  • Current Northern Lights Status

    We want all 3 points in our numbered list below to be in a red font in order to assume there are good visible auroras occuring right now (in MN).
    Bz & Solar Wind update every minute. Kp updates every 5 minutes, forecasts every 15 minutes. Hit Refresh for updated data.

    Current Northern Lights Conditions:
    1. Kp: 4.67 [want 5+ in MN. See map]
    2. Bz: -5.0 nT [want < -3]
    3. Solar Wind: 669.1 km s-1 [want > 550]

    ** 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.
