Below are links to a HYSPLIT 12-hour trajectory prediction based on the last estimated lat/long that I saw on APRS.fi at 0300 UTC and Bob's altitude estimate of 15,000 feet. The first link is to a PDF and the second is to a Google Earth KMZ.

This prediction puts the balloon over Bermuda at around 2100 UTC on 30 Mar 2012.

Balloon was released at 2330z (1930EDT) and is headed SE from Annapolis at 6 knots.
Rising very slowly. But it reached Freezing (0C) at 0020z so that should be about 7500'

But We notice another Device with CW on nearly the same freq. Our dial freq will be 28.223 USB dial, but we hear another CW signal (Italian) down at 28.222 USB dial.</B>
<P>
Filling balloons now.
-----Original Message----- Balloon web page is up. Launch hopefully by sunset from Annapolis Maryland.
Start here: http://aprs.org
-----Original Message----- If we are lucky, we hope to launch our 6 party-balloon long duration payload Thursday evening around sunset EST. It has no APRS, just a 10m CW telemetry system. We will have to locate it by signal strength and beam headings only.
If you have APRS you can uplink your beam heading via APRS so we can see the DF solution maybe...
More tomorrow (again, if we are lucky). It will only be at 15,000 feet or so, vulnerable to weather and not so great winds...
The battery could last 10 days....
