Lads my k-index app has reached 4 for the first time in a few months so be careful and keep an extra eye on your satellite coverage just in case it goes above 5. Solar flares must be about.
 
Maybe nothing to worry about, it could jump back to level 1 in a few mins but just a friendly warning to any flyers dont know aboit this. When the k-index goes above 5 it means the likes of solar flare activity is high and can disrupt gps signals meaning your bird could lose sight of a sat or 2 and go into atti mode withoit you realising. There are apps for android and ios. Just search for them. Mine is so simple it doesnt even have an Interface it just updates the k-index number in the corner of my phone the whole time and refreshes every 30 mins
 
Here's a good source of the K-index estimate from NOAA.
