1. The Yohkoh experience H. S. Hudson (SPRC/UCB) (subbing for Freeland and Hurlburt) Solar-B Science Meeting 3 January 25, 2002

2. Items to discuss Data management Software development Participation Operations Reporting Quality and quantity of science

3. Data management Lockheed manages: - data reformatting - data archiving - data distribution - SXT day-to-day operations Reformatter was functioning prior to launch SXT is the only operations-intensive instrument Data distribution was confusing at first

4. Software issues Lockheed manages: - “shared software” IDL environment - auxiliary databases (eg GOES, GBO) This has been highly successful, but a bit creaky even for Yohkoh data volumes Not every instrument participated well in this effort

5. Participation Many groups around the world successfully participate in software development, even including instrument characterization and calibration Good example of a remote group is Wroclaw, from which we have had real contributions both to SXT and HXT

6. Operations ISAS has been the (… => a) center for SXT science operations and observations This has worked extremely well. It is good to have dedicated science staff close at hand to the operations. That way one gets people like Shine or Hudson involved. It requires considerable expatriate staffing. Yohkoh has no weekend uplinks or data access.

7. Reporting Many groups and individuals happily analyze data and write papers. Science “nuggets” also arose. The motivation was to provide interesting augmentations to the otherwise pretty boring operations meeings. Nuggets may evolve in 2002 towards HESSI...

8. Quality and quantity of science The “Team Bulletin Board” system for managing research was ineffective Good research is almost un-manageable Research styles differ strongly in different groups Being co-located at an operations center is quite helpful in encouraging communication
