Scientific paper

The SIDC-Brussels, as WDC for the sunspot index and European RWC of the ISES, is the European hub for solar data and forecasts. Its services and products, while long established and widely recognised and used, are continuously being enhanced and supplemented. We present in detail the current status and outline the imminent improvements and additions. The Solar Weather Browser (SWB) is a free, downloadable, multi-platform visualisation package for real-time browsing of processed solar images from a variety of space and ground based sources, combined with context information (events, regions IDs, etc.) via a wide choice of overlay combinations. The Estimated International Sunspot Number (EISN) has been produced and distributed daily since January 2006 by the SIDC. Intended to support operational model predictions of ionospheric radio propagation, we present some early statistical results. CACTus, the operational Computer-Aided CME Tracking algorithm, now freely available to the community via the SSW software framework, is being tested for its real-time application to the STEREO/SECCHI COR-2 "space weather beacon" coronagraph telemetry stream. Also NEMO, a software package for the automated detection and morphological analysis of EIT waves presently being tested, details the relation between coronal EUV wave fronts and dimmings and characterizes their evolution; we present sample results of both developments. The Velociraptor software processes and interprets movies of the EUV solar corona, an algorithm identifying outstanding motions such as loop openings that are associated to space weather events. Sample results using EIT and TRACE data will be shown. A new flare catalog called B2X is presented, compliled via a method to detect automatically, and characterise according to time, localization, size, EUV flares belonging to classes B to X anywhere on the solar disc and at the limb. In addition we present a summary of the full range of products available from SIDC which can be chosen in any combination tailored to the individual, or group's needs. All products are available via the revamped SIDC website, http://www.sidc.be
