Good weather conditions with some high altitude tin clouds. Some
clouds obstructed observations at the beginning of the second night.
Field of view centered in Auriga until 1:00 UT and later between UMa
and Gem, above the head of Leo. ZHR maximum reached between 4:03 and
4:36. ZHR higher than expected. Good meteor show with some bright
meteors -3 (4 meteors) and -2 (9 meteors) observed, and one splendid
fireball of -6 at the end of first night. ZHR is given with r=2.6 and
no radiant altitude correction (h=1).
