Yutaka Uchida, 1934-2002

>From Takashi Sakurai <>
>01 Sep 2002

Yutaka Uchida, one of the leading figures of Japan's as well as world's solar and astrophysics community, passed away on August 17, 2002, at the age of 68. He was at his son's wedding ceremony, and made a closing speech and then collapsed. His unexpected death was from cerebral bleeding.

He spent most of his research career (1962-1994) at the University of Tokyo (at the Astronomy Department and at Tokyo Astronomical Observatory). After retirement from the University of Tokyo, he moved to the Physics Department, Science University of Tokyo, organizing a group of simulation studies of astrophysical plasmas. There he also continued studies of the sun using data from the Yohkoh satellite: he served as the project scientist of the Yohkoh mission since the beginning of the project (1986).

His research activities were quite broad, but perhaps the best known is his interpretation of the Moreton wave as an MHD fast mode shock wave propagating in the corona. This issue has revived recently with the discovery of EIT waves, and he was very happy about it.

We are all saddened by the loss of a great scientist. A more complete obituary will appear in Solar Physics.

Meeting Announcements

Exploring the X-Ray Universe

>From Louise K Harra <>
>29 Aug 2002

There will be a meeting held at the Mullard Space Science Laboratory (MSSL), University College London, from 5-7 August 2003 called 'Exploring the X-ray Universe.' This meeting will be held in honour of Prof. Len Culhane's 65th birthday. Information on the meeting can be obtained at;

Three NOAA Workshops on Future Space Missions

>From "Terry Onsager" <>
>30 Aug 2002

The NOAA Space Environment Center will be hosting three workshops to investigate the requirements for future measurements of the space environment. Two of the workshops will apply to the next generation of GOES Spacecraft (GOES R+) to be launched sometime after 2010. These workshops will focus on the solar EUV and energetic particle flux measurements. The third workshop will examine the requirements for solar wind measurements. This new proposed satellite program is called Geostorms and will be a follow on to the NOAA Real-time Solar Wind system on NASA's ACE program.

These workshops will be held in Boulder, Colorado on the following dates:

Additional workshop information is available at .

Note: The Web site for the Energetic Particles workshop includes a questionnaire that we encourage all those who are interested to submit, including those who can and those who cannot attend the workshop.

Call for Papers, AGU Meeting Special Session SA04

Extracting Power from Rivers of Data - Data Assimilation into Solar-Terrestrial Models
AGU 2002 Fall Meeting
Moscone Center
San Francisco, California
6-10 December 2002

A special session will be held at the fall AGU meeting on assimilating data into solar-terrestrial models. Speakers that have been invited to this session include: Robert W. Schunk, Tamas Gombosi, an individual from the meteorological data assimilation community, and Ernest Hildner. Contributions from modelers who are planning to utilize multiple data streams (especially to adjust model output during a model run), from observers who believe their measurements can be used synergistically with others', and from those who have experience with relevant techniques to assimilate data into models describing other environments are welcomed.

Session Description SA04:

As this decade unfolds, we are challenged to use effectively the ever increasing amounts and kinds of solar-terrestrial data now scheduled to become available. How will we incorporate these data into our models to develop deeper and more accurate understanding, description, and prediction of the comprehensive and unified solar-terrestrial environment from Sun to Earth? This session's presentations will address the merits and the technical and conceptual issues of utilizing sparse and incomplete (relative to a model's spatial and temporal mesh spacings) measurements of multiple types to initialize, constrain, validate, and modify-in-progress the solar-terrestrial models of the future. For instance, how does a model "simultaneously" utilize the information contained in contemporaneous and repeated images, radio observations, particle measurements, and in situ plasma and magnetic field observations in a "self-correcting" mode? The expectation is that models which can incorporate many kinds of measurements synergistically and interactively will be more accurate, and provide more insight, than models which use measured values only as initial conditions and as metrics for the success of the model output.

Abstracts should be submitted to AGU by 05 September 2002, 1400 UTC through the on-line abstract submission form. Detailed information regarding the Meeting and abstract submission can be found at .

Solar Artwork

>From Stephen Walton <>
>3 September 2002

Americans know that U-Haul rental trucks often have artwork on the side depicting various historic or scenic sites in the United States. While on my Labor Day vacation at the Grand Canyon, there was a U-Haul truck parked outside the lodge at which my family and I were staying. On the side of this particular truck was a large painting of a solar prominence, with the legend "NOAA Space Environment Center, Boulder, Colorado."

Quite a nice little advertisement for our field, I think.

I encourage SolarNews submissions to be made as LATEX markup. Specific instructions and a LATEX template for submissions can be found on the Web at . Submissions should be e-mailed to . Please try to keep meeting and workshop announcements to no more than one page (50 to 60 lines of typed text with 72 characters per line), with a Web address for further information. Should you not use LATEX, a descriptive "Subject:" in the e-mail line will help in my markup procedure; that is, "Postdoctoral Position, Lumbago University" is to be preferred to simply "Job Announcement."

SolarMail address changes should be made via the Web site at . You can make the change yourself provided your old e-mail address is still active. Enter your SolarMail alias and password at that location. If you do not have a password, a new one can be e-mailed automatically to your old address; then follow the instructions at the Web site. Otherwise, e-mail your new address to both editor and . Indicate if you wish your new address published in SolarNews.

Keep those cards and letters coming.
