The ESA Space Weather team is pleased to announce that SWE Portal 3.16.0 was released on the 23 June 2026.
In this update, the ESA SWE Services have been enhanced with the incorporation of the following new and updated products and tools:

From the Solar Weather Expert Service Centre:
- Collecte Localisation Satellites (CNES/CLS) provides:
- The S.508b CLS F10.7 and F30 nowcast & forecast product visualization has been updated to improve y-axis scaling and readability, while preserving the F10.7 correction date markers.
From the Space Radiation Expert Service Centre:
- The Space Research Laboratory, Department of Physics and Astronomy, University of Turku (UTU/SRL) provides:
- An update to the catalogue R.166 "Very high-energy solar proton event database" (Version 1.1) to include 5-min spectra for two GLEs which were not available previously, GLE 65 (2003-10-28) and GLE 66 (2003-10-29). In addition, the flux spectra of GLE 59 and 70 were updated with new values based on a recently revised analysis utilising an updated Neutron Monitor yield function.
- An update to the catalogue R.130 "Solar Energetic Particle event catalogue: High-energy solar proton events" (Version 2.2) to include thirty-seven (37) new events bringing the catalogue up to date until 31/03/2024. Note that for this update ERNE data was used without the saturation correction (EPHIN) and for the high proton energies GOES SGPS data was used instead of SEPEM RDS.
- The Royal Belgium Institute for Space Aeronomy (BIRA-IASB) provides:
- A minor update (v1.1) to the ICEA interface group (R.178-180) which includes revision of the documentation, addition of explanations regarding the meaning of the colour codes together with how the risk is determined, more details regarding the VSWMC model chains, and an update of the references to GOES-16 to GOES-19 due to the change of primary satellite.
- A new product R.134a "SEPForecast", which provides alerts for the risk of solar energetic particles events following solar eruptions and is a reimplementation of SEPForecast as a stand-alone product that is currently part of R.134 "The COMESEP Alert System". The alerts include risk levels for solar proton events with two energy thresholds (>10 MeV and >60 MeV) and are made available by means of interactive figures, e-mail subscriptions, and archives which can be accessed through webpage or M2M access points.
From the Ionospheric Weather Expert Service Centre:
- The Ionospheric Group of the National Observatory of Athens (NOA) provides:
- I.144, I.145 and I.146 TechTIDE products are now upgraded, offering a clearer and more meaningful interpretation and understanding of the products themselves.
From the Geomagnetic Expert Service Centre:
- The German Research Centre for Geosciences (GFZ) provides:
- an update of the graphical output of the products providing nowcast of the following geomagnetic conditions indices Kp, Hp60 and Hp30. The graphs have been redesigned to display a continuous 7-day time series in a single unified plot.
- The Finnish Meteorological Institute (FMI) provides:
- An upgrade of the demonstration product Regional Auroral Activity Index, Finland to fully pledged product. The product replaces the aurora nowcast instance previously provided by the Aurora Forecast Service product (FMI) that is now a forecasting application only.
From the ESA Space Weather Office:
- The ROSIE radiotelescope in Bialków, Poland, provides data on F10.7 and F30 radio fluxes with high cadence (original sampled, second, hourly) and daily averaged data, along with high cadence (with original sampling and 1-second) spectrograms. These datasets are retrievable via HAPI. Information and instructions can be found on the ESA Space Weather Data dedicated webpage (ROSIE).
- An update to the ESA Programme System Requirements (SRD) and Product Specification (PSD) documents. This issue of the SRD addresses updates to the core services and has been prepared as an intermediate step in order to handle flow-down of requirements from the SWE Customer Requirements Document updated in 2023 and other identified product specific needs. The PSD update also includes flow-down of requirements from the CRD and takes into account requirements analysis work carried out in support of the Vigil mission development.
- NGRM is the second Space Weather instrument flying as part of ESA's Distributed Space Weather Sensor System (D3S). Latest data from the NGRM instrument onboard the Sentinel-6B spacecraft is now provided as part of the General Data Services. Access this via the SWE Data Browser or API and find out more about NGRM here.
Changes made to product APIs in this release:
- R.134a: SEPForecast is now made accessible through the product's REST API. See the products help page for more information.
- Due to the SSO migration some the API URLs of some of the applications have changed. A table giving an overview can be found here; in case you encounter an issue, please consult the relevant product website.
Your feedback is important! We kindly invite you to participate in a survey to tell us your thoughts on the new SWE Portal, all feedback is welcome and will help improve the SWE Portal and better tailor our services to your needs.
Our SSCC helpdesk are here to help and can be contacted by sending us an email (helpdesk.swe@esa.int) or by filling the SWE Portal support request form. A short user satisfaction survey is accessible at the bottom of our replies upon closure of your requests, we would be grateful if you could follow the link to provide feedback on our helpdesk response and help us to improve our service.
