    ** The Wing Kp Geomag Activity Index updates every 15 minutes with a short term forecast which is useful for determining what the Aurora Borealis (Northern Lights) activity may be like over the next hour or so. It is also useful to anticipate a short term trend in activity from whatever it is currently at. This data is prepared by the U.S. Dept. of Commerce, NOAA & Space Weather Prediction Center. However, I did take the liberty to skew the forecast numbers by initializing off the latest observation when the observation and first forecast a few minutes away don't match up. So only the forecasted trend is utilized and applied to the latest observation. This method seems more accurate.
