Woohoooo! Keep those "Likes" coming thru
I've just done another update on the fb page regarding the Lyrids.
Actually this would make it the third update .

LYRIDS METEOR SHOWER-
If you want more information, on the Lyrids meteor showing happening tonight ( & thru the wee hours of tomorrow morning), take a look at this link- it's a beauty! Everything you need to know is here. You can even click on your location to find the best times to view this event. Clear skies everyone, we won't get to see as many as the northerners, but I hope we get us some nice ones!
-Suzy.

Went out for a look at the Lyrids this morning from 4:15 to 1st light and saw about 20 in total. Several of these were quite bright (Mag 0 to -2)
Glad I made the effort with a couple of other Gove Astronomers, who contacted me to see if I was going for a look :-)

might be worth a look and have a go at some photography.
I have a good northern aspect,I could take the mount out and put a Canon 50D with 10-22 mm lens on it,moon should set approx 2.30 am.
What settings would be good,if I want to try and stack them?

Stop it down a bit, take longish exposures and cross your fingers might work..

Cyclone, I have watched, and phototgraphed MANY meteor showers over the years, love them, but the Eta Aquarids has not been high on my list for some reason. Whether I have tried a few times with minimal results, am unsure.
Looking at the info on the net, seems it is worth a watch, and will give them another go.
Have you seen many Ian?
'......Every year, the earliest Eta Aquarids can be seen around April 21 and they persist until about May 12; however, the number of meteors you are likely to see will be low until around the time of the peak on May 5/6. At this time, observers in the Northern Hemisphere are likely to see about 10 meteors every hour, while Southern Hemisphere observers will see about 30 per hour.'

Oh boy Ian, you did well. And if I remember correctly you bagged a ton of Geminids as well!
I had a disappointing session. When I stepped outside for half an hour at 12.30 to see how they were panning out, I saw two (one really bright one) in quick succession. So I waited eagerly till around 2am when the moon went away and Lyra to get higher to go back out there for an hour. Zilch.
Liz those Aquarids sounds exciting. I'm looking forward to it- I've never seen them before.

Hi Liz
I will be back in Cairns observing this year and hope the skies are kind !
Here is an Article I wrote a few years back on the Eta's

Thank you Ian, and good luck. Hope the clouds associated with that Low will have gone.

I was out on Monday night @ 9:30 pm looking east but not expecting to see anything. A metior, bright, yellow-orange colour moving fast from west to east got my attention. Nothing special except it was accompinied by a crackling or hissing noise. What would cause that?

Sounds of meteors
Sound generated by a meteor in the upper atmosphere, such as a sonic boom, is typically delayed for many seconds after the meteor disappears. Occasionally, as with the Leonid meteor shower of 2001,"crackling", "swishing", or "hissing" sounds have been reported,[32] occurring at the same instant as a meteor flare. Similar sounds have also been reported during intense displays of Earth's auroras.[33][34][35][36]
Sound recordings made under controlled conditions in Mongolia in 1998 support the contention that the sounds are real.[37]
How these sounds could be generated, assuming they are in fact real, remains something of a mystery. It has been hypothesized by some scientists at NASA that the turbulent ionized wake of a meteor interacts with the magnetic field of the Earth, generating pulses of radio waves. As the trail dissipates, megawatts of electromagnetic energy could be released, with a peak in the power spectrum at audio frequencies. Physical vibrations induced by the electromagnetic impulses would then be heard if they are powerful enough to make grasses, plants, eyeglass frames, and other conductive materials vibrate.[38][39][40][41] This proposed mechanism, although proven to be plausible by laboratory work, remains unsupported by corresponding measurements in the field.
