Observer
NameRobert H
Experience Level4/5
RemarksThe first fall was from the altitude of Rigel and perhaps 10 degrees to the west of that star, using my outstretched fist as 10 degrees. The second fall, 4-5 sec later, was entirely white, had no train and no explosion, was from the altitude of Sirius and 15 degrees farther to the west. I was facing due south as I took down my telescope, the sky being too hazy to observe overhead or to the east any more. The southern sky was clearer.
