ANNUAL METEOR SHOWERS
*** Jan. 4 Quadrantids: Radiant--Bootes. Very short lived shower,
less that one day. Variable rate, but generally around 60 per hour.
Speed 41 kps and bluish color.
*** Jan. 16 Delta Cancrids: Radiant--just west of Beehive. Minor
shower, rate about 4 per hour. Very swift.

one or two per hour, but among fastest meteors known--65 kps.
*** Feb. 26 Delta Leonids: Radiant--midway in Leo's back. Feb. 5 to
Mar. 19 with peak in late Feb. 5 per hour at 24 kps.
*** Mar. 16 Corona-Australids: Radiant--16 hr 20 min, -48 deg. 5 to 7
