Prominent, even from 150 million kms, is this solar prominence

Friday, 10 December, 2010

The recent solar prominence – a large, bright, outpouring from the Sun’s surface – has been estimated to be anywhere from 700,000 to one million kilometres in length. Earth would barely rate as a speck on the above image, possibly being about the size of the little dark circular area that is just visible on the flare, towards the lower left hand side of the image.

We are some 150 million kilometres – give or take – from the Sun, which makes for a reassuring buffer in situations like this.
