Interpreting the data

Reading https://www.qrparci.org/resource/FDIM81.pdf to gain a bit more knowledge.

• K index
  • 0-9 published every 3 hours with a 24 window
  • Magnetometers on the earth measure the condition of our magnetic field. The amount of movement (or, “wiggling”) is averaged and reported by NOAA
• A index
  • 0-20 is a good number
  • 0-400 representing the overall planetary geomagnetic conditions for the UTC day
