A brace of knock-down solar flares recently exploded " almost simultaneously " from two different sunspots turn up on opposite hemispheres of our star . The extremely rare phenomenon , cognize as a sympatheticsolar flare , is another reminder thatwe are fast approaching the volatile summit in the sun ’s 11 - year cycle , known as the solar maximum .
On Jan. 22 , at around 10:30 p.m. ET , the two solar flares exploded at almost the exact same time fromsunspotsAR3559 and AR3561 , which , at the clip , were separate by around 310,000 mile ( 500,000 kilometre ) — farther than the average distance between the moonshine and Earth , according toSpaceweather.com .
Two solar flares exploded from sunspots on opposite hemispheres of the sun on Jan. 22.
The flares had a combined great power equivalent to a M5.1 order of magnitude flair , the 2nd most herculean year of flarethe suncan produce . The combust twin flares also launched a wave of high - energy particle toward Earth that triggered a 30 - minute radio set blackout above Indonesia and parts of Australia when it slam into our satellite ’s magnetic field , according to Spaceweather.com .
Solar flare pass can also launch tight - moving clouds of magnetic plasm into outer space , known ascoronal mass ejections(CMEs ) , which can barrel into Earth and set off geomagnetic storms that create colourful auroras . But on this juncture , neither flare seems to have free a CME .

Solar flares can occasionally occur inrapid succession from the same sunspot ; this can trigger " cannibal CMEs " if the flare both launch solar eruptionsthat later merge into a bigger solar tempest . But a sympathetic solar flare is a completely different beast .
In the past , researcher assumed that a sympathetic flare was just a freak coincidence . But a2002 studyrevealed that the flare pair are in reality tie together — or more accurately , their sunspot are link up together by massive , unseeable magnetized field cringle that arc around the sun . Therefore , the flares can be considered as two function of a single explosion .
The twinned components of a harmonic flare can be separated by up to 30 minutes , according to the study . It is unclear exactly how much metre elapsed between the eruptions from the late pair , but they were likely split by only a few minutes if not bare seconds , according to footage captured byNASA ’s Solar Dynamics Observatory .
Sympathetic flares are passing rare but they can become more common during solar maximum , when the sun ’s magnetised theatre starts to break down and becomes more entangled with itself , a2022 studyanalyzing 40 years of solar flare data give away .

Solar activity has been chop-chop ramping up over the last 12 months . During this clock time , we have visualise anincrease in the number and sizing of sunspots , as well as more frequent andmore powerful solar flair .
Most late , the sun unleashed a CME on Jan. 20 , which was predicted totrigger a geomagnetic storm that brings aurora to parts of the U.S.on Jan. 23 .
Scientists originally predicted that the solar maximum would get in in 2025 and be weak compared to past maximums . Butmounting evidence to the contraryhas changed their minds — they now think that the Dominicus ’s chaotic peakcould get in the next few month , if it has n’t already .
