Australian Perseid Meteor Shower - Morning August 12-14, 2018

% of readers think this story is Fact. Add your two cents.

You can check predictions for your local area at the NASA meteor flux estimator (choose 7 Perseids and 12-13 or 13-14 August 2018). Unfortunately, both Chrome and Firefox have changed their security settings to prevent plugins from running, and the flux estimator only runs under Internet Explorer now.

People around the latitude of Darwin have the best chance of seeing meteors, possibly as many as one every 3 minutes at the peak (see table below). Next are places with the latitude of Alice Springs (around a meteor every 6 minutes), Cairns is intermediate between Darwin and Alice Springs. At the latitude of Brisbane you will see a meteor every 10 minutes (again,see table below).

To see the meteors, you will need to be up from around 3:30 am local time on the morning of the 12th, 13th or 14th (yes, a really horrible hour of the morning), with best views 4:00 am-5:30 am on the 13th. The meteor shower will be located due North, with the radiant just above the northern horizon (see charts above). Cloud cover predictions can be found at SkippySky.

When you 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).

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 adaptation of your eyes so you can see meteors better).

The following table show the predicted peak rates at around 5 am local time on the mornings of the 12th, 13 and 14th of August for a number of cities under dark sky conditions. Rates will be similar at the same latitude as these cities, and rates will be intermediate at spots between these cities.

Town	Morning August 12	Morning August 13	Morning August 14
Alice Springs	7 meteors/hr	10 meteors/hr	9 meteors/hr
Brisbane	4 meteors/hr	6 meteors/hr	5 meteors/hr
Darwin	15 meteors/hr	24 meteors/hr	20 meteors/hr

Rates on the morning of the 15th are similar to that of the 14th. Note, those of you who have Stellarium, in version 13 they have added meteor shower radiants (rates set in the planets dialogue, F4). However while the radiants are shown, the simulated meteors come from random points in the sky, not the radiants.
