White Star plans to launch a transatlantic balloon flight attempt at 0000 UTC (Thursday evening for most of the US). If you’re a ham operator set up for digital modes, you can monitor the telemetry transmissions on the 40m band and automatically report them. The flights predictions call for a three day flight.

Here’s the White star site

Here’s a link to their HF radio info page

Telemetry data is received and reported using the dl-fldigi application. The project page for that is here, but if you’re running Ubuntu Linux, just grab it from this ppa.

During the flight, you’re likely to find other people who are following the action in the #highaltitude chat on freenode IRC.

Also if you’re a ham using Ubuntu, check out the Ubuntu-hams team, or drop into the #ubuntu-hams chat on freenode IRC.

It can be a lot of fun to help track the balloon flights. Here’s a previous post I made about a tracking adventure.
