Kp is a 0–9 measure of geomagnetic activity in 3-hour blocks; G1–G5 are NOAA's storm levels (Kp 5–9). Forecast from the NOAA Space Weather Prediction Center, updated several times a day.

27-day outlook

NOAA's 27-day outlook doesn't expect Kp 6 or more on any day through Sat, Nov 21.

Fri, Oct 30Sat, Nov 21

The outlook is based on the Sun's 27-day rotation: active regions and coronal holes that faced Earth last rotation are expected back. It is a rough guide, and big storms usually come with only 1–3 days' warning.

NOAA's OVATION model estimates the chance of seeing aurora overhead at each point for the next 30–90 minutes. Aurora seen low on the horizon can come from up to about 1,000 km closer to the pole, so we also show the highest chance in that direction.

How to see the aurora from Vilnius

“Kp needed” uses NOAA's rule of thumb in corrected geomagnetic latitude (AACGM-v2 model, epoch 2026). It is approximate: the oval's shape changes from storm to storm.
