For those of you that consider this when you engage in GPS and RF activities, has anyone noticed the K-index yesterday and today? I mean, wow!!

I've been wondering exactly how much people have found the k index affecting their flights? I've never really noticed a difference in GPS performance on low/med/high k days... is the prevailing judgment to just "watch out" for gremlins in your GPS, or instead completely avoid GPS in any way until the sun calms down?

Yup I have an app that sends an alarm the minute the KP index goes into medium. Had an 8 out of 9 yesterday!
