3-Day Forecast for Inuvik, Northwest Territories

Tonight's forecast peaks at Kp 3.7, and Inuvik needs about Kp 1 for the aurora to clear the northern horizon - so this is a promising night. It may even appear high overhead rather than just low on the northern horizon.

Aug 30

Quiet

Low chance of aurora - geomagnetic activity is expected to stay quiet.

Best time to look up: 12:00 AM–3:00 AM MDT

10% chance of elevated activity · Kp 1.67 during viewing window

Interplanetary Magnetic Field Bz-5.7 nT now

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

Total IMF Field Bt9 nT now

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.

Storm Trend37 now

Prediction score (0-100) over the last 24 hours, logged every 5 minutes. 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-34 nT now

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

Speed: 401 km/s now Pressure: 2.7 nPa now

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.

24-hour trend charts for the values above, so you can see whether conditions are building or fading.
