The WMAP Cold Spot or CMB Cold Spot is a region of the sky seen in microwaves which analysis found to be unusually large and cold relative to the expected properties of the cosmic microwave background radiation (CMB). The typical fractional temperature fluctuations of the CMB are of order 10-5, and the "cold spot" is approximately 70 µK colder than the average CMB temperature (approximately 2.7 K). The radius of the "cold spot" is about 5°; it is centered at the galactic coordinate lII = 207.8°, bII = 56.3° (equatorial: = 03h 15m 05s, = -19° 35 02 . Thus it is in the Southern hemisphere of the Celestial sphere, in the direction of the constellation Eridanus.
