EISCAT Facility Status

Tromsø VHF Radar

Last update: 2025-02-04
Status: OK. Cooling system is fixed, but it turns out 5 of 8 radiators have limited or no flow, meaning cooling isn’t at full capacity. This might cause problems when running both radars or on hot days. The problem will be investigated as soon as schedules allow.
