The two main indicators are Kp index and Solar X-Ray Flux. Kp index seems to be the key indicator of solar interference with our GPS units, normal "good" is under 3 and we start to worry when it's 5 or more as you can lose GPS lock because the weak satellite signals are being blocked/blasted with sun spot noise. If both numbers are showing high, GPS and compass can be affected I believe so I'd think twice about flying and perhaps not fly over scary places like water should the model lose GPS lock.
That's about all you need to know!
It's an IOS app called Solar Monitor |
