Glad you like it. When I made the first post I hadn’t seen the Yerkes refrator clip. Modern telescopes might be technological marvels but they’re not ‘proper’ telescopes in my book.There are a couple of clips of the amazing Treptow refractor as well, must have been a remarkable thing to see in the flesh.Some of the recommendations in the side bars are good as well. I particularly liked ‘Aimng high’ from 1957 (www.britishpathe.com/record.php?id=34881) on the early Soviet space flights. There is some what even then must have archive footage of Tsiolkovsky and the commentary is just priceless.

Thanks David – there are some cracking items there. My favourites are George Cole’s 14 inch (in 1942) and 18 inch (in 1949) telescopes, and the the 40 inch refractor at Yerkes.Only downside is that annoying Gordon Gin trailer that precedes some items.Go well!Jeremy

Yes David, i noticed that too – wasn’t sure if i misheard or not either at the time.Callum

Did anyone notice the comment re. Centaurus A as being our nearest galactic neighbour – or did I mis-hear?! Some careless editing I suspect – our nearest galactic radio galaxy/ies I believe?

Dear Callum,That explains it. I did know about the detection of neutrinos following the explosion, of SN 1987A.How ever. I didn’t realise that know other’s had been observed since that time.

Yes, I thought it was a good programme too…There is still a lot of work to be done on neutrino detectors. Neutrinos from the Sun were detected in the 1980’s i think, but these detectors are searching for cosmic neutrinos, which are a lot harder to differentiate. They are also trying to work out the direction they are coming from, to try and locate sources.I beleive they have detected neutrinos from supernova 1987A (the Rob McNaught one, in the LMC) – but no others (with any statistical significance).Callum

I was curious about the ship laying the nutrino detector the "Pourquoi pas?" … the "Why not?".Roy

At least Brian Cox wasn’t involved. Thank goodness for small mercies!Gary

The AAVSO data mentioned in an earlier message looks to be in error. SV Ari is still ‘bright’ in the mag. 15’s. Gary

An image of SV Ari taken by Guy Hurst on Aug 3.483 UT using the Sierra Stars robotic telescope can be seen at http://www.britastro.org/robotscope/hurst04.htm when the nova was at mag. V = 15.44.

I’ve put a time series plot by Nick James on the front of the VSS web page, if anyone is interested in how these CV’s fluctuate over short time periods. Click the small image to bring up a larger one. Very latest data from US observers show SV Ari now faded to below mag 17.0V. Is this a precursor outburst after all, or the biggest disappointment since my Mum wouldn’t let me go to the Isle of Wight in 1970 to see Jimi Hendrix?Gary

Paul,You can get a chart for it from http://www.aavso.org/vsp Just type in SV Ari at the top, then choose what type of chart orientation you want, field size etc.The original position measured from Heidelberg plates was thought to be in error. This outburst should give accurate astrometry, although it’s probably just seconds of arc in error (if any) looking at outburst images I have.Gary

Paul,I just Googled "Nova Ari 1905" and its second hit was a paper with an (admittedly close in!) finder chart. Strangly no co-ordinates though.Roy
Posted by Paul A Brierley at 06:52 on 2011 Aug 04
Do you have any finder chart’s showing the location of SV Ari?I might try to get an image using my SPX 200-800 "AG" But unfortunately. I don’t know where to look.

A stack of 5×60 second exposures with a V filter! He uses a 35cm SCT.We have no idea as to how bright it will get, or even if this is a fainter precursor to a major outburst. Only time wil tell.Cheers,Gary
Posted by Paul A Brierley at 17:20 on 2011 Aug 03
Out of reach through my 25cm f4.8. But still very interesting.Out of interest. Do you know the length of David’s exposure?Good luck with any observation’s.
