  1. Australian contribution to ILWS - 2008 Phil Wilkinson, IPS Radio and Space Services, Bureau of Meteorology Sydney

  2. Summary of Australian Interests • Space weather • service delivery • monitoring in real-time (IPSnet, WDC) • Realistic models • ionosphere • solar wind interaction • magnetosphere • Solar • Solar reconnection, CME and flare emission • Recognition of imminent solar activity • Solar magnetic structures

  3. Australian Contributions • Solar • Magnetospheric • Ionospheric • Space weather prediction • Southern hemisphere sites for satellite data downloads or ground-based monitoring • Solar Terrestrial and Space Physics website: http://www.ips.gov.au/IPSHosted/STSP/ • For further Australian sites

  4. Some Australian Space Instruments Antarctica FedSat – only spacecraft Oblique ionograms Culgoora Spectrograph TIGER radar Meteors

  5. Space Science Decadal Plan 2008-2016 • Themes • New Australian Instruments and Space Missions • Sun to Ground Science • Plasma to Planets • Remote Sensing Planetary Environments • Life in Space • Theory, Modelling & Data Provision/Storage • Progress • Round table meetings • Drafting, reviewing and reality checks

  6. Australian Space Weather Plan • Space weather monitoring & services • Become part of Bureau of Meteorology (May 2008) • Space weather research priorities • Research community agree priorities • Engage in University / Space Agency research • Community outreach • Education and enhancement of infrastructure design and planning

  7. FedSat Coordinates +X +Z X – azimuthal (East-West) Z – radial (outwards) Earth +Y(along track) Fedsat – An Australian Research Satellite (deceased) • Australia’s first satellite in 35 years • Built by Cooperative Research Centre for Satellite Systems (CRCSS) • 58kg micro satellite (approx 50cm cube), three-axis stabilised and with 2.5m deployable boom • Scientific and communications experiments • Launched by NASDA in H-IIA rocket in December 2002 • In a low Earth circular polar orbit, sun synchronous at 10:30 LT, an inclination of 98.7º and a period of ~101 min Above: Launch of the NASDA H-IIA rocket carrying Fedsat into orbit, 14 December, 2002. • Newmag magnetometer payload • Triaxial fluxgate magnetometer • Built in collaboration with IGPP/UCLA • Mounted on 2.5m boom to minimise interference from the spacecraft platform and other payloads • Burst mode sampling rate of 100 vector samples/second (nominally 10VS/s) • Quicklook data http://www.ips.gov.au/World_Data_Centre/1/5

  8. Newmag – 100Hztriaxial fluxgate magnetometer Fedsat South polar pass0320 - 0535 UT 15 October 2003 sun

  9. TIGER Tasmania TIGER New Zealand Geomagnetic Pole Geographic Pole TIGER: Tasman International Geospace Environment Radar TIGER : http://www.tiger.latrobe.edu.au/ • Concept: • 2 radars • with intersecting beams. • Advantages: • Lower latitude coverage than other SuperDARN radars • Provides essential longitude coverage for mapping convection in Southern Hemisphere

  10. Cosmic Ray Program Equipment • Multi-directional surface and underground muon telescopes (Mawson, 73 S mag and Hobart, 51.6o S mag) • Collaborative array with Japan, Brazil, Germany monitoring space environment variations Scientific Program • Magnetic storm precursor identification • CME shock strength and geometry via collaborating high and low energy monitor arrays

  11. Australian Monitoring network • Network of sites • Australian mainland • Antarctic Territory • PNG and Pacific Norfolk Is., Niue, and soon Cocos Is. • New Zealand • Low-High latitudes • 150E & 120E long. chains • Area covered • (110E-170W, 0-70S geog.)

  12. IPS Space Weather Status Panel

  13. Earth Station Downlink Availability • Aust. Remote Sensing Centre (ACRES) Alice Springs (9m X/S-, 5m X-band dishes) • TERSS (9m X-band Landsat 7) Hobart • Note: not verified recently.

  14. Radio astronomy ASKAP: Australian SKA Pathfinder http://www.atnf.csiro.au/projects/askap/science.html ASKAP is designed as a survey instrument: • 700-1800 MHz, • field of view of 30 square degrees, • cover the sky ten times faster than any current telescope. Primarily an astronomy instrument . MWA: Murchison Wide-field Array http://www.haystack.mit.edu/ast/arrays/mwa/ MWA is: • an array of 500 tiles • Operating frequency range of 80 to 300 MHz • An astronomical instrument with a solar component - SHI. SHI = Solar-Heliospheric-Ionospheric Science • Interplanetary Scintillation • Solar Burst Imaging • Ionospheric Structure

  15. WDC for Solar-Terrestrial Science • Solar data (real-time radio spectrograph, optical patrol images) • Ionospheric data (real-time VI ionosonde data) • Ground geomagnetic data (real-time variometer) • Magnetospheric (Fedsat) 3-component magnetometer • All-sky riometer • Imaging riometer • Cosmic ray data • Friendly displays

  16. Scientific Programs • Ionospheric prediction • Magnetospheric modelling • Polar/Auroral current modelling • CME and solar flare prediction • Propagation through interplanetary space • Far side solar holography • Data fusion recognition of solar active regions
