Hi Phoenicids observers!
I headed up during the first half of last night, and could only observe clouds from below for a few hours...
Bad luck here in South-Eastern France!
I hope you got better skies!
Karl

Heads up if you are in a favorable location!
The *December Phoenicids (PHO)* are a periodic shower that rarely
produces noticeable activity. The only impressive display produced so
far by this shower occurred in 1956 when ZHR's were near 100. There is
the possibility that in 2014, that the Earth may encounter strong
activity from the Phoenicids. A prediction by Mikiya Sato and Junichi
Watanabe indicates the the Earth will pass through several dust trails
of asteroid 2003 WY25 (formally comet D/1819 W1 Blanpain) between the
hours of *23:30 December 1 and 01:30 December 2 Universal Time*. This 2
hour bracket of time favors much of the populated regions of the world
except those bordering the Pacific Ocean and eastern Asia. The most
favorable locations are South America and Africa where the radiant lies
high in the sky at the time of the expected maximum activity. Normally
the Phoenicid radiant lies far to the south in the constellation of
Phoenix. The radiant position for this outburst is actually located
further north at 00:32 (020) -27. This position lies in northern
Sculptor, 10 degrees southwest of the 2nd magnitude star known as Diphda
(Beta Ceti). At only 10 km/sec. the Phoenicids produce extremely slow
meteors.
