Interplanetary Magnetic Field Bz8.4 nT now

14 0 -12 Oct 12, 10 AM Oct 12, 4 PM Oct 12, 10 PM Oct 13, 4 AM Oct 13, 10 AM

Southward (negative) Bz favors aurora. Observed data only, no forecast product exists for Bz.

Total IMF Field Bt8.7 nT now

18 0 Oct 12, 10 AM Oct 12, 4 PM Oct 12, 10 PM Oct 13, 4 AM Oct 13, 10 AM

Total interplanetary magnetic field strength - the ceiling on how negative Bz can go. A rising Bt alongside a still-fluctuating Bz often leads a stronger southward turn. Observed data only, no forecast product exists for Bt.

Global Storm Trend18 global now

100 50 0 Oct 12, 10 AM Oct 12, 4 PM Oct 12, 10 PM Oct 13, 4 AM Oct 13, 10 AM

Global (hemisphere-wide, not this city) prediction score over the last 24 hours, logged every 5 minutes - may differ from the Prediction ring above, which is specific to this location and time of night. Red above 70, yellow 50-70, teal below 50 - same thresholds used everywhere else on this page. Dashed line is the overall trend.

Dst History-9 nT now

27 0 -57 Oct 12, 10 AM Oct 12, 4 PM Oct 12, 10 PM Oct 13, 4 AM Oct 13, 10 AM

Kyoto Dst geomagnetic storm index over the last 24 hours. Negative = ring-current energy stored = an active storm, not just predicted. Red below −50nT, yellow −20 to −50nT, teal above −20nT.

Solar Wind Speed & Pressure

Each line is scaled independently to its own 24h range (different units) - watch the shape, not a shared axis. A rising speed line or a pressure spike can signal an incoming stream or shock before Bz/Dst move.

Nerd Mode: See what’s really driving the score. Live solar wind, Bz, Kp, Dst, CME timing, and more. Data comes from NOAA SWPC and the Kyoto WDC, with a few metrics calculated here from the raw data. Live data refreshes every minute; trend charts every five.
