    Chance of seeing it (aurora × clear sky × dark)CloudDaylight

    Looking ahead

    Storm level comes from NOAA's 3-day Kp forecast; chance and cloud are for that hour at your location.

    Solar wind at the spacecraft (L1)

    Bz
    –
    South tilting Bz helps aurora!
    Bt
    –
    Bt = total strength of the magnetic field in the solar wind (nT). Stronger fields can drive stronger storms.
    Speed
    –
    km/s
    Density
    –
    Density = particles per cm³ in the solar wind. Higher density means a harder push on Earth's field.

    Kp storm level
    Dashed line = Kp 5, where storms (G1) begin.
    Bz (solar wind magnetic tilt, nT)
    Red area = southward Bz, which helps aurora. The orange line is when the newest reading reaches Earth; nothing is predicted past it.

    NOAA map of the northern hemisphere showing where aurora is likely right now

    NOAA's live aurora forecast map. The brighter the green to red glow, the higher the chance of aurora there. Ireland is on the western edge of Europe.

    Infrared satellite picture of cloud over Ireland, the UK and western Europe right now

    Live infrared satellite picture from EUMETSAT. White and light grey are cloud (the brighter, the higher and thicker); dark is clear sky or sea. It works at night too.
