The Moon:  Moonrise 03:50, Moonset 18:03, Moon phase: waning crescent waning crescent
 Geomagnetic Field: Active
  Water temperature: +9 °C
 Ultraviolet index: 3,9 (Moderate)
A UV index reading of 3 to 5 means moderate risk of harm from unprotected sun exposure. Stay in shade near midday when the sun is strongest. If outdoors, 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.

The Moon:  Moonrise 06:32, Moonset 23:16, Moon phase: waxing crescent waxing crescent
 Geomagnetic Field: Moderate Storm

Other systems: HF radio propagation can fade at higher latitudes, and aurora has been seen as low as New York and Idaho (typically 55° geomagnetic latitude.).
  Water temperature: +10 °C
 Ultraviolet index: 0,9 (Low)
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.
