Did you have phone problems on Thursday night? This might be why

This burst of solar activity began at 8:27pm last Thursday night, and NASA says it disrupted radio communications after 9pm.

IF YOU HAD difficulty trying to tune a radio – or using your mobile phone – on Thursday night, this might be the reason why.

NASA’s Solar Dynamics Observatory has released this photo of a sun spot from November 3, which led to the emission of a giant solar flare which passed by us later that night.

The solar eruption happened at around 8:27pm Irish time, NASA says, resulting in disruptions to radio communications on planet Earth around 45 minutes later.

NASA classed the flare – which is officially named AR1339 – as ‘an X 1.9-class flare’, which ranks it among one of the larger types of solar emissions.

Another eruption – a ‘coronal mass ejection’ – began at 1:45am on Thursday morning, but came off the opposite side of the sun and so did not come towards Earth.

NASA can track solar activity in all directions thanks to a fleet of spacecraft watching our nearest star from all sides. The two largest such spacecrafts – the conveniently-named Solar TErrestrial RElations Observatories (STEREO) – are on directly opposite sides of the sun.

  • I have problems with my phone EVERY night ! Does anyone here feel that the standard of mobile phone reception is getting poorer ? I live in the south-west and would estimate the I “drop” 50% of my calls. I feel this is either caused by poor coverage or possibly the newer “smart phone” handsets have weaker reception. Any thoughts ? It’s cracking me up !

  • It’s absolutely unbelievable how we, a species, a nation, even down to a community, with our so high dependence on technology in the modern day cannot have in place an effective framework of co-ordinated early warning systems to notify the public of any abnormal phenomena, foreseeable or predictable, with suffecient time allowed for people to make preparations or counter-measures. It baffles me how we are so reactive instead of proactive still today!
    This article highlights how solar activity can affect our communications capabilities for example, an incredibly valuable framework we so highly depend upon and yet we have no measures in place to either protect it nor a contingency plan in place should it fail..

      You cant exactly predict solar flares or coronal mass ejection’s much in advance, so your point is invalid. And there is a threat from these phenomena, a direct hit from a large cme could knock out all communication systems on this planet, the thing is, we wont get much warning.

    • True Sean although we cant claim that victory two weeks ago in dublin unfortunately. That said look at Asia or South America where floods, earthquakes etc. can affect or kill by the hundreds or thousands and yet their culture is accustomed to it because they know they’ll be coming into monsoon season everytime.
      Also true Orion about solar activities but look at dublin or cork two years ago both incidents could have been prevented or contained given we know when the highest astronomical tides occur, both in April & October, and yet incompetence ignored it resulting in the damage caused that the unfortunates are still paying for today.. opening sluice gates at HW when a dam is about to collapse? the water has to go somewhere..
