The Orionids are a worthwhile bathe that considerably favours the Southern Hemisphere, greatest seen between 2-5 am,
the radiant, the purpose the place meteors seem to originate from, being just below Betelgeuse, the brilliant pink star in Orion. The maps above present the views from Darwin, Brisbane and Adelaide at astronomical twilight (90 minutes earlier than dawn). Comparable views will likely be seen on the equal native time at comparable latitudes (Adelaide stands in for Melbourne, Sydney and Perth)
If you happen to draw an imaginary line between Procyon and Aldebaran, then drop
one other imaginary line from Betelgeuse to the horizon, the radiant is
simply subsequent to the intersection of these two traces.
The Orionids are the particles from Halley’s comet. The Orionids most is on October 21 UT (October 22 Australian time).
This yr the Moon will not intrude with the bathe.
The very best viewing is the morning of the twenty second, when between 3-5 am
below darkish skies you need to see a few meteor each 4-5 minutes,
though affordable charges will likely be seen the mornings earlier than and after
(see desk beneath).
You could find out the anticipated charges to your location utilizing the NASA meteor flux estimator (use 8 Orionids and be sure to set the dates to 21-22 October 2022).
Sadly, each Chrome and Firefox have modified their safety
settings to forestall plugins from operating, and the flux estimator solely
runs below Edge in Web Explorer mode now (an you now need to activate IE mode manually in settings).
You possibly can observe the progress of the bathe on the IMO Orionids live page.
If you happen to resolve to stand up, enable at least 5 minutes to your eyes to regulate, and
be affected person, it could be a number of minutes earlier than you might be rewarded with you
first meteor, then a pair will come alongside in fast succession.
Select a
viewing spot the place you may see a big swathe of sky with out timber or
buildings getting in the way in which, or with street-lights getting in your
eyes.
The darker the spot the higher (however do be wise, do not select a spot
in an unsalubrious park for instance). Look to the north-east, and the
distinctive pink star Betelgeuse beneath the saucepan will likely be simple to identify with vivid Jupiter beneath it.
The meteors ought to originate slightly below Betelgeuse. Nevertheless, let your eyes
roam a bit to choose up meteors that start their “burn” a good distance
from the radiant.
A garden chair or one thing comparable
will make your observing comfy (or a picnic rug unfold on the
floor and a pleasant pillow), and having a Thermos of sizzling espresso, tea or
chocolate to swig whereas watching will improve your consolation. (Here is
some
hints on darkish adaption of your eyes so you may see meteors higher).
The next desk reveals the anticipated peak charges at across the peak most native
time (roughly 2 hours earlier than native dawn on the mornings of the twenty first, twenty second and twenty third of October for a quantity
of
cities below darkish sky situations (charges below suburban or metropolis mild
situations will likely be decrease). Charges will likely be comparable on the identical
latitude as these cities, and charges will likely be intermediate at spots
between these cities.
