Hi all,

I've got 5 meteor reports from September. The alfa Aurigids were not great this year. Delta Aurigids were also present in low rates, never higher than 1-2 meteors in one hour.But I find that this shower produce many nice meteors. Sporadic rates were high during the second half of the month with many activity from the constellations Aries, Perseus, Triangulum and the apex source. No suspicious radiants were observed. Enjoy the reports! M.
