PECASUS has started 24/7 operations of the space weather services for civil aviation on November 7th 2019.

After one year period of consolidation and implementation the ICAO service operations for space advisories started on November 7th at 00 UTC. The PECASUS consortium volunteered to take the first shift (November 7th – November 19th) as the On Duty Center. The consortium partners have worked intensively during last months in order to finalize their data product processing and dissemination routines to match with the quality requirements expected in aviation services. In addition, the propagation of space weather test advisories in the ICAO communication framework have been tested since late September by PECASUS and the two other space weather centers. Unless interrupted by real advisories, the dissemination tests will continue still during the operations phase in order to ensure their availability for all ICAO member countries.

The operational phase of ICAO space weather services was launched in calm solar activity conditions. No aggressive looking sunspots were visible on the solar disk and the solar wind showed its nominal behavior without any significant bursts or high speed streams. Such calm conditions are expected, because we are currently living the years of solar activity minimum. The activity is anticipated to increase during the coming years as the next sunspot maximum approaches. In the current forecasts the maximum will take place around 2024. However, it is good to recognize that in the past intensive solar storms have taken place also during solar activity minimum years. For that reason PECASUS wants to ensure that already from the very beginning of the ICAO service operation phase its expertise is available in its full capacity for enhanced safety in aviation against space weather risks.
