A new NOAA forecast model predicts that two CMEs will sideswipe Earth on Sept. 8th. The one-two punch could spark a G2-class geomagnetic storm with high latitude auroras.

A CME expected to hit Earth on Aug 28th is overdue.
But NOAA forecasters think it might still arrive on Aug. 29th.
An impact today could spark G1/G2 geomagnetic storming with high-latitude auroras.

LUNAR ECLIPSE AND CME IMPACT: There’s a lunar eclipse this week, and, in a rare coincidence, a CME might hit Earth while the Moon is in shadow. This sets the stage for a potential aurora-Moon photo-op. The eclipse will be visible from Coast to Coast in the USA. Full story and timetables @ Spaceweather.com.

Sunspot 4513 has developed a ‘beta-gamma-delta’ magnetic field thatharbors energy for X-class solar flares.
Unlike Thursday’s M8-class flare, which missed Earth, future flares will not miss.
The sunspot has us in the strike zone now.

A BIG CME JUST LEFT THE SUN: NASA and NOAA models agree that it should graze Earth on Aug. 2nd.
A glancing blow would spark geomagnetic storms and high-latitude auroras this weekend.

The sun has produced a number of minor CMEs this week. Emphasis on minor. Nevertheless, almost all of them have an Earth-directed component. A series of glancing blows on July 31st and Aug. 1st could produce a G1-class geomagnetic storm with high-latitude auroras.

4TH OF JULY AURORA WATCH: Multiple CMEs are heading for Earth, prompting an aurora watch for the 4th of July holiday weekend. The CMEs were launched by a series of strong solar flares this week, including one X-class eruption. If they all hit, they could spark moderate to strong geomagnetic storms in the nights ahead.

EARTH-DIRECTED X-FLARE AND CME: Solar activity is at high levels following multiple explosions in new sunspot AR4479. The strongest so far, an X1.1-class solar flare on June 30th, hurled a CME directly toward Earth. This will bring a chance of geomagnetic storms and auroras later this week. Full story @ Spaceweather.com.

Another large sunspot is growing in the sun’s northern hemisphere. AR4479 is directly facing Earth and it has a delta-class magnetic field that poses a threat for X-class solar flares.

BIG SUNSPOT ALERT: A remarkably large sunspot is emerging over the sun’s southeastern limb. Not only does it pose a potential threat for Earth-directed flares, but also it is big enough for easy observing by amateur astronomers. Find out how to see it on today’s edition of Spaceweather.com.
