NOAA forecasters say that minor G1-class geomagnetic storms are possible on Oct. 13th when a solar wind stream is expected hit Earth’s magnetic field. There’s a chance the storm could escalate to category G2 if an off-target CME also grazes Earth. It was launched by a solar tsunami on Oct. 10th.

Earth’s magnetic field is about to get hit by as many as three CMEs–the first on Oct. 9th, the second and third on Oct. 11th.
The series of impacts could spark category G1 (Minor) to G3 (Strong) geomagnetic storms with perfect timing for aurora photographers.

A CME IS COMING, AURORAS LIKELY: New sunspot 4549 erupted this morning, hurling a full-halo CME straight toward Earth. Forecast models predict it will arrive on Oct. 9th, possibly sparking a G2-class geomagnetic storm. The timing is perfect for aurora photographers as a nearly new Moon keeps rural skies dark.

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.
