flares on record.

The so - called Carrington Event of 1859 began with a bright solar
flare and an ejection of magnetized, high - energy particles that produced the most intense magnetic storm ever
recorded on Earth.
That day, satellites in orbit around the Earth
recorded a
flare on the sun, which produced a spike of X-ray emissions.
JUST before noon
on 1 September 1859, an English solar astronomer named Richard Carrington witnessed the biggest solar

flares» in the atmosphere («shooting stars») and acoustical data that
record cosmic impacts
on the surface of the earth, Peter Brown and his co-workers at the University of Western Ontario and Los Alamos National Laboratory estimated the rate of smaller impacts.

recorded its first solar
flare on Tuesday, and the network can now scan the Sun 24 hours a day — at least during the Northern Hemisphere's summer as there are still gaps in the coverage of the Southern Hemisphere.

This new analysis implied that the star actually released a 1 - minute - long
flare, a thousand times brighter than the star's usual shine — perhaps 10 times brighter than the most powerful solar
flares from our own sun
on record, said Weinberger.
Though they usually take weeks or months to reach maximum brightness (and longer to fade away), astronomers recently observed a star called KSN 2015K whose supernova
flared up to max brightness over in just 2.2 days and dimmed to half of that in 6.8 days, placing it among the fastest, brightest supernovas
on record.
[44] In August 2015 the largest
recorded flares of the star occurred, with the star becoming 8.3 times brighter than normal
on 13 August, in the B band (blue light region).
