1. Solar and STP with AstroGrid Silvia Dalla School of Physics & Astronomy, University of Manchester A PPARC funded project

2. AstroGrid aims within Solar System science 1.Facilitate data retrieval and analysis across traditional Solar System ‘boundaries’ (e.g. solar / heliospheric / magnetospheric / ionospheric) → HelioScope. 2.Provide a framework for making models and applications available to the community. Feed real data as input to models. 3.Make available easy-to-use science services. Eg: Solar Movie Maker and CTIP model. 4.Facilitate multi-instrument, large dataset work. Time Cross Matching tool.

3. HelioScope First version of HelioScope working: VSO data + CDAW Solar image visualisation with Aladin

4. Topcat time-series Stackplot capability added Topcat will identify a time field containing ISO8601 time strings, eg ‘2002-07-28 00:00:00’ and will automatically convert to numeric value. Capability to zoom in on time axis, define subsets. Votable field needs to have unit=‘iso-8601’ or UCD starting with ‘time’

5. Solar System community and AstroGrid Positive reactions to HelioScope demos at MIST/UKSP meeting (April 2006). Several people are running the CTIP model using AstroGrid. Interest in using AstroGrid to identify times of multi- instrument high cadence coverage of the Sun. Time-series visualisation with Topcat also well received.

6. Current developments Ionospheric radar dataset (SuperDarn) at Leicester being linked up. This data will be passed as input to a new version of the CTIP model. Birmingham helioseismology dataset (Bison) Magnetometer data from Lancaster (SAMNET) Using Topcat time series capabilities: multi-instrument studies involving these datasets and RAL UKSSDC

7. IVOA update Generally, interest was shown in making sure that solar system requirements for standards are taken into account. STAP (Simple Time-range Access Protocol) presented. Key issue is take up of this (or similar) protocol within the Solar System community. Time UCDs – need for a better range of UCD words for time has been passed on and a new proposal for time branch will be circulated. A standard way to identify string time fields in Votables was agreed – this will be done by specifying: unit=‘iso-8601’.

8. Future work Improvements to HelioScope, especially links to more datasets. (eg Madrigal archive) Promoting STAP within Solar System community. New solar missions: Solar-B (MSSL instrument: EIS) and STEREO (RAL instrument: HI). UK archives for entire datasets are planned (MSSL and RAL): work has started to make data available via AstroGrid. Key solar datasets for cycle 4. Also for STEREO: models running on AG. STEREO
