A powerful solar flare could clear the night sky over parts of the US this Halloween weekend.

Nasa’s Solar Dynamics Observatory, which operates the National Aeronautics and Space Administration (NASA) said on Friday that it had recorded a “significant solar flare” emanating from the sun.

Two further blasts included an eruption of solar material, a process called coronal mass ejection, and an invisible swarm of solar energetic particles, which ejected into the Earth, Goddard said.

The harmful radiation generated by solar flares can’t enter the Earth’s atmosphere, or influence man, but can interfere with the atmosphere in the layer where GPS and communication signals are sent.

The hit was considered to be X1 – with the X-Class being the most intense.

In a blog posting, Nasa said the ‘significant’ eruption was classed as X1.

When directed directly to the Earth, these intense beacons may also be accompanied by a massive eruption of solar particles, commonly known as coronal mass ejection.

Nasa’s Solar Dynamics Observatory, which monitors the star’s activity, captured a picture of the eruption at 11.35pm (AEST) on Thursday.

Solar flare

A solar flare is a sudden flash of increased brightness on the Sun, usually observed near its surface and in close proximity to a sunspot group. Powerful flares are often, but not always, (wikipedia)


An aurora , also known as polar lights, aurora polaris, northern lights, aurora borealis, or southern lights, aurora australis, is a natural light display in Earth’s sky, (wikipedia)


The National Aeronautics and Space Administration is an independent agency of the U.S. federal government responsible for the civilian space program, as well as aeronautics and space research. (wikipedia)

Geomagnetic storm

A geomagnetic storm is a temporary disturbance of the Earth’s magnetosphere caused by a solar wind shock wave and/or cloud of magnetic field that interacts with the Earth’s magnetic field. (wikipedia)
