1. The COMESEP Space Weather Alert System Luciano Rodriguez on behalf of the COMESEP Consortium (European Commission FP7 Project 263252)

2. The COMESEP project COMESEP (COronal Mass Ejections and Solar Energetic Particles) is a three-year EU FP7 project that started in 2011. The project combines expertise on CMEs, SEPs and geomagnetic storms from 7 European teams (and 3 external): – Belgian Institute for Space Aeronomy (N. Crosby, project coordinator) – Royal Observatory of Belgium (L. Rodriguez) – Hvar Observatory (B. Vrsnak) – University of Central Lancashire (S. Dalla) – University of Graz (A. Veronig) – Technical University of Denmark (S. Vennerstrom) – National Observatory of Athens (O. Malandraki) – Udaipur Solar Observatory (N. Srivastava) – CCMC, NASA Goddard (M. Hesse) – George Mason University, NASA Goddard (D. Odstrcil)

5. The COMESEP alert system

6. COMESEP 1st level producers: CACTus It detects autonomously CMEs in image sequences from SOHO/LASCO. Information on CME speed, angular width and start time are used by the system.

7. COMESEP 1st level producers: Flaremail Automatic flare detection in GOES X-Ray data. Provides flare magnitude.

8. COMESEP 1 st level producers: Solar DEMON The Solar Dimming and EUV wave Monitor provides information on flare location, automatically and in real time using SDO/AIA data.

9. COMESEP 1st level producers : GLE alert New Ground Level Enhancements alerts are sent to the COMESEP system http://cosray.phys.uoa.gr/index.php/glealertplus

10. COMESEP consumers/producers : DBM The Drag-Based Model provides ICME Sun- Earth transit time. Inputs from CACTus.

11. COMESEP consumers/producers : CGFT Input 1: CME speed: 2500 km/s Distance from disc centre: 0.01 Rs CME width: halo Flare type: X flare Interaction level: high Output 1: CME speed: 400 km/s Distance from disc centre: 0.99 Rs CME width: non-halo Flare type: C flare Interaction level: low Input 2:Output 2: The CME Geomagnetic Forecast Tool (CGFT) provides a probability estimation of arrival and likely geo-effectiveness of a CME based on its solar parameters.

12. COMESEP consumers/producers : SEP forecast SEP probability and storm level are calculated based on a multi-dimensional analysis using the available information of the incoming producer alerts. Triggered by Flaremail. Inputs from CACtus, Solar DEMON, GLE alert.

13. COMESEP consumers/producers : Geomag24 Estimates of the risk level of geomagnetic storm occurrence for the next 24 hours. Inputs from CACTus, Solar DEMON, Flaremail, CGFT, DBM and from a solar wind module.

14. COMESEP alerts Gmag #1: Triggered by the CGFT tool when a CME is estimated to be geoeffective. Gmag #2: It will provide the geomagnetic storm risk for the next 24h. Output of Geomag24. SEP alert: Triggered by the SEP forecast tool, it provides an estimation for a radiation storm with proton energies >10 MeV and >60 MeV.
