sun dogs can appear at 22 degrees, from either side of the the sun - when ice crystals in cirrus clouds are at the right angle to refract prismatic sunlight. they are quite exciting. to check for sundogs location on a hazy day, hold your arm straight in front of you. when your thumb covers the sun, there might be a sundog at your little finger
it might be a long time between sightings...
