Circled by a HAB whilst sleeping.

It seems that the balloon, B-30, came to play last night whilst I was asleep.  I started tracking B-30 earlier in the evening and the signal was getting stronger as it moved eastwards towards me when I fell asleep.  It was quite surprising that I could still hear B-30's signal when I woke up this morning, but nowhere near as much of a surprise as when I realised that B-30 had flown right around me then changed to a northerly course.
