ORIONIDS 2006, VISUAL
The Orionids surprised with heightened activity in 2006.
A considerable set of 146 observing priods was collected
by 2006 October 25, 14h UT which leads o the below ZHR
profile. The maximum was not sharp; high rates were ob-
served throughout the European and most of the American
night of Oct 21/22 with ZHR > 50. Large fractions of
bright Orionids were reported by the observers. A popu-
lation index of r=2.0 was assumed for that reason. Such
a value is typical for strong showers like the Perseids
or the Geminids. Sporadic meteors, for comparson, have
a population index of roughly 3 implying a larger frac-
tion of faint meteors. The Orionids used to have inter-
mediate population indices in previous years.

Solar longitudes refer to eq. J2000.0. nINT is the number
of observing periods in each average, nORI is the number
of Orionids in each average.
We are grateful to the observers who sent in their data
swiftly after the observation was made:"
