An ice crystal halo around the waxing gibbous Moon set in the winter stars of a January night. The 22 degree halo is most obvious and with a reddish and sharply defined inner rim and a bluish and more diffuse outer edge. But a faint 8 degree halo is also visible, a rare halo sometimes called the Van Buijsen halo. The Moon was in Taurus this night and very close to Mars, shining here just above the Moon. Orion is at lower left; Gemini at upper left; Auriga above the Moon; and Perseus is at upper right
