3-Day Forecast for York, England, United Kingdom

Oct 13
Global: Active York: Borderline

Kp 4 is right around the roughly Kp 4 York needs - a borderline night, worth a look to the north.

Global: NOAA has issued a watch for this night (see below) - moderate planetary activity, aurora across the high-latitude zone.

CME Watch: G1 (Minor) · Kp 5 expected

Best time to look up: 04:00–07:00 BST

35% chance of elevated activity · Kp 4 during viewing window, up to Kp 5 depending on CME timing

Oct 14
Global: Active York: Not expected

Kp 3.3 is short of the roughly Kp 4 the aurora needs to clear the northern horizon from York.

Global: Moderate planetary activity expected - aurora across the high-latitude zone, and lower with a good substorm.

Best time to look up: 19:00–22:00 BST

35% chance of elevated activity · Kp 3.33 during viewing window

Oct 15
Global: Quiet York: Not expected

Kp 2.3 is short of the roughly Kp 4 the aurora needs to clear the northern horizon from York.

Global: Quiet planetary conditions expected - aurora mostly confined to the far north.

Best time to look up: 22:00–01:00 BST

20% chance of elevated activity · Kp 2.33 during viewing window

Interplanetary Magnetic Field Bz8.2 nT now

17 0 -12 Oct 12, 1 PM Oct 12, 7 PM Oct 13, 1 AM Oct 13, 7 AM Oct 13, 1 PM

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

Total IMF Field Bt9 nT now

18 0 Oct 12, 1 PM Oct 12, 7 PM Oct 13, 1 AM Oct 13, 7 AM Oct 13, 1 PM

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 Trend15 global now

100 50 0 Oct 12, 1 PM Oct 12, 7 PM Oct 13, 1 AM Oct 13, 7 AM Oct 13, 1 PM

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, 1 PM Oct 12, 7 PM Oct 13, 1 AM Oct 13, 7 AM Oct 13, 1 PM

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.

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.
