Solar flare stops satellites in China

A solar flare the size of Jupiter erupted a few days ago and is now causing radio and satellite signals to drop out in China.

On Valentine’s Day, the sun had a coronal mass ejection associated with a flare, a burst of solar wind that speeds through space.

The ejected material is usually plasma and electrons, though sometimes helium and oxygen are also expelled. It was an X-class, the highest of all classes.

Let’s just enjoy for a moment the phrases Valentine’s Day, coronal mass ejection and X-class.

Anyway, the flare headed to Earth at 900 km per second, and the shockwave of it hitting us has caused a geomagnetic storm that messes with magnets.

It can also cause stunning auroral colours, like the Northern Lights, which have already been seen further south than usual. NASA is warning the flares will keep coming for a couple of days.

Long-lasting solar storms can cause electricity grids to stop working, causing black outs. Much of our technology is dependent on magnets – phones, credit cards, even hard discs when in use. One of my pet apocalypse theories is that a solar flare, or other strong magnetic space event, will wipe out computers and take with them electricity, water and money.

But clearly if your reading this, that hasn’t happened. So just continue to enjoy the phrase coronal mass ejection. Lolz.

    One of these days I’m going to catch an X-Class on NOAA centre for space weather predication and heat up to 50/60˚ latitude to catch some ionospheric puddles 🙂
