I’m hoping to send a flight across the Irish Sea to land in Northern Ireland. Launch time approx 10am this coming Thursday.

The wind conditions are unusual with the lower winds southerly and the upper winds easterly.  I will be aiming the balloon over towards Northern Ireland where Philip Heron will be waiting to chase it.  The flight profile is tricky with about 1.2m/s ascent rate. It may or may not achieve a float before the balloon is cut away at a longitude of -6.5.

Here’s the current prediction:
