Jan 16/17/18 Meteors

A steady shower of meteors continues to fall on Tucson, night after night. Even with a still very bright Moon, the cloud-less sky is allowing almost two dozen meteors to be detected nightly.

Last night, the best meteor was the one shown below. Occurring at around 9:11 UT, it was extremely slow (taking 3.8 seconds to move ~30+°) and bright (magnitude ~-1). The stars that it passes by in the lower left of the frame are the bowl of the Big Dipper. The bright thing just outside the upper right edge of the FOV (and causing the oval reflections near the top and bottom) is the Moon.

Though unrelated to the meteor above, four other meteors appeared to radiate from a point just to the southeast of the Beehive (M44) in Cancer. It is possible that these meteors are related to the Northern Delta Cancrids (NCC) even though the MetRec software only attributed one to that shower (the other four were assigned to the Antihelion (ANT) region which is very close as well).
