blank sun
© SOHOThe sun has looked remarkably blank lately; a sign that Solar Minimum is coming.

August 28th, today. But it could have been taken on any day of the past seven weeks. For all that time, the face of the sun has looked exactly the same--utterly blank.

According to NOAA sunspot counts, the longest string of blank suns during the current solar minimum was 52 days back in July, August and September of 2008. If the current trend continues for only four more days, the record will shift to 2009. It's likely to happen; the sun remains eerily quiet and there are no sunspots in the offing. Solar minimum is shaping up to be a big event indeed.
