This page last updated on September 15, 2009 at 15:19 P.D.T. Observatory weather: clear but with local smoke; winds calm; 68 degrees F.
Most current magnetograph data: 15-Sep-2009.




Today, for the first time since August 28, the 150-foot solar tower at Mount Wilson -- the one with the famous webcam on top -- observed the Sun. (Yesterday was very foggy.)

The Sun was very boring, as it has been for a while now, but that may be about to change.

In spite of the proclaimed success of the controlled burn last week, the section of the fire perimeter from Mount Wilson to the Cogswell Reservoir is the only bit officially marked "not controlled." No-one seems to be very worried, though. The official containment date was to have been today, but they put it back because of the hold-ups last week, and it now stands at 91% contained, still smoking and smouldering in places.

Mission Statement

Reading, writing, plant photography, and the small details of my life, with digressions into science and computing.
