast was showing a Kp of one but the U.K. web site above showed it as SIX at the time I flew yesterday. I no longer trust UAV Forecast with regard to Kp index. If it was wrong yesterday and today, just how often have I been flying with a Kp at five or above?
