|Every year the
at Warren Wilson College photographs the sun looking through a
telescope to examine sunspots, and we usually see several. This
week, however, we could only find one sunspot. The lonely sunspot
is located at about "8:00 o'clock" in the photo about halfway from the
center of the image to the limb or edge of the sun's disk.
The photo at right, taken exactly two years ago today (Sept. 22, 2004) by Simon Johnson shows a much larger sunspot in approximately the sameplace in the image. Finally, below is an enlargement of that major sunspot from two years ago.
All these phoros were taken with a digital camera attached to the eyepiece of an 8-inch telescope. The telescope was fitted with a special filter that blocks out most of the blinding sunlight, otherwise the detector in the camera would be ruined.
