Herculis lost the satellite tag on the 21. February 2016. Each harness is equiped with a weak point, which will open after some time. The weak point on the harness of Herculis opened earlier than we expected and hoped. Herculis was observed after the loss of the tag and is still flying in the Alps. It is still possible to identify Herculis with an observation of rings of gentically with a found feather.
