De zon is al 2x zonnevlek vrij geweest en dat is volgens een deskundige een teken dat het zonneminimum eerder op komst is dan verwacht.
Goed nieuws voor winterliefhebbers? Laatste sets koude winters vielen rond het zonneminimum (85,86 en 96,97)
October 18, 2004: Six … long … years.
Solar physicist David Hathaway has been checking the sun every day since 1998, and every day for six years there have been sunspots. Sunspots are planet-sized "islands" on the surface of the sun. They are dark, cool, powerfully magnetized, and fleeting: a typical sunspot lasts only a few days or weeks before it breaks up. As soon as one disappears, however, another emerges to take its place.
Even during the lowest ebb of solar activity, you can usually find one or two spots on the sun. But when Hathaway looked on Jan. 28, 2004, there were none. The sun was utterly blank.
It happened again last week, twice, on Oct. 11th and 12th. There were no sunspots.
"This is a sign," says Hathaway, "that the solar minimum is coming, and it's coming sooner than we expected."
