(meteorobs) observation report VANMC 21-22 may

[Michel Vandeputte]

Hi, 

I had a 2.5 hour long session under a splendid  (Lm 6.5 -6.6) dark sky. Activity was pretty high and surprisingly I noticed activity from the Tau Herculid meteor shower. I observed 2 slow shower members with a radiant  in the surroundings of Arcturus (alfa Booti). At 23.52 UT I saw a fast -2 apex sporadic with very long trail in the big dipper. Top of the bill ; at 00.29 UT a slow -4 sporadic fireball in Libra. 

A very enjoyable night ! Please enjoy the meteor data ;
