What are the four classes of solar flares?
What are the four classes of solar flares?
Scientists classify solar flares according to their X-ray brightness, in the wavelength range 1 to 8 Angstroms. Flares classes have names: A, B, C, M, and X, with A being the tiniest and X being the largest.
What is the strongest solar flare?
At 4:51 p.m. EDT, on Monday, April 2, 2001, the sun unleashed the biggest solar flare ever recorded, as observed by the Solar and Heliospheric Observatory (SOHO) satellite. The flare was definitely more powerful than the famous solar flare on March 6, 1989, which was related to the disruption of power grids in Canada.
What is an M-class flare?
M-class flares are medium-sized; they generally 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. A solar eruption.
What was the last solar flare?
Space weather facts
| Last X-flare | 2021/07/03 | X1.59 |
|---|---|---|
| Last M-flare | 2021/08/28 | M4.79 |
| Last geomagnetic storm | 2021/09/17 | Kp5 (G1) |
What is the least powerful solar flare?
The A & B-class are the lowest class of solar flares. They are very common and not very interesting. The background flux (amount of radiation emitted when there are no flares) is often in the B-range during solar maximum and in the A-range during solar minimum.
Are solar flares rare?
Solar flares that reach or even surpass the X10 class are however very rare and occur only a few times during a solar cycle. The coronal mass ejections which can be launched by such solar flares are known to be able to cause issues with our modern technology like satellites and power lines.
What are the side effects of solar flares?
Strong solar flares can send huge clouds of plasma into space. This is known as a coronal mass ejection (CMEs), and when they hit the Earth they can cause geomagnetic storms and intense aurora.
