Karl Florian Goebel (18 October 1972 — 10 September 2008) was a German astrophysicist attached to the Max Planck Institute for Physics in Munich.

He had also been a member of DESY, a German-based research center that develops and runs several particle accelerators and detectors, most notably the ZEUS project.

His death led to the suspension of the official inauguration date for MAGIC-II, originally set for 19 September 2008.

Goebel completed his PhD in Physics at the DESY in Hamburg in September 2001 as part of his work on the ZEUS project.

[7][3] MAGIC-II, the companion to the MAGIC (Major Atmospheric Gamma-ray Imaging Cherenkov) telescope, is situated 85 metres from its counterpart at the Roque de los Muchachos Observatory on La Palma, one of the Canary Islands.
