Two CMEs are heading for Earth. The plasma clouds were expelled from the sun on August 20-21 by a pair of erupting magnetic filaments. NOAA forecasters expect the CMEs to arrive on August 23-24, possibly sparking geomagnetic storms around the poles.
ANOTHER CME IS ON THE WAY: As Earth passes through the wake of one CME, which did little to stir geomagnetic activity on Aug. 20th, another CME is on the way. NOAA forecasters expect a coronal mass ejection hurled into space yesterday by an erupting magnetic filament to deliver a glancing blow to Earth's magnetic field on Aug. 23rd -- 24th. High-latitude sky watchers should be alert for auroras.
ANOTHER SUNDIVING COMET: Here we go again. Another comet is diving into the sun, the second one this week. Coronagraphs onboard the Solar and Heliospheric Observatory (SOHO) are monitoring the death plunge:
The icy comet, which probably measures a few 10s of meters wide, is vaporizing furiously and is not expected to survive much longer.
Like the comet that came before it, this one is a member of the Kreutz family. Kreutz sungrazers are fragments from the breakup of a single giant comet many centuries ago. They get their name from 19th century German astronomer Heinrich Kreutz, who studied them in detail.
Because of their common parentage, sungrazers often come in clusters. After today's sungrazer evaporates, it wouldn't be surprising to find yet another in the offing. Stay tuned.

This weekend the 10th & 11th of August wasn't a moderate geomagnetic storm as we had expected (see previous post Geomagnetic Storm Watch 2013 08 10 11 HD Geomagnetic Storm Watch 2013 08 10 11 HD )  maybe because the CME had missed earth altogether or it hasn't arrived yet.
But we did get a moderate solar flare C8.4 at 21:58 UTC Sunday evening and a more intense flare class M1.5 around Sunspot 1817 in the southern hemisphere. These two solar flares are geoeffective. The M1.5 class created a wave of ionization in the upper atmosphere above Europe and might have hurled a coronal mass ejection toward Earth.
More M class flares and CMEs can be expected from the growing sunspot 1817.
Also more solar wind to inundate the earth's magnetosphere on August 16-17th is from a new gigantic coronal hole.
Thank you for watching and hope to see you again soon :)

Filament Eruption and CME
An eruptive filament generated a partial halo coronal mass ejection on Wednesday evening. The latest analysis by the Goddard Space Flight Center is calling for an impact to our geomagnetic field by early on August 11th. The latest NOAA Space Weather Prediction Center update is calling for an indirect impact by late on August 10th. This latest plasma cloud is in addition to an earlier CME that was also somewhat directed towards Earth. Minor geomagnetic storming will be possible this weekend should the plasma clouds sweep past Earth.
Geomagnetic Storm Watch
An elevated solar wind stream flowing from a narrow Coronal Hole (CH) is currently streaming past Earth. This in itself is not expected to stir up much in the way of geomagnetic activity, but should the first of two possible CMEs deliver an expected glancing blow within the next 24 hours, minor G1 geomagnetic storming at high latitudes could unfold due to the combined effects. A second CME could deliver another glancing blow by August 11th. Both were the result of filament eruptions.
WATCH: Geomagnetic Storm Category G1 Predicted
Highest Storm Level Predicted by Day:
Aug 09: None (Below G1) Aug 10: G1 (Minor) Aug 11: G1 (Minor)
Potential Impacts: Area of impact primarily poleward of 60
degrees
Geomagnetic Latitude.
Induced Currents - Weak power grid fluctuations can occur.
Spacecraft - Minor impact on satellite operations possible.
Aurora - Aurora may be visible at high latitudes, i.e., northern tier of the U.S. such as northern Michigan and Maine.

The most powerful flare to date - Solar Maximum does not disappoint.

Update from yesterdays class X1.7 and class X2.8 coronal ejection.
All other visible sunspot regions appear to be stable at this time. There will remain a chance for moderate M-Class solar flares and perhaps another isolated X-Class event within the next 24-48 hours, particularly around Sunspot 11748.

A sunspot on the sun's eastern limb is crackling with powerful X-class solar flares. It announced itself with an X1.7-class eruption on May 13th at 0217 UT, quickly followed by an X2.8-class flare at 1609 UT. These are the strongest flares of 2013, and they signal a significant uptick in solar activity. More eruptions are in the offing.
 ALERT: Type II Radio Emission
Begin Time: 2013 May 13 1557 UTC
Estimated Velocity: 949 km/s
Description: Type II emissions occur in association with eruptions on the sun and typically indicate a coronal mass ejection is associated with a flare event.
 
ALERT: Type IV Radio Emission
Begin Time: 2013 May 13 1557 UTC
Description: Type IV emissions occur in association with major eruptions on the sun and are typically associated with strong coronal mass ejections and solar radiation storms.
 
SUMMARY: 10cm Radio Burst
Begin Time: 2013 May 13 1553 UTC
Maximum Time: 2013 May 13 1601 UTC
End Time: 2013 May 13 1618 UTC
Duration: 25 minutes
Peak Flux: 520 sfu
Description: A 10cm radio burst indicates that the electromagnetic burst associated with a solar flare at the 10cm wavelength was double or greater than the initial 10cm radio background. This can be indicative of significant radio noise in association with a solar flare. This noise is generally short-lived but can cause interference for sensitive receivers including radar, GPS, and satellite communications.

Solar activity is now at moderate levels thanks to an isolated M1.1 Solar Flare around Sunspot 1731 in the northern hemisphere. A Coronal Mass Ejection (CME) is visible in the latest STEREO Ahead COR2 imagery. It appears that a majority of the plasma cloud was directed north of the Sun-Earth field.
Auroras this weekend.

A moderate solar flare reaching M1.0 was observed around Sunspot 1726 at 10:29 UTC this morning. The blast itself was impulsive in nature and a large Coronal Mass Ejection is not expected. This region maintains a fairly impressive magnetic structure, especially within the trailing spot cluster and has the potential for an even stronger event.
