ARLA/CLUSTER: A maior "labareda" Solar registada em 2016

[João Costa > CT1FBF]

Provavelmente terá relação com a "chuva de estrelas" das Perseidas ou
então é mesmo um meteoro desgarrado, no entanto, pela aparência o
"bolide" teria já umas dimensões consideráveis.

>> Strongest flare of 2016
>>
>> The Space Weather site reports sunspot complex AR2565-AR2567 erupted
>> on July 23, twice, producing two strong solar flares in quick
>> succession
>>
>> The first at 0211 UT registered M5 on the Richter Scale of Flares.
>> The second at 0516 UT registered M7.6, making it the strongest flare
>> of 2016 so far.
>>
>> Pulses of radiation from the two flares ionized the top of Earth's
>> atmosphere, causing a blackout of shortwave radio transmissions over
>> the Pacific side of Earth. People who might have noticed the fading
>> signals include ham radio operators, mariners and aviators.
>>
>> The explosions hurled an impressive CME into space. The body of the
>> cloud will not hit Earth. However, Earth could experience a glancing
>> blow from shock waves on the outskirts of the cloud. This has prompted
>> NOAA forecasters to issue a minor geomagnetic storm warning for July
>> 26.
