NOAA forecasters say that G2-class geomagnetic storms are likely on Nov. 8th, 9th and 10th as additional CMEs hit/graze Earth’s magnetic field.
The source of the storm clouds is active sunspot 4274. High-latitude sky watchers should remain alert for auroras mixed with moonlight.

A CME passed close to Earth during the early hours of Nov. 6th, sparking a strong G3-class geomagnetic storm. This is just the beginning.
Three more CMEs (#1, #2, #3) are expected between now and Nov. 8th.
At least two should be direct hits.
This should keep the storm going (and maybe intensifying) for the rest of the week.

STRONG GEOMAGNETIC STORMS PREDICTED: Solar activity is suddenly high with multiple X-class and strong M-class solar flares since Monday. At least three CMEs are expected to graze or directly hit Earth this week, potentially sparking strong geomagnetic storms on Nov. 6-7.

A minor CME is heading for Earth, followed close behind by a high-speed stream of solar wind.
Their combined impact could cause G1/G2-class geomagnetc storms on Oct. 28/29.
High-latitude sky watchers should be alert for auroras.

ULTRA-FAST CME EXPLODES FROM THE FARSIDE OF THE SUN: Earth just dodged a bullet. An exceptionally fast CME erupted from the farside of the sun yesterday. It’s aimed at Venus, not Earth. Just last week, however, the instigating sunspot was directly facing our planet. Full story @ Spaceweather.com.

MULTIPLE CMEs ARE APPROACHING EARTH: As many as 3 CMEs are approaching Earth. According to a NOAA model, they could spark G2-class geomagnetic storms when they arrive on Oct. 16-17. High-latitude sky watchers (including observers in northern-tier US states) should be alert for auroras. Full story @ Spaceweather.com.

Minor G1-class geomagnetic storms are possible today as Earth moves through a stream of fast-moving solar wind.
The gaseous material is flowing from an equatorial hole in the sun’s atmosphere with gusts as high as 900 km/s (2 million mph).

An M1-class solar flare from sunspot 4236 hurled a CME into space on Oct. 3rd.
A NASA model predicts it will strike Earth on Oct. 8th.
Although it’s only a minor CME, it could spark a geomagnetic storm thanks to the Russell-McPherron effect, which links the magnetic fields of the sun and Earth around the equinoxes.

Earth has entered a stream of solar wind blowing faster than 700 km/s (1.6 million mph).
This is extending geomagnetic unrest for the third day in a row.
NOAA forecasters say G2-class geomagnetic storms are possible on Oct. 1st with continued auroras at high latitudes.

GIANT BUTTERFLY-SHAPED HOLE IN THE SUN’S ATMOSPHERE: A 500,000-km wide coronal hole has opened in the sun’s atmosphere, sending a stream of solar wind toward Earth. It could spark G1–G2 geomagnetic storms and auroras around Sept. 14th, enhanced by the Russell-McPherron effect. Full story @ Spaceweather.com.
