    STRONG SOLAR FLARE AND CME: After days of suspenseful quiet, huge sunspot AR2665 finally erupted on July 14th (0209 UT), producing a powerful M2-class solar flare. The explosion was underway for more than two hours and hurled a bright coronal mass ejection (CME) toward Earth. Geomagnetic storms and high-latitude auroras are likely when the CME arrives this weekend. Visit Spaceweather.com for images and updates.

    Aurora prediction is often an embarrassing failure, but here is the prediction for tonight.

    July 17 05:00 UT Levels back to normal. Few people saw anything. Waste of energy, having aurora in the daytime.😃

    22:00 I hope someone in Scandinavia and Britain gets to see aurora. Otherwise, good luck to USA / Canada in several hours.

    16:00 UT Strong Aurora all around the Arctic circle. Unfortunately, it is daylight in most areas, but can be seen from lower latitudes looking towards north. Aurora affected by sunlight, which changes appearance. May be seen from Western Russia. Low in sky from Tasmania and S New Zealand. Best in Antarctica. Soon will be visible in northern Europe in places that have darkness at this time of year, as long as it doesn't fade.

    12:00 UT Aurora in north west US and New Zealand.

    09:00 UT Aurora now in Northern Canada and Alaska, in those areas where it is dark.
