Sun image taken on 12 Feb 2005

Dear all:

The weather on yesterday was fine and I took some image of sun. The
following are the details of photo:

Telescope: Borg 100ED (F6.4) at 640mm prime focus.
Filter: Badder photographic solar filter
Date: 12 Feb 2005
Object: sun
Location: Roof of Hung Shui Kiu
Mount: Tak P-2
camera: Philips ToUcam Pro
images: stack from 300 raw image with registax 3.01.23

They are sunspot no. 733 (lower right), 734 (middle) and 735 (top left).
Spaceweather.com said "Sunspot 733 is three times wider than Earth. So is
sunspot 735. These 'spots are big, but they have simple magnetic fields
that pose little threat for strong flares. Solar activity should remain
low."

Please feel free to comment

Regards,
mbike
