New Å®ÉúСÊÓÆµ often reminds us of the potential damage from large space storms. But far less extreme solar and power grid phenomena can still wreak domestic havoc (6 June, p 14).
Take one occasion where my dishwasher failed to empty, for example. I could find no blockage. Then I realised that flickering lights in my study probably signified an electrical issue caused by a coronal mass ejection at the time. On a hunch, I pulled out the dishwasher, crawled behind it and turned the power off and back on. It has worked properly ever since.
