1.Special issue of Annales Geophysicae devoted to the science of Space 
   Weather
*****************************************************************
From: Mike Hapgood 

1. During the Space Weather session at this year's European Geophysical
Society meeting, there was a proposal to have a special issue of the EGS
journal, Annales Geophysicae, dedicated to the science of space weather.
This special issue could host papers from the EGS meeting but would also 
be open to wider contributions. It would not be considered as proceeding
of the session but would instead be a collection of standard reviewed
papers - as appropriate for Annales.

2. The proposed deadline for submission is September 2001 with the aim
of publishing the special issue in May or June 2002. Submissions received 
after the deadline would still be accepted but would be unlikely to be 
included in the special issue. For more information on Annales Geophysicae 
and its publication policies, please see the Annales web site
(http://www.cesr.fr/~anngeo/). Please note, in particular, that Annales
does not charge for publication of colour or greyscale figures.

3. Submission can be electronic via e-mail attached documents, or by 
post, but electronic submission must be followed by a paper copy sent 
by post to the Annales Office. See the Annales Instruction to Authors
(http://www.cesr.fr/~anngeo/HowToSubmit.html) for more details. All
correspondence concerning this special Issue should be addressed by 
e-mail to the Office, with "Space Weather" in the 
"subject area".

4. Mike Hapgood has agreed to act as Guest Editor for the special 
issue. He will help the Annales Editorial Team
(http://www.cesr.fr/~anngeo/Editorial_Office.html) in referee finding, 
paper evaluation and editorial decisions.

5. If you are interested to contribute a paper for possible publication
in the special issue, please contact Mike Hapgood .

2. Report on NOAA Space Weather Week
*****************************************************************
From: Barbara Poppe 

Space Weather Week May 1-4

Space Weather Week concluded on a high note. The final talks were at
least as good as the rest of the weeks's. We learned about the problems
with radiation hazards to Canadian satellites and to the Internaational 
Space Station. From a physician's viewpoint, we learned about the 
career-ending exposure that astronauts get in one or two missions. 
Research advances that can help mitigate these problems were discussed 
in the context of user concerns.

Such was the tone of the week, as we looked at ionospheric disturbances
causing serious communications problems for aviation, GPS errors of up 
to 45 vertical feet, atmospheric drag that is monitored for changes in 
orbits that are tracked to the centimeter, and geomagnetically induced 
currents that play havoc with power grids, even when they don't lead to 
catastrophic failure.

The 216 registered attendees conducted ad hoc discussions at every break
and social time, and the excitement was obvious. The sun should be given 
its due: recent high activity was a reminder that the space environment 
is a force to be reckoned with.  More complete summaries will appear on 
the web in the next few weeks (under Space Weather Week at sec.noaa.gov)

3. Report from Institute of Solar-Terrestrial Physics, Irkutsk (ISTP SD RAS)
*****************************************************************
From: Edvard L. Afraimovic 

1. During many years now, my group at Institute of Solar-Terrestrial
Physics, Siberian Department of Russian Academy of Sciences (ISTP SDRAS),
Irkutsk, has been engaged with research into ionospheric irregularities
and their effects on radio wave propagation, including the transionospheric
propagation of radio signals from geostationary and navigation satellites
(ETS-2 and GPS). Please have attached the list of our publications in 
refereed journals, as well as the list of E-prints.
 

2. Making use of the international ground-based network of two-frequency 
receivers of the GPS navigation system with a total number of no less 
than 800 as of February 2001, the data from which are made available via 
the Internet, has opened a new era in the field of a global, continuous 
and fully computerized monitoring of ionospheric disturbances of both 
natural and technogenic origins as an ingredient of the SPACE WEATHER 
complex in the geospace. In the very near future this system will be 
complemented through the use of signals from a similar Russian system,
GLONASS.

The ISTP SD RAS developed methods and a technology of a global GPS 
detector (GLOBDET) of ionospheric disturbances whose high sensitivity
makes it possible to analyze ionospheric disturbances with amplitudes 
as high as 10**(-3) of the background value of total electron content.
Compared to classical radio probing tools for the ionosphere, this 
technology is the first to ensure real continuous and global coverage
provided by a monitoring of ionospheric disturbances. The application 
of the new technology in investigations of geomagnetic disturbances, 
solar flares, earthquakes, ionospheric responses to rocket launches,
etc. is exemplified.
 

The use of the GLOBDET technology in the ISTP.

A. Observation of large-scale traveling ionospheric disturbances
(LSTIDs) of auroral origin by global GPS networks.

B. Geomagnetic and LT control of the spectrum of traveling
ionospheric disturbances based on data from a global GPS network.

C. Instantaneous response of the ionosphere to a sudden commencement
of the strong magnetic storms.

D. GPS global detection of the ionospheric response to solar flares.

E. The use of GPS arrays in detecting the ionospheric response
during rocket launchings, earthquakes and industrial explosions.

F. Ionospheric effects of the solar eclipses of March 9, 1997,
and of the August 11, 1999 as deduced from the GPS data.
 

3. My group has recently been engaged, in addition to developing 
detection techniques for ionospheric disturbances of natural and
artificial origins, with a study on the influence of geomagnetic
disturbances on the operation quality of the GPS receivers, which are
used in Global GPS network.

First results on the detection of this effect were reported on 
September 2000, in a preprint:

E. L. Afraimovich, O. S. Lesyuta, I.I Ushakov. Magnetospheric
disturbances, and the GPS operation.
LANL e-print archive. http://xxx.lanl.gov/abs/physics/0009027.

Abstract of this article:

"We have investigated a dependence of the relative density of phase 
slips in the GPS navigation system on the disturbance level of the
Earth's magnetosphere. The study is based on using Internet-available 
selected data from the global GPS network, with the simultaneously 
handled number of receiving stations ranging from 160 to 323. 
The analysis used four days from the period 1999--2000, with the 
values of the geomagnetic field disturbance index $Dst$ from 
0 to -300 nT. During strong magnetic storms, the relative density 
of phase slips on mid latitudes exceeds the one for magnetically quiet
days by one-two orders of magnitude as a minimum, and reaches a few 
percent of the total density of observations. Furthermore, the level 
of phase slips for the GPS satellites located on the sunward side of 
the Earth was by a factor of 5-10 larger compared with the opposite 
side of the Earth. The high positive correlation of an increase in 
the density of phase slips and the intensity of ionospheric 
irregularities during geomagnetic disturbances as detected in this 
study points to the fact that the increase is slips is caused by the 
scattering of the GPS signal from ionospheric irregularities".

4. We would like to propose the collaboration on:

-Investigation of the influence of helio-geomagnetic disturbances
of the geospace on the positioning accuracy in the GPS-GLONASS 
navigation systems, as well as developing algorithms and an automated 
software complex for monitoring and predicting the potential 
positioning accuracy, on the basis of analyzing real-time data from 
the global GPS system, and helio-geophysical data available through
the Internet.

- Investigation of ionospheric disturbances of a natural
(solar eclipses, flares, earthquakes, volcanoes, severe thunderstorms, 
auroral heating) and a technogenic origin (space-vehicle launchings,
industrial explosions, underground nuclear testing, etc.) as a basis 
for the development of a global radio system designed for detecting 
and locating these disturbances by processing the data from a worldwide
network of two-frequency receivers of GPS-GLONASS navigation systems.
