Equipment
What to bring for a successful aurora watch in the UK, from what to wear to the apps you actually need.
Staying warm
The UK is cold, dark and damp at night, even in summer at altitude. Standing still for an hour in Scottish winter temperatures is brutal. Warmth is not optional.
Base layer
Merino wool or synthetic moisture-wicking. Never cotton, because it traps cold and sweat. A thin base layer under everything else makes a huge difference.
Mid layer
Fleece or down jacket. Down is warmer for the weight; fleece works better when damp. Wear both if it's genuinely cold.
Outer shell
Waterproof, windproof jacket and trousers. Coastal and highland sites get wind and drizzle even on otherwise clear nights.
Gloves
Bring two pairs: thin liner gloves for operating phone/camera, and thick outer mitts for when you're not actively shooting. Cold hands end aurora watches quickly.
Hat and neck gaiter
A significant amount of body heat escapes from the head and neck. Both should be in your bag even if conditions seem mild.
Footwear
Waterproof boots with warm socks. Standing on wet grass for two hours in trainers is genuinely miserable. Thick walking socks or thermal socks under waterproof boots.
Hand and foot warmers
Chemical hand warmers (HotHands or similar) are cheap and effective. Tuck one in each glove and one in each boot for cold nights.
Sitting mat or chair
A foam sit mat weighs almost nothing and keeps your legs off cold wet ground. A small camping chair is worthwhile for longer watches.
Lighting
White light destroys your dark adaptation, and it takes 20 to 30 minutes to recover full night vision after even a brief torch flash. Use red light only once you're set up.
Red-light head torch
A head torch with a red LED mode is essential. Red light preserves dark adaptation. Keep a hand free by using a head torch rather than holding one.
Spare batteries
Cold drains batteries faster than you expect. Carry spares in an inside pocket, since warm batteries last far longer than cold ones.
Phone screen brightness
Dim your phone screen completely before you go out. Enable night mode / red filter. Aurora-watching apps should have a dark mode, so use it.
Apps
You only need a handful of apps. More is not better. Pick one or two and know them well.
Auroracast
Live Hp30, solar wind, Bz, cloud cover and UK-specific forecasts. Enable push alerts for when Hp30 rises above your threshold. Use Sky Tonight for moon phase, planets, dark sky window, ISS passes, meteor showers, Milky Way and NLC planning.
Clear Outside
The best cloud cover and astronomical seeing forecast for UK locations. Check this alongside the Auroracast forecast before heading out.
SpaceWeatherLive
Detailed real-time data from Solar1, ACE and other space weather satellites. Good for monitoring Bz during an active event. Information-dense, so use it once you know the basics.
PhotoPills / PlanIt
For photographers: plan your composition using the sky map and visualise where the moon will rise. For Milky Way timing, Auroracast's Sky Tonight page now includes galactic centre rise, transit, and set times for your location.
What3words
Share your exact location in remote areas for safety. UK mountain rescue services use it, so if you're going somewhere rural and isolated, worth having.
In the field
Binoculars
A good pair of binoculars (10x50 or 8x42) reveals structure in the aurora, such as curtains, rays and colour gradients invisible to the naked eye. Also great for star clusters.
Thermos flask
Hot drink. Non-negotiable on winter watches. Morale is equipment.
Snacks
High-energy snacks (nuts, chocolate, flapjack) keep your core temperature up. Cold burns calories faster. Eating regularly while outside in the cold makes a real difference.
Portable power bank
Cold drains phone batteries rapidly. A 10,000 mAh power bank will keep your phone alive through a long watch and also charge a camera battery if needed.
First aid kit
A basic kit in your bag for remote sites. For highland Scotland especially, a foil emergency blanket and whistle are worth adding.
Offline maps
Download maps of your intended area before leaving. Mobile signal is non-existent at most good dark-sky locations. OS Maps or AllTrails work offline.
The honest truth
The single biggest piece of equipment for aurora watching is patience. You can spend a fortune on camera gear and still miss the display because you went home an hour early. Check the forecast, get under dark skies, stay warm, and wait. The aurora comes to those who are actually outside.
