Power systems: Weak power grid fluctuations can occur.

Spacecraft operations: Minor impact on satellite operations possible.

Other systems: Migratory animals are affected at this and higher levels; aurora is commonly visible at high latitudes (northern Michigan and Maine).
Enhanced protection from UV radiation from the Sun is required. A UV index reading of 8 to 10 means very high risk of harm from unprotected sun exposure. Take extra precautions because unprotected skin and eyes will be damaged and can burn quickly. Minimize sun exposure between 10 a.m. and 4 p.m. If outdoors, seek shade and wear sun protective clothing, a wide-brimmed hat, and UV-blocking sunglasses. Generously apply broad spectrum SPF 30+ sunscreen every 2 hours, even on cloudy days, and after swimming or sweating. Bright surfaces, such as sand, water, and snow, will increase UV exposure.
On land:
There is a light continuous stream of wind that is felt by the face; leaves rustle; ordinary vanes moved by wind.
At Sea:
Weak and short waves in the sea, still short, but more pronounced. Crests have a glassy appearance and do not break.
Protection from UV radiation from the Sun is necessary. A UV index reading of 6 to 7 means high risk of harm from unprotected sun exposure. Protection against skin and eye damage is needed. Reduce time in the sun between 10 a.m. and 4 p.m. If outdoors, seek shade and wear sun protective clothing, a wide-brimmed hat, and UV-blocking sunglasses. Generously apply broad spectrum SPF 30+ sunscreen every 2 hours, even on cloudy days, and after swimming or sweating. Bright surfaces, such as sand, water, and snow, will increase UV exposure.
On land:
The thin branches and leaves on the trees fluctuate continuously; wind extends light flag.
At Sea:
Light and short waves are clearly visible at sea. Foam of glassy appearance. Perhaps scattered white horses.
On land:
The wind picks up dust and small pieces of paper; small branches are moved.
At Sea:
The sea is moderately rough. Waves appear in the form of elongated ridges, some of which are overturned; fairly frequent white horses.
Protection from UV radiation from the Sun is not necessary. A UV index reading of 0 to 2 means low danger from the sun's UV rays for the average person. Wear sunglasses on bright days. If you burn easily, cover up and use broad spectrum SPF 30+ sunscreen. Bright surfaces, such as sand, water, and snow, will increase UV exposure.
On land:
Thin branches and tree trunks sway, and the wind is felt by the hand.
At Sea:
The sea is rough, not very large waves are well developed in length; many white horses are formed.
