Predicting daily space weather will help keep your GPS on target

It’s well known that severe space weather events – which are quite rare – can have a negative impact on our use of Global Positioning System (GPS) enabled devices. But our research, published in Geophysical…

Giant sunspot returns – and it’s bigger and badder than ever

The largest sunspot seen in 24 years is rotating back to face the Earth, and it looks to have grown even bigger. Last month, the solar active region known as AR12192 (also known as AR2192 to some of its…

Prepare yourself – wild solar weather ahead

During the early hours of this morning (3:42am AEST) our sun released a strong solar flare. It follows right on the heels of a more moderate flare that was released from the same region of the sun on Tuesday…

Are you a frequent flyer? Solar storm radiation can be harmful

Space weather impacts many modern-day technologies. But one of the most concerning – and least reported – space weather effects is the increased radiation exposure to passengers on commercial long-distance…
How will Earth weather solar storms while the sun flips its magnetic field? NASA Goddard Photo and Video

A solar magnetic reversal means there’s no need to flip out – yet

You may have read the sun’s magnetic field is heading for a change in field polarity - meaning it will flip upside down - and could have ripple effects throughout the entire solar system. So what does…

Huge space storm could disrupt power grids, GPS, flights

The biggest space storm in five years is hurtling towards Earth at more than 2000 km per second. Two bursts of solar wind and plasma - known as coronal mass ejections (CME) - are expected to hit Earth…
