AstroGrid aims within Solar System science

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

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
  000000 and will automatically convert to
  numeric value.
• Capability to zoom in on time axis, define
  subsets.
  
• Votable field needs to have unitiso-8601 or
  UCD starting with time

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.

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 unitiso-8601.

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.
