The one that those are chasing right now is going north not south!

That one was yesterday evening. It was a foil balloon with a light payload. It disappeared from the map after a while and the guy that launched it thinks the battery died.

The wind will be different tomorrow - NE from Newbury.

Can a pressure release valve not be created to prevent the balloon from exploding so soon?

Any pics from the launch yesterday Dave?

Yes, can be done. I don't know of anyone who's had success doing so, but in theory it'd work. Then you could put plenty of helium in to get a good ascent rate, then vent as it rises to prevent the burst. Eventually it'll go anyway as UV will start to eat it.

My launch is tomorrow; I didn't have anything to do with that one yesterday.

Sorry!

I did read you mentioned Sunday then it went straight out my head again .

Good luck for tomorrow. Looking like very favourable conditions.

Still got my box that I built with the idea of launching but never got round to buying the balloon and helium then sorting the paperwork out. Hectic times recently I'm afraid!

Let me know if you need a hand launching/chasing or any advice . Also check out www.ukhas.org, and the #highaltitude IRC channel which is where everyone hangs out.

Looks like the fun is about to begin....1.30am here now though, and time for bed...wondered if the launch would wait until after the F1 was finished

[Vieste]

It is at 186m so far.

Grand prix just finished

[jeevescat]

Do we know what time the off is?

[Vieste]

It is moving now.

Mmm, has it come down again, didn't go far.

[jeevescat]

Now we're off,

[Vieste]

Still moving and going higher.

[Mobsta]

100 metres a minute ascent rate, at 2.7km now. Heading out in a bit, long car drive will keep an eye on it.
100m per minute seems slow, that's only +6km altitude per hour... Dave, is that ascent rate what you expected?

[Mobsta]

Now ascending at 4.5m/s, @ 5km... It's looking good. I'd put a fiver on you breaking the 40km marker

[Mobsta]

5.3m/s @ 7.3km... Slowly accelerating.

[Mobsta]

5.5m/s @ 11km
