INCOMING CME: [/FONT]Magnetic fields above sunspot 1261 erupted this morning at 0648 UT, producing an M1-class solar flare. The blast also hurled a bright coronal mass ejection toward Earth. This movie from the STEREO-Ahead spacecraft shows the cloud racing away from the sun at almost 900 km/s. Geomagnetic storms are possible when the CME reaches Earth on or about August 5th. Stay tuned for updates.

จับตาระเบิดลูกนี้ Class M6

[FONT=Arial, Helvetica, sans-serif]M6-CLASS SOLAR FLARE: [/FONT]Earth orbiting satellites have just detected a significant M6-class solar flare. The source appears to be sunspot 1261. Increased energetic proton fluxes are possible in the vicinity of Earth. Stay tuned for updates.

SpaceWeather.com -- News and information about meteor showers, solar flares, auroras, and near-Earth asteroids

 

[FONT=Arial, Helvetica, sans-serif]M6-CLASS SOLAR FLARE: [/FONT]Sunspot 1261 unleashed another strong solar flare this morning--an M6-class flash at 1348 UT. Like yesterday's eruption from the same active region, this explosion propelled a CME in the general direction of Earth. ETA: August 5th. Stay tuned for additional analysis.
UPDATE: A listening station above the Arctic Circle in Norway reports ionospheric waves and VHF radio noise associated with today's M6-flare: their data.


[FONT=Arial, Helvetica, sans-serif]INCOMING CLOUD: [/FONT]Yesterday's M1-class eruption from sunspot 1261 was observed by three spacecraft: SOHO, STEREO-A and STEREO-B. Using data from those three points of view, analysts at the GSFC Space Weather Lab have made a 3-dimensional model of the CME now en route to Earth. Click on the image to launch a computer-generated movie of the expanding cloud:

​

According to their work, the CME left the sun traveling 900 km/s and should reach Earth (denoted by a yellow dot in the simulation) on August 5th at 0300 UT plus or minus 7 hours. Another cloud produced by today's M-flare may be right behind it; stay tuned for movies of that one, too. Mild to moderate geomagnetic storms are possible when these CMEs arrive on August 5th and 6th. Aurora alerts: text, voice.

Strong solar activity – M9.3 solar flare took place, expecting CMEs

Sunspot 1261 is at it again, this time producing a strong M9.3 Solar Flare at 03:57 UTC Thursday morning. It also turns out that yet another Coronal Mass Ejection (CME) was produced and you can see it in the still image below captured by STEREO Ahead.


Proton Levels are on the increase. (SolarHam)














Yesterday’s M1-class eruption from sunspot 1261 was observed by three spacecraft: SOHO, STEREO-A and STEREO-B.

During the recent years of deep solar minimum, observers of the sunset grew accustomed to a blank solar disk. News flash: The sunspots are back. “The sunset conditions of August 2nd were just right to show the massive sunspots AR1260, AR1261 and AR1263 to the casual observer who happened to glance at the sun for a brief few moments,” reports Stephen W. Ramsden of Atlanta, Georgia. “You could even see the penumbra with the naked eye!” He had a camera handy and snapped this picture:



Even when the sun is dimmed by low-hanging clouds or haze, focused sunlight can still damage your eyes. Do not look at the sun through unfiltered optics of any kind. A safely-filtered White Light Solar Observing System is the best way to monitor these great sunspots. (SpaceWeather)





CLASSIFICATION OF X-RAY SOLAR FLARES:
A solar flare is an explosion on the Sun that happens when energy stored in twisted magnetic fields (usually above sunspots) is suddenly released. Flares produce a burst of radiation across the electromagnetic spectrum, from radio waves to x-rays and gamma-rays. [more information]
Scientists classify solar flares according to their x-ray brightness in the wavelength range 1 to 8 Angstroms. There are 3 categories: X-class flares are big; they are major events that can trigger planet-wide radio blackouts and long-lasting radiation storms. M-class flares are medium-sized; they can cause brief radio blackouts that affect Earth’s polar regions. Minor radiation storms sometimes follow an M-class flare. Compared to X- and M-class events, C-class flares are small with few noticeable consequences here on Earth.
Each category for x-ray flares has nine subdivisions ranging from, e.g., C1 to C9, M1 to M9, and X1 to X9. In this figure, the three indicated flares registered (from left to right) X2, M5, and X6

[FONT=Arial, Helvetica, sans-serif]ONE DOWN, TWO TO GO: [/FONT]As predicted by analysts at the GSFC Space Weather Lab, the first of three CMEs produced by the recent spate of flare activity reached Earth during the late hours of August 4th. The impact was weak and is not expected to produce strong geomagnetic storms. Two more CMEs are still on the way and, as described below, they may have merged into a single cloud that could produce significant storming when they reach Earth on August 5th around 10:00 UT. A new model of all 3 CMEs is now available; stay tuned for updates.




[FONT=Arial, Helvetica, sans-serif][/FONT]
[FONT=Arial, Helvetica, sans-serif]STRONG SOLAR ACTIVITY: [/FONT]For the third day in a row, active sunspot 1261 has unleashed a significant M-class solar flare. The latest blast at 0357 UT on August 4th registered M9.3 on the Richter Scale of Flares, almost crossing the threshold into X-territory (X-flares are the most powerful kind). The number of energetic protons around Earth has jumped nearly 100-fold as a result of this event.



The eruption propelled a bright coronal mass ejection (CME) toward Earth. Click on the image to view a movie of the expanding cloud recorded by the Solar and Heliospheric Observatory:

Note: The many speckles in this movie are caused by energetic solar protons hitting the camera.​

Moving at an estimated speed of 1950 km/s, this CME is expected to sweep up an earlier CME already en route. Analysts at the GSFC Space Weather Lab say the combined cloud should reach Earth on August 5th at 10:00 UT plus or minus 7 hours: "The impact on Earth is likely to be major. The estimated maximum geomagnetic activity index level Kp is 7 (Kp ranges from 0 - 9). The flanks of the CME may also impact STEREO A, Mars and Mercury/MESSENGER." High-latitude sky watchers should be alert for auroras.
