Yeah, catching Exception seemed to mean it was calling emit() after having failed previously with a cancellation.
Emissions from 'catch' blocks are prohibited in order to avoid unspecified behaviour, 'Flow.catch' operator can be used instead.
For a more detailed explanation, please refer to Flow documentation., but then emission attempt of value 'IssPosition(latitude=40.6431, longitude=128.8029)' has been detected.

A port of the Glance ISS Map Widget.
Adds rotation, eventually plot the trajectory of the ISS on the Map. And occasionally move the map to center it again.
