The flare was accompanied by a coronal mass ejection that missed Earth.

A surprise solar flare has burst from an area of dense magnetism on the sun's surface, causing a temporary radio blackout in parts of Australia and all of New Zealand.The M5-class, medium-strength
solar flare was
recorded by NASA's Solar Dynamics Observatory as it erupted from the sunspot AR3141 at 7:11 p.m. ET on Sunday (Nov. 6). The flare created a rush of radiation that ionized Earth's atmosphere, according to
spaceweather.com.
Sunspots are dark regions on the sun's surface where powerful magnetic fields, created by the flow of electrical charges, knot into kinks before suddenly snapping. The resulting release of energy launches bursts of radiation called solar flares and explosive jets of solar material called
coronal mass ejections (CMEs). A CME did accompany this flare, but it was not aimed at Earth.
The solar flare erupted unexpectedly and took scientists by surprise. "Our apologies there was no alert for this event. The flare was impulsive," the solar activity tracking website
SpaceWeatherLive wrote on Twitter.
The
National Oceanic and Atmospheric Administration (NOAA) classifies solar flares in five categories — A, B, C M and X — based on the intensity of the
X-rays they release, with each level having 10 times the intensity of the last. TK
