NOAA Geomagnetic Activity Observation and Forecast The greatest observed 3 hr Kp over the past 24 hours was 1 (below NOAA Scale levels). The greatest expected 3 hr Kp for Sep 27-Sep 29 2013 is 3 (below NOAA Scale levels).

Today I was flying Arducopter V3.0.1 around in Stabilize for about 8 minutes and then switched into Loiter. It had good GPS (10 satellites) and good HDOP (1.60). It was perfectly solid and holding very still in loiter, but then all of a sudden it rolled way to the right and took off like a rocket. I immediately switched into Stabilize to regain control.
Looking at the logs, I expected to see loss of GPS satellites and larger HDOP at the point Loiter went crazy, but in fact I saw the opposite: Num satellites actually went up, from 10 to 11, and HDOP went down, from 1.60 to 1.57 at that point.
This issue could be very dangerous, because some people like to use loiter to land, and if it flies off so suddenly at low altitude when you're least expecting it because of how rock solid the loiter is at first, then it could easily hit and injure someone.Flash log attached. Graph of log zoomed to the point the issue occurred:
