1.  Cluster data on line 
***************************************************************** 
From: Philippe Escoubet 

We are happy to announce that the first data from the Cluster mission 
are accessible on line. 

The Cluster Science Data System (CSDS) is an integral part of ESA's 
Cluster Mission to the Earth's magnetosphere. You can access CSDS at: 

http://sci2.estec.esa.nl/cluster/csds/csds.html

To fulfil the requirement of exchange of Cluster data among scientists, 
the Cluster Science Working Team together with the Cluster Project have 
established CSDS, a distributed set of data centres, most of which are 
associated with one or more of the Cluster experiments.  With software 
provided by the experiment teams, each data centre processes the data 
for "its" experiments, and then exchanges it with all the other centres 
so that each centre obtains a full set in a standard format. 

Data sets provided are: 

Quicklook plots (CSDSWeb): 
     latest data from one spacecraft, including particle and wave 
     spectrograms, as gif files these data are available to the general 
     public. 

Summary Parameter Data Base (SPDB): 
     different parameters, from one spacecraft and averaged over one 
     minute, plus spacecraft position, separation distances, and spin 
     axis orientations; these data are available to the general public. 

Summary Parameter Plots: 
     plots of a subset of the Summary Parameters, one minute resolution, 
     6 hours per page, 4 pages for all parameters; i.e. 16 pages per 
     day; these data are available to the general public. 

Prime Parameter Data Base (PPDB): 
     parameters from all four spacecraft averaged over one spin period 
     (4 sec.); these data are restricted to the Cluster PIs and Co-Is. 

The PPDB and SPDB parameters are in physical units, and have been 
validated by the PI teams. During this validation process caveats have 
been added, concerning the limitations of these data, and the users are 
strongly encouraged to read these caveats prior to any study.

2. 3-d monitoring of the solar magnetic field 
***************************************************************** 
From: G.Ya.Smolkov 
George Rudenko 
3-d monitoring of the solar magnetic field 

I have the pleasure of bringing to the solar community's notice a Bd- 
monitoring system which generates, using data of Kitt Peak magnetograms, 
maps of the daily radial magnetic component at the photosphere, and 
daily coefficients of spherical harmonic expansion of the magnetic field 
within the potential-field approximation. Obtaining these data  is built 
upon a new technology for reconstructing the magnetic field from full- 
disk magnetograms [G.V.Rudenko, Extrapolation of the solar magnetic field 
within the potential-field approximation from full-disk magnetograms: 
2001, Solar Phys., 198, 5]. The data make it possible to carry out a 
detailed analysis of the 3-D magnetic structure and of its diurnal dynamics 
over a wide range of scales and heights above the entire visible surface, 
from structures of small magnetic regions to structures of large-scale 
global magnetic field at the source heights. The placing of the data 
archive and its updating and renewal every day is secured by the operation 
of the website  http://bdm.iszf.irk.ru. maintained by the Institute of 
Solar-Terrestrial Physics, Irkutsk, Russia. Posted on the website are the 
texts of programs for reading coefficient files and for calculating, based 
on them, the full magnetic field vector at any point. Furthermore, the 
website offers some of standard calculations of magnetic fields: small- 
scale and medium-scale maps of the photospheric magnetic field, maps of 
the radial component on the source surface, and calculations of open 
magnetic field regions. 

This result attract the attention and very useful for solar and 
heliospherical investigations in Space weather problems. 
Best regards, 
G.Ya.Smolkov

3. Updates of SPENVIS 
***************************************************************** 
From: Daniel Heynderickx 

Enclosed is a description of the latest updates to SPENVIS. This 
information, together with previous updates, can also be consulted at 
http://www.spenvis.oma.be/spenvis/updates.html

Sincerely, 

D. Heynderickx 
SPENVIS Project Manager 
 

- implementation of the following trapped radiation models: the AFRL 
  models CRRESPRO and CRRESELE, a low altitude proton model based on 
  SAMPEX/PET data developed by BIRA/IASB, and an update of the AE-8 
  model developed by A.L. Vampola: please consult the 
  http://www.spenvis.oma.be/spenvis/help/background/traprad/traprad.html
  help page on trapped radiation models before applying these models! 
  A full description of the models will be added soon. 

- implementation of combined runs for the radiation analysis, i.e. 
  selection of multiple models that can be run in one request 

- The PNG and TIFF formats have been added to all remaining output pages. 

- New tools or upgrades currently under development: 
   + development of a utility to fold dose curves produced by SHIELDOSE, 
     SHIELDOSE-2 and the NIEL damage model with the shielding distribution 
     produced by the sectoring tool: this tool is now in the test phase 
   + improvements to the surface distribution algorithm in the sectoring 
     tool: under development
