What kind of numbers, from Space Weather predictions, would you not rely upon your GNSS observations? In other words, not employ your GPS tools.
Thank you in advance!

For what it's worth, NOAA Manual NOS NGS 9, "User Guidelines for Single Base Real Time GNSS Positioning," from 2014, says "Recommendations: Do not try to perform RT during level G3 - G5 storm events." I've not found a more recent guideline, nor one for network RTK nor for static observations. This recent geomagnetic storm has reached as high as G4.
