2010 Perseid shower
Hi all,
Now is the time to start thinking about the Perseid meteor shower. It will be visible under UK clear skies from now up to its predicted peak on August 12 th. You should be able to see a few per hour from now and with the Moon rising after midnight on the 5 th August and rising later on each morning after and waning all the time so only your site light pollution will hinder you. The number will gradually increase as the max approaches. To find the radiant go outside at 2 30 pm BST and stand with your back to the Sun. The shadow cast by your body points in the azimuth direction of radiant at 10 30 pm BST. The altitude of the radiant is 30 degrees at this time , so 1/3 from horizon to your overhead point.. You will not see the trails start from this point but about 30 degrees away from this point. Remember where they started and where they finished and then draw an imaginary line from the end of the trail to the beginning and extend it further back. You will find that the different trails cross a single point. You will also see some sporadic meteors which are not related to the shower and will appear to come from a different point than the radiant you are watching. Do not forget that over a few hours viewing the radiant moves just as a star does For further help may I suggest you visit cloudbait.com for information of 2009 sightings and other useful points about the Perseid shower. Get well wrapped up it will get chilly laid out on a deckchair etc. All you need is to be comfortable and in a dark location. Perhaps the photographers in the newsgroup could give advise on how to capture on a DSLR camera the trails of them! |

.... (Perseids) Many thanks for posting the reminder. It's prompted me to as a couple of questions. 1. Any recommendations for the best lightweight fold-flat chair for meteor watching? I'd like something that's both light and flat for taking in a motorhome or caravan where weight and storage space are both at a premium. Apart from being too heavy deckchairs are not ideal unless augmented with a pillow, IMHO! I've seen some very lightweight foldable chairs that were much lighter than deckchairs but their backrests don't go back far enough and they had nothing to support a person's head. Anyone found the ideal chair? Perhaps the photographers in the newsgroup could give advise on how to capture on a DSLR camera the trails of them! 2. Some time ago on TSAN they showed a bit of electronics which emitted a sound as a meteor burned up in the atmosphere. Something to do with reflected TV station signals. Anyone know of a prebuilt unit or a good kit to do that? James |

There are some notes regarding radio meteor observation he http://www.popastro.com/sections/meteor/2009/radio.htm There are may types of suitable radio equipment - I use an Icom PCR1000. The analogue TV transmitters used as the targets are getting fewer and fewer, but there are lower power alternatives.
