Gedeeltelike sonverduistering Vrydag, 15 Januarie.


Net so `n katspoegie van `n verduistering. Die enigste vir 2010 hier in die Suide. Op die voorstelling wat met TheSky 6 gemaak is kan mens sien hoe die gedeeltelike verduistering Vrydag om 07:30 gaan lyk. Dit begin om 06:58, bereik sy maksimum om 07:30 en eindig om 07:59. Venus is regs bo in die prentjie.

Is die seisoen vir Sonvlekke hier? Het die gety gedraai?


Sunspot 1040 is busy growing again. In only 24 hours, it has expanded from a barely visible "sun-speck" to a planet-sized active region with 15 dark cores and a tangled magnetic field. Steve Riegel sends this picture from his backyard observatory in Santa Maria, California.
