The north-eastern horizon as seen from Adelaide at 5:00 am ACST, the
eta Aquariid radiant is marked with a starburst. Related views might be
seen elsewhere in Australia on the equal native time (click on to
embiggen).
The eta Aquariid meteor bathe, which is produced by the particles from Halley’s Comet, will peak
on Might 6 (strictly talking Might 5, 21UT).
The moon is sort of new, so the charges might be barely higher away from the nominal peak on the sixth because the Moon wanes. There was predictions we would have the next charge this 12 months, so it’s worthwhile to look out on the weekend mornings of Might 5,
Might 6, Might 7, and Might 8 from 3:00 AM to five:00 AM native time Australia-wide,
the place folks with darkish skies ought to see a meteor round each three to 4
minutes.
Individuals within the suburbs
ought to see a meteor round as soon as each 6 minutes,
and within the nation about as soon as each 3-4 minutes. The radiant of the
bathe is about 5 hand-spans up from the japanese horizon, and three
hand-spans to the left of due east at 4 am (see spotter chart at 5:00 am
above). The radiant is near Saturn, which makes a great reference level.
Weather prediction looks okay.
You could have learn that this 12 months the eta Aquariids have a predicted ZHR of 40 meteors. The determine ZHR is zenithal hourly rate. That is the variety of meteors
{that a} single observer would see per hour if the bathe’s “level of
origin”, or radiant, had been on the zenith and the sky was darkish sufficient
for six.5-magnitude
stars to be seen to the bare eye.
In observe, you’ll by no means see this many meteors because the radiant might be
a long way beneath the zenith.
Additionally, until you’re out deep within the countryside, the darkness might be
lower than superb. What number of are you prone to see in actuality?
The desk beneath provides predictions
beneath for numerous cities, however they’re solely predictions and whereas based mostly
on common steam density there could also be some variations 12 months to 12 months, however
good charges
had been
seen in earlier years, and darkish sky websites might probably see one meteor
each 3-4
minutes or so. There have been many shiny ones reported with persistent
trains in 2014. Individuals within the suburbs perhaps will see much less,
however at the least one each 6 minutes ought to be doable.

The
radiant of the bathe is about 5 hand-spans up from the japanese
horizon and three hand-spans to the left of due east at 4 am (see above
for a spotter chart at 5 am). When wanting, make sure to let your eyes
regulate for at the least
5 minutes so your eyes may be correctly tailored to the darkish.
Do not look
immediately on the radiant web site, as a result of the meteors will typically begin
their “burn” a long way from it, however round a hand-span up or to the
facet. One of the best ways to look at the Eta Aquariids is to let your eye rove
round
your entire patch of the sky above the north-east horizon, between the
solely two apparent shiny stars within the northeast, Altair and Fomalhaut,
and Saturn as the middle of your discipline (once more, see the spotter chart at 5:00 am
above).
Be affected person, though it’s best to see an common of
a meteor each 6 to eight minutes, a complete stretch of time can go by
with out a meteor, then a complete bunch flip up one after the opposite.
Make
your self comfy, select an observing web site that has little to
hinder the japanese horizon, have a snug chair to take a seat in (a
banana lounger is finest), or blankets and pillows. Rug up in opposition to the
chilly. A sizzling Thermos of one thing to drink and loads of mosquito
safety will full your observing preparations. In addition to
meteors, maintain a watch out for satellites (see Heavens Above
for predictions out of your web site). The Milky means will arch above you,
with Saturn simply subsequent to the radiant.

You
have to select 31 Eta Aquariids and keep in mind to set the date to 5-6 or 7-8 Might 2024 and switch off daylight saving time. You may observe the progress of the bathe on the IMO live Aquariid site.
