สรุป

วันที่ 6 มิถุนายน 12 - มีการระเบิดระดับ M class (ระดับปานกลาง)
จากจุดดับ 1494 ซึ่งมีพิกัดอยู่ที่ S17 E06

และจุดดับ 1493 พิกัด N12 W05 ถ้าเทียบกับโลกก็แนวๆ ทางประจวบเพชร ชลบุรี ระยอง จันทบุรี ตราด (ประมาณนั้น)

ก็รอไปประมาณ 3 วันว่าจะมีผลกระทบกับเราอย่างไร

 

M-Flare + CME
6/7/2012 by Kevin VE3EN at 01:55 UTC



Updated 6/7/2012 @ 01:55 UTC
M2.1 Solar Flare
Sunspot 1494 located in the southern hemisphere just produced a moderate M2.1 solar flare. [Movie]. The latest event peaked at 20:06 UTC Wednesday afternoon. The event itself was not long in duration. I will provide further updates if needed.


UPDATE: The M-Class flare from earlier today did produce a Coronal Mass Ejection. This image by STEREO Ahead COR2 from a side view of the Sun indicates that a majority of the cloud is headed south. There may be a small portion that could be Earth directed. Stay tuned for further updates.

การระเบิดขนาดปานกลาง M2.1 จุดดับ 1494 ที่อยู่ทางใต้ของดวงอาทิตย์ ได้ทำให้เกิดแฟร์ลูกปานกลาง สูงสุดประมาณ 20.06 UT - ตีสามเมืองไทย วันที่ 7 มิถุนายน การระเบิดไม่ได้เกิดขึ้นนาน

M-Class นี้ทำให้เกิด CME และส่วนใหญ่มันไปทางใต้ และจะมีบางส่วนตรงมายังโลก ให้จับตาดูกัน

The Venus transit of the Sun was not visible in Belgium because it happened for the biggest part during the night and because of the bad weather this morning. But, the rare phenomenon was recorded from beginning to end by a Belgian instrument onboard the satellite PROBA2.​

On June 5th-6th 2012, a Venus transit of the Sun took place.It was visible as a black circle crossing the solar disk. From Belgium, we could only see the transit for a short period, as it was nighttime in Belgium for the majority of the transit, and it was only visible very early this morning. However, the ESA satellite PROBA2 observed the transit from the beginning to the very end from a front row seat in orbit! The event was recorded by SWAP, a Belgian EUV telescope onboard PROBA2 which filmed this rare event. We will have to wait until 2117 for the Earth, Sun and Venus to line up again. So, the next Venus transit will take place in 105 years!​

PROBA2 in the perfect position to observe the Venus transit

On June 6th 2012, at 0:03 Belgian time, Venus seemed to touch the Sun before starting its transit. At 5:31 Belgian time, the Sun started to rise in Ukkel. It took a little bit longer before the Sun was high enough above the horizon to spot Venus. At 06:56 Belgian time, the black disk of Venus disappeared from sight. But, the micro-satellite PROBA2 orbiting the Earth at a height of 700 km, could observe the Venus transit completely. The hours of first and last contact differ however a little: from the point of view of PROBA2, Venus commenced its transit of the Sun on June 6th at 00:17 Belgian time and finished by 6:50 Belgian time.

Does Venus move up and down - or not?

In simulations as well as in the SWAP EUV movie, Venus seems to move up and down on the solar disk. This can be explained by PROBA2's orbit around the Earth from the North Pole to the South Pole and back to the North Pole. The satellite thus observes the Sun sometimes from 'above' and sometimes from 'below' the Earth. This creates the illusion that Venus moves up and down in the images, but in fact it is PROBA2 that is moving up and down. ​

Scientific results

The Venus transit was an opportunity for the scientists of the Royal Observatory of Belgium to check out their telescopes and calculations. Since Venus 'touched' the Sun exactly at the predicted time, they obtained re-assurance that PROBA2's orbit is accurately known.

The contrast of the images is limited by stray light in the telescope. Ideally Venus should block all the sunlight and should have appeared completely black. By measuring the amount of (undesired) light in the 'Venus spot', we learned a lot about the stray-light in the SWAP optical system.

When the transit was finished, SWAP followed Venus by pointing away from the solar disc and taking pictures of the upper solar atmosphere - also known as the solar corona - (This is not shown in the movie). Due to the low brightness of the corona in the background, Venus gradually 'faded away'.​

HUBBLE TRANSIT OF VENUS: One of the big ironies of the 2012 Transit of Venus was that NASA's greatest telescope didn't dare photograph the event. Hubble's instruments are so sensitive, one look at the glaring sun would have crippled its instruments. Nevertheless, Hubble managed to join the show. Astrophotographer Theirry Legault caught the observatory flitting in front of the sun alongside Venus:

​

​

"I was in north-east Australia for the full transit of Venus and a transit of Hubble in the middle," says Legault. "My Nikon D4 digital camera was working at 10 fps on a Takahashi FSQ-106ED telescope to record 9 images of HST during its 0.9s transit."

​

This is certainly an historic photo. Imagine what James Cook would think of a telescope in space crossing his field of view as he watched the transit of 1769 from a beach in Tahiti. Moreover, imagine what kind of telescopes will be crossing the sun when the next Transit of Venus occurs in 2117. Congratulations to Legault for capturing a truly rare 0.9s slice of history.​
