[FONT=Arial, Helvetica, sans-serif]NIGHT-TIME SOLAR RADIO BURST: [/FONT]The M9-class solar flare of August 4th produced a burst of shortwave static so powerful that receivers on Earth picked it up after sunset. "A RadioJove observer in Florida recorded the burst when the sun was 38 degrees below the horizon," reports amateur radio astronomer Thomas Ashcraft. Ashcraft's own radio telescope in New Mexico recorded the event 1 hour and 54 minutes after sunset:

​

"To my knowledge, receptions like this are very rare," says Ashcraft.


Indeed they are. This event brings to mind the iconic night-time solar radio burst of March 8, 1958. Five radio telescopes at the University of Florida picked up emissions from the sun while observing the planet Jupiter in tthe middle of the night. On the other side of the world, radio astronomers in daylit Australia confirmed that a powerful solar radio burst had taken place at that exact time. The event is described in a 1959 Nature paper by pioneering radio astronomers Alex Smith and Tom Carr.



They considered the possibility that solar radio waves might have been reflected by the Moon or carried to the night side of Earth by ionospheric ducting. In tthe end, they could not conclusively explain what happened and to this day night-time solar radio bursts remain a puzzle.

[FONT=Arial, Helvetica, sans-serif]GEOMAGNETIC STORM IN PROGRESS: [/FONT]A major geomagnetic storm is in progress following the impact of a CME on August 5th around 1800 UT. Sky watchers at all latitudes should be alert for auroras after nightfall. Tip: the best hours for aurora sightings are usually around local midnight. Aurora alerts: text, voice.



Reports of Northern Lights are coming in from many European countries including Germany, Denmark, Scotland and the Netherlands.


Analysts at the Goddard Space Weather Lab say that the CME impact may have strongly compressed Earth's magnetic field, directly exposing satellites in geosynchronous orbit to solar wind plasma. Stay tuned for updates on this aspect of the storm.


The arriving CME left the sun on August 4th, propelled by an M9.3-category eruption in the magnetic canopy of sunspot 1261. 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.​

[FONT=Arial, Helvetica, sans-serif]GEOMAGNETIC STORM: [/FONT]A geomagnetic storm is in progress. It began on August 5th around 1800 UT when a CME struck Earth's magnetic field. At its peak during the hours just after impact, the storm registered 8 on the 0 to 9 "K-index" scale of geomagnetic disturbances, making it one of the strongest magnetic storms in years. The subsiding storm will likely take many more hours to peter out, so high-latitude sky watchers should remain alert for auroras.

Aurora alerts: text, voice.


The timing of the CME impact favored observers in Europe. "For the first time, I have seen Northern Lights from England," reports Marvin Watson of Whitehaven, who took this picture just after local midnight on Aug. 6th:

​

"I spent one and a half hours watching and photographing the aurora across the solway firth towards Scotland," he adds. "It was a wonderful show." Other notable displays occured in Finland, Germany and Poland.

 

[FONT=Arial, Helvetica, sans-serif]M-CLASS SOLAR FLARE: [/FONT]Sunspot 1263 produced an impulsive M3-class solar flare on August 8th at 1810 UT. In Falmouth, Maine, amateur astronomer John Stetson happened to be observing the sun and he caught the sunspot in mid-eruption:

​

"Perhaps we will get some more auroras this week," Stetson wrote hopefully. Alas, no. Although this eruption did hurl a CME into space, the plasma cloud does not appear to be heading for Earth. Further analysis could reverse this conclusion, however, so stay tuned for updates.

 

ระเบิดอีกแล้ว classs M อีกเช่นเคย

 

X classs now !!!!!!!!!! WOWOWOW

 

ต้องรออีกพัก ดูรายละเอียด จะได้รู้ว่ามีผลกระทบกับโลกอย่างไร มันพึ่งจะระเบิดเมื่อกี้เอง

Massive X6.9 Solar Flare:

The largest solar flare of Cycle 24 just took place at 08:05 UTC and it registered a whopping X6.9. The source was Sunspot 1263 which is nearing the Western Limb. Because of its location, any large explosions may not be fully earth directed. When watching new video images from the STEREO website, it appears the CME is less intense than the one caused by the M9.3 flare from last week

Solar flare ที่ลูกใหญ่ที่สุดใน Cycle 24 พึ่งจะเกิดวันนี้ 8.05 UTC (บ่ายสามบ้านเรา) ถูกบันทึกได้เป็น X6.9 มาจากจุดดับ 1263 ที่ใกล้กับฝั่งตะวันตกของดวงอาทิตย์ เพราะที่ตั้งของจุดดับ เมื่อมีการระเบิดครั้งใหญ่ ก็จะไม่ส่งผลตรงมากับโลกมากนัก เมื่อดูจากดาวเทียม STEREO ก็จะเห็นว่าไม่ค่อยมี CME มากเหมือนกับลูกก่อน M9.3 อาทิตย์ที่ผ่านมา

S1 Radiation Storm is in progress.
