Hello, I have a question about solar winds/flare. I read that it affects GPS so I'm trying to be careful, downloaded two apps to monitor with my android (Geomagnetic Storms and SAM) I understand that i should avoid flying (GPS Mode) if Kp-index is higher than 5. Geomagnetic Storm app gives me a graph of current Kp-index that updates every 3 hours, while SAM just states the condition. I want to know if its safe to fly when the graph shows Kp was high earlier on the day but its currently low? i.e. 3 or 6 hours before kp was 6 and now its around kp 3. Reason im asking is although geomagnetic storms app shows its currently low, SAM will just state "Storm" if it was high earlier that day. Attached are two screenshots taken the moment i wrote this topic. Thanks.
