Re: Change of Meteor Director

As some of you will already know, I am standing-down as SPA Meteor Director with effect from today's London Council meeting. Dear Alastair, Many thanks for the years of dedication to the SPA's Meteor Section. Although my time as assistant was only relatively brief, it was a great privilege to work ...

However, I'm still quite confused. I find it amazing that a biggish meteorite has been in known existence for apparently many years and yet very little seems to be known about it ? Best wishes from Cliff Hi Cliff, Did you manage to watch the video of Professor Pillinger's talk? It doesn't provide a...

Re: Doorstep Meteorite?

Dear al(L) According to a snippet on Channel 5 TV "Wright Stuff" this morning (15th Feb) a newspaper (not sure which ?) highlighted a Doorstep Meteorite. From the little I heard, the vague report seemed to suggest that the supposed meteorite wasn't the doorstep itself but a big stone placed near th...

Thanks for your posting David, but I think that it will all be over by the time we get to your first listed pass, possibly around 18.00 U.T. this evening. Hi, Yes, I see the more recent predictions on Zarya Phobos Grunt re-entry page support a time around then - daylight, South America - Atlantic -...

Phobos-Grunt Re-entry

Re-entry predictions is never an exact science, but I hope the following is roughly correct. I'd welcome corrections and additional information. The current prediction from Aerospace is that Phobos-Grunt will re-enter the Earth's atmosphere at 15 JAN 2012 @ 19:21 UTC ± 3 hour, with the favoured time...

Today, 12th January 2012, sees the publication of the Committee Stage Report, but at just seven pages it adds nothing and is hardly worth reading.

.... The now Bill proceeds to committee stage - where each clause (part) and any amendments (proposals for change) to the Bill may be debated in more detail within the House of Commons. I'm note exactly clear what a "money resolution" is, but my best guess would be that on the 22nd November 2011 th...

Re: Meteorites from Venus and Mercury ..

We know that bits of Mars and the Moon have been found as meteorites on Earth, but what about bits of Venus and Mercury? If found, would it be possible to identify their places of origin? Hi Brian, It's a very interesting question and there has been work done on this. I'd suggest having a look at t...

Don't we all wish that our skies were so transparent that we could see a LM of 6.3 in moonlit skies (although we would of course have been happy with any clear sky that night) Hi Tony, I sure do. Marco's photographic montage of the 2011 Draconids would be a remarkable achievement even without the M...

Members of Unione Astrofili Italiani Sezione Meteori (UAI-sm) seem to have enjoyed better conditions that we did in the UK and, using a network of video cameras, have derived the preliminary observed Draconid radiant position. See here for their results (in Italian).

It was cloudy throughout the evening of the 8th October here in north-west England. My radio meteor system was running and the Draconids were seen to produce a very rapid increase in counts from 2011 10 08 19:00 UT. The peak of counts occurs during the hour from 2011 10 08 20:00 UT to 2011 10 08 21:...

Re: Radio meteor observing via a Pioneer FM analogue tuner

Can anybody help please? Hi Paul, Well done setting up the meteor system. The VHF FM broadcast band (88 - 108 MHz) is somewhat congested and it can be a real challenge to find a suitable frequency, which has powerful distant stations yet no local stations neither on that channel, nor the adjacent o...

Re: Destination Titan on again (Thursday 2 June)

Just noticed that Destination Titan is on BBC4 at 22.45 this evening. Stars our President, John Zarnecki, and is well worth watching.
