  • 16 October 07 IPS staff will be installing new equipment in the Culgoora solar observatory chamber over the next several days. There will be several short and some long interruptions to data streams from Culgoora over this period.    


  • 05 September 07 IPS is running an ACE satellite data driven model of the solar wind each day in the Australian Space Forecast Centre. The model output displays a complete solar rotation of several solar wind parameters, over the last 27 days. You can see the plot link and descriptive text at the bottom of the IPS Solar Wind Speed page, or you can directly view the plot produced by the model. Using 27 day persistance, which is the average solar rotation period. IPS forecasters can use this information to anticipate the arrival of a coronal hole high speed stream, and warn its customers of the expected disturbance.    

  • 04 June 07 Sunspot region 960 has been highly active since its appearance on 1st June, emitting 7 large M-class X-ray flares in 3 days. The region is magnetically highly complex and is growing every day making further flare activity and short-wave fadeouts very likely. So far the flares have been 'impulsive' or very short duration making mass ejections and proton events unlikely. Follow the progress of this region via the IPS Solar Summary and Solar Region Data.


  • 03 May 07 A large surge on the solar disk within sunspot region 953 was captured this morning at the IPS Culgoora Solar Observatory. While the associated flare was relatively small in terms of X-ray emissions (C9), H-alpha movies of the chromospere during the flare reveal rich dynamics in the underlying plage structure. See Movie.    


  • 14 March 07 Learmonth Observatory has re-opened following the recent shutdown due to cyclone Jacob.    


  • 08 February 07 A digital camera on the optical telescope (Razdow) was found to have failed. To quickly restore H-Alpha patrol the white light camera is now being used for the H-alpha data stream. This means that white light imagery will not be avaialable from the observatory until the faulty camera is fixed or replaced.    Culgoora optical observations Halpha back on line


  • 26 January 07 Culgoora Observatory equipment problems - no optical solar patrol. A fault in telescope electronics is currently preventing solar patrol. The earliest this fault can be fixed is early February. Radio solar spectrograph observations are not affected by this problem.    


  • 20 December 06 IPS media release and sequence of events for the recent solar activity. An exceptional month of unseasonally high levels of solar activity has come to an end with sunspot region 930 declining and moving to the far-side of the sun.
