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.<div>

Rising very slowly. But it reached Freezing (0C) at 0020z so that should be<br>
about 7500'<br>

But We notice another Device with CW on nearly the same freq. Our dial freq<br>
will be 28.223 USB dial, but we hear another CW signal (Italian) down at<br>
28.222 USB dial.</B><br>
<P><br>
<br>
Filling balloons now.<br>

Balloon web page is up. Launch hopefully by sunset from Annapolis Maryland.<br>

If we are lucky, we hope to launch our 6 party-balloon long duration payload<br>
Thursday evening around sunset EST. It has no APRS, just a 10m CW<br>
telemetry system. We will have to locate it by signal strength and beam<br>
headings only.<br>
<br>
If you have APRS you can uplink your beam heading via APRS so we can see the<br>
DF solution maybe...<br>
<br>
More tomorrow (again, if we are lucky). It will only be at 15,000 feet or<br>
so, vulnerable to weather and not so great winds...<br>
<br>
The battery could last 10 days....<br>
