UK balloon visible at long range?
Sorry its a little off-topic for this NG
but according to today's Daily Mirror the QinetiQ1 ballon when/if it reaches 132,000ft [25miles] - it should be visible from 300 miles from St Ives Cornwall over 11 hour flight - ballon larger than Empire State Building - NY. Perhaps this could be a good target for distant astronomers for a photo? Worth a tryg. I make London, Sheffield, Liverpool, Douglas IOM and maybe Belfast within 300 mile radius assuming a perfectly clear horizon. The best I've done for a modest weather balloon is 40miles range via my scope whilst scanning for Mercury at pre-dusk. Just a word of caution regarding Daily Mirror fact - yesterday they said crew would wear spacesuits to withstand -700C !!!! Parky |

Parky That is presumably -70 degrees centigrade, with the degree sign fallen and expanded. Had it been Celsius, the problem should not have occurred. For a height of 40 km, I make the elevation 2.3 degrees from 500 km away, and marginally less than nothing from 712 km. -- © John Stockton, Surrey, UK.

Looks like only visible by seabirds off the launch boat.
It seems to have split! Hope they try again, Kevin www.kevsmith.com www.siriusobservatoriesuk.com DayStar Filters UK Lille Coronographs, telecentrics, and Herschel wedges.

Launch was due for today but was pushed back to tomorrow as tomorrows weather looks a little less cloudy (and thus less ice will form on the envelope - possibly dozens of tonnes of it !) I'm certainly taking my Bino's to work and hoping to catch sight of it mid to late morning Doug It'll be interesting – heard on the radio this AM that the launch has been put back to next year. This is due to a leak in the balloon (which is pretty much what Kevin said, I suppose ;-) -- Simon 51:31N 0:38W http://www.cookie-pool.co.uk/Pool1.htm http://www.maidenhead.astronomical.s...care4free.net/ http://www.popastro.com/home.htm |

Yes, I posted in the last thread about this "I would like to see it, but surely 25 miles up is no great height, an elevation of 30% would surely only give a visible track of about 100 miles." but made no impression; Im a long way from being expert, so perhaps someone will comment on likely visibility mike r |
