Alerts

AuroraWatch UK alerts: link: https://aurorawatch.lancs.ac.uk/alerts/

Following @aurorawatchuk on Twitter is the easiest way to receive alerts. Twitter accounts are free and you may be able to have Twitter send our tweets (messages) directly to your mobile phone as SMS messages. You can also limit the times of day when tweets should go to your mobile phone. We’ll automatically tweet for red and amber alerts, and also for minor geomagnetic activity.
Smartphone apps are available for Android and iOS (iPhone, iPad). They use the same data as the other alert methods but may behave slightly differently.

Tips on viewing

Tips on viewing the Aurora - https://www.swpc.noaa.gov/content/tips-viewing-aurora - "Being able to see the Aurora depends mainly on two factors, geomagnetic activity (the degree of disturbance of the earth's magnetic field at the time) and your geographic location. Further considerations are the weather at your location, and light pollution from city lights, full moon and so forth."

How far South can the aurora be observed - https://www.swpc.noaa.gov/sites/default/files/images/u2/Aurora_Kp_MapEurAsia.png - you need to know:

G for the NOAA Geomagnetic Storm Index (0-5)
or
Kp for the Planetary K index (0-9)
South of England needs G=5, Kp=9. Isle of Man needs G=3, Kp=7.

When to view

From here: https://www.discover-the-world.com/northern-lights/ ...

Spring and autumn generally provide more stable weather conditions and milder temperatures plus there is greater aurora activity around the equinoxes.
November through to February offer the darkest skies and longer evenings for maximum sky-gazing.
The strongest lights tend to appear between 9pm and 2am, though the best sightings often occur between 11pm and midnight.
Between 6 p.m. and 1 a.m. is the most intense period of the day. The highest probability within this is between 10 and 11 p.m. However, this is a guideline, and during the Polar night aurorae can be observed as early as 4PM, and all through the night. The most intense displays last some 5–15 minutes each. In periods of strong activity, one can generally expect flares starting in the early evening, peaking around 10pm, and going on into the early morning hours.
