## What NOAA SWPC has issued for 9 October 2026

According to NOAA SWPC, a G2 geomagnetic storm watch is active. It was issued on 6 October at 16:33 UTC and predicts a storm at G2 level. The full list of alerts, watches and warnings is published on the [NOAA SWPC alerts page](https://www.swpc.noaa.gov/products/alerts-watches-and-warnings).

## How high does the Kp go in the next three days?

Per the [NOAA SWPC 3-day forecast](https://www.swpc.noaa.gov/products/3-day-forecast), the largest Kp per day is:

- Friday, 9 October 2026: Kp 6, peak slot 18-21 UTC, G2
- Saturday, 10 October 2026: Kp 4, peak slot 00-03 UTC, below G1
- Sunday, 11 October 2026: Kp 5, peak slot 03-06 UTC, G1

The largest Kp in the whole forecast is 6. The strongest window is therefore the evening of 9 October in UTC terms.

## Which destinations have enough forecast Kp?

Every destination on the list has a forecast Kp at or above the Kp it needs. The list runs from Ilulissat, Greenland and Longyearbyen, Svalbard at Kp 1 needed, through Whitehorse, Yukon, Canada and Rovaniemi, Finnish Lapland at Kp 2, Anchorage, Alaska and Lerwick, Shetland, Scotland at Kp 3, Edinburgh, Scotland at Kp 4, to Kiel, northern Germany at Kp 6. A full set of places is on the [northern lights locations page](/locations/).

## What else has to line up for the northern lights?

A forecast Kp at or above the local threshold is one part of the picture. NOAA notes on its [tips for viewing aurora](https://www.swpc.noaa.gov/content/tips-viewing-aurora) that a dark sky and clear weather matter too. It remains open whether cloud cover will cooperate at any given place. The 27-day outlook gives a daily largest Kp only, not a promise for a specific night.
