Power systems: Possible widespread voltage control problems and
some protective systems will mistakenly trip out key assets from the grid.
Spacecraft operations: May experience surface charging and tracking problems,
corrections may be needed for orientation problems.
Other systems: Induced pipeline currents affect preventive measures, HF radio propagation sporadic,
satellite navigation degraded for hours, low-frequency radio navigation disrupted,
and aurora has been seen as low as Alabama and northern California (typically 45° geomagnetic latitude.).
Solar ultraviolet index:7,9 (High)
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.
