(meteorobs) Nice QUA display from South-Eastern France, too

Hi all,

Just to confirm the impressions expressed by Francisco. I observed the shower from Provence, near Manosque (South-Eastern France). The observing session report has been sent to the IMO, for those interested.
I managed this morning to observe 1h Teff in a hole between two clouds waves, just after moonset. lm was quite good, with a +6.3.
Rates were really good, as I could observe 50 Quadrantids in 1h, most of them being quite bright, althought I couldn't spot a single fireball. Some periods appear to be very busy, with sometimes up to 4-6 QUA in tens of seconds intervals, and other time less interesting (2 QUA in a 5 minute-period).
And, special thought to Richard, I wondered, going back home, if I really pushed the "Record" button of my recorder, or only "Play" one... Fortunately, I didn't made the mistake, but I nearly convinced myself I did not record anything while going back home, and I can understand what you feel now ;-)

I did not observe a lot the Quadrantids by the past, but I must say I was really nicely surprised by the display I saw this morning! I hope some other could catch the show!

Clear skies to all, and Happy New Meteor Year!
