185. Midnight Sun
On December 21st I posted a picture taken in the middle of the day to show how dark it was. To balance it out, here is a picture taken in Deering in the middle of the night on the longest day of the year. (Chip e-mailed it to me. He is not sure why the sun came out black.)

the black sun (if this was taken with a digital camera) is a result of intensity thresholding. The sun is too bright for the CCD (charge coupled device) that registers photons in a digicam, so it sets a "threshold" for maximum light intensity in an image and anything above that goes to black. (this happens to my cells if I overexpose them with the fluorescence camera)
