Orionid Meteor Shower, Morning 22 October 2014
The Orionids are a worthwhile shower that somewhat favours the Southern Hemisphere,best seen between 2-5 am, the radiant, the point where meteors appear to originate from, being just under Betelgueuse, the bright red star in Orion.
The Orionids are the debris from Halley's comet.
This year the sky is nicely dark for the shower. The best viewing is the morning of the 22nd, when between 3-5 am under dark skies you should see about a meteor every 4-6 minutes.
You can find out the predicted rates for your location using the NASA meteor flux estimator (use 8 Orionids and make sure you set the dates to 21-22 October 2014).
If you decide to get up, allow at least 5 minutes for your eyes to adjust, and be patient, it may be several minutes before you are rewarded with you first meteor, then a couple will come along in quick succession.
Choose a viewing spot where you can see a large swathe of sky without trees or buildings getting in the way, or with street-lights getting in your eyes. The darker the spot the better (but do be sensible, don't choose a spot in an unsalubrious park for example). Look to the north-east, and the distinctive red star Betelgeuse below the saucepan will be easy to spot. The meteors should originate just below here. However, let your eyes roam a bit to pick up meteors that begin their "burn" a fair distance from the radiant.
A lawn chair or something similar will make your observing comfortable (or a picnic rug spread on the ground and a nice pillow), and having a Thermos of hot coffee, tea or chocolate to swig while watching will increase your comfort. (Here's some hints on dark adaption of your eyes so you can see meteors better).
