For the Lyrids Meteor Shower this year, the Moon is going to keep the sky quite light, which will make it much harder to see them.  Saying that, it should still be possible, especially when they are at their peak on the 23rd April.  I say this as I happened to be outside this past Tuesday night, watching the ISS fly over Plymouth, and to my surprise, whilst it was moving through Ursa Major (specifically the Plough part of the constellation), there were 5 or 6 tiny little explosions going off in the sky nearby.  I couldn’t quite believe it really and it put me off watching the ISS (which I always find fascinating!).

I watched for several more minutes and saw several other meteors in the sky, in the general area of the sky off to the left of Ursa Major.  These were not massive meteors as far as I could tell, as you only saw them for a split second, but this was probably due to the almost full moon which was keeping the sky bright and hiding all but the most brightest stars.  These weren’t like the tiny explosions I saw during the ISS flyover, but more meteor like.  I can only presume these were the Lyrids and the first batch I saw were so small and didn’t ‘shoot across the sky’ but burnt up as soon as they hit the atmosphere of the Earth.  The second batch must have been slightly bigger and lasted longer when hitting the atmosphere.  Either way, it was great viewing!

The Lyrids Meteors emanate from the constellation Lyra (hence their name) and they are part of the comet Thatcher that takes about 415 years to orbit the Sun.  The peak of the shower is usually around the 21st to the 24th of April but they can be seen for several days before and after, depending on how lucky you are!  I guess I was very lucky the other night!

Enjoy the Lyrids Meteor Gazing!! 😉

This year the annual Lyrid Meteor Shower should be a great spectacle as the Moon will not be lighting up the sky at all. As long as you are out in the country and have the luck of a clear sky, there should be a perfect view of the meteors. Even in a lighter sky, it should be a good sight.

The height of the shower falls on the night of the 21st April with the average number of meteors spotted per hour being at about 10-20, but it has been known to reach up to 100 meteors per hour! On the nights around the peak night, you should still be able to see the occasional meteor. I had a look last night but unfortunately didn’t see any, mainly because the area of the sky where they seem to originate from (The constellation Lyra near the bright star called ‘Vega’.) was too low on the horizon and was hidden by trees.

The Lyrids are thought to be sand grain sized debris from a passing comet. When they hit the Earth’s atmosphere, they burn up, causing the light streaks in the Sky.  In the past, fireballs have been seen hurtling across the sky during this meteor shower. They are thought to originate from comet Thatcher that has an orbit of 416 years with its path staying practically the same each time is passes through.  This means the debris is always in the path of the Earth which is why it is an annual event.

So fingers crossed everyone gets to see a good few meteors! 😉
