***Reminder: Abstract submission deadline 1st September ***
For full details see: http://sidc.oma.be/esww5
The next European Space Weather Week will take place at the Royal Library
of Brussels, Belgium, from Monday 17th November to Friday 21st November
2008.
This meeting is being jointly organised by the Royal Observatory of
Belgium (ROB), ESA, the SWWT, the COST 724 and COST 296 communities.
The local organisation is done by the SIDC of the ROB. This event will
build on the advances made during previous European Space Weather Weeks
and preceding ESA Space Weather Applications Workshops.
The ESWW will again adopt the central aim of bringing together diverse
communities working on all elements of space weather with a strong focus
on user involvement. This year?s meeting will discuss recent advances
in both scientific and applications based domains and how these advances
relate to user needs. It will also provide an opportunity to discuss the
Space Weather community?s contribution to possible future ESA action in
the area of Space Situational Awareness. New data, tools and techniques
will also be discussed and demonstrated during the workshop with a view
to aiding the transition between new scientific results and user-oriented
space weather services.
This year?s event will include a space weather fair, where users and
service providers will have the opportunity to interact in an informal
working environment. The meeting will also include a number of hands-on
splinter sessions and will explore community development through several
dedicated business meetings.
Organisation:
The meeting will centre on 6 open sessions that address a number of topical
themes:
Session 1: Space Weather and the European Approach to Space
Situational Awareness Session 2: Global Navigation Satellite Systems :
Science, user needs and applications Session 3: Offshore Drilling,
Magnetic Surveying and Geomagnetism : Science, user needs and
applications
Session 4: Space Weather Models: from Research to Operations
Session 5: New and Existing Data Resources, Tools and Services Session
6: Solar Weather: New results, analysis techniques, forecast tools and
the outlook for users
Each session will be divided into oral and poster session with plenty of
time devoted to discussion. Contributed papers are welcome to each of the
6 sessions. The oral presentations will cover a range of scientific and
applications related themes and will consist of both invited and contributed
papers. User contributions are expected to feature strongly in sessions 2
and 3 in particular. It is also envisaged that the meeting will conclude
with a wrap-up of the key issues arising during the week long event in the
form of a round table discussion on future European directions in space
weather.
Business meetings:
A key part of the European Space Weather Weeks are the business meetings.
These meetings provide the opportunity for interested participants to meet
in smaller groups and address key issues in a style that compliments the open
format of the plenary sessions. These meetings take the form of working
meetings with reports produced and actions taken by the participants. This
year, time during the ESWW5 schedule will be set aside for all splinter
meeting
convenors to report the main conclusions of the meetings to the full workshop.
Topics that will be covered by splinter meetings during this year's ESWW
include:
Science Consortium for SWAP and LYRA payloads onboard PROBA2COST 295

4. Meeting: Modern Challenges in Nonlinear Plasma Physics
**********************************************************************
From: Dimitris Vassiliadis
MEETING: "Modern Challenges in Nonlinear Plasma Physics:
A conference honoring the career of K. Papadopoulos"
June 15-19, 2009, Sani Resort, Halkidiki, Greece
First Announcement
In the last three decades theoretical and experimental progress has led
to a substantial integration of nonlinear effects in modeling and
understanding of plasma dynamics. Particle acceleration mechanisms,
collisionless shocks, magnetic reconnection, and flow and wave
turbulence are only a few of the facets of complex dynamics in space or
laboratory plasmas. Moreover, the realistic behavior of plasmas in
geospace, solar, and fusion environments is modulated by strong
interactions with adjacent plasmas or boundaries. Large-scale coherence
emerges even in weakly-coupled, multi-scale plasmas. Accurate modeling
and prediction of nonlinear plasma systems has demanded development of
new theoretical and numerical methods. The meeting will review recent
key developments in these areas and help chart the exciting future of
nonlinear plasma science.

Hi Doug, all
this beacon looks good. COMPASS made no hard reset and all settings are valid.
Yesterday evening I heard the beacon and the temperature was 0? . So I
commanded the satellite to switch off the heater at 0 degr. It seems that has
worked. After this command I sent the treshold value to -50 degr.
Now we can see that the heater is still off (also at low temperatures). This
evening I will try to change the voltage treshold - maybe I can switch COMPASS
into powersafe mode. That means we can hear the beacon every 3 minutes.
Please stay tuned and listen to the beacon. Thank's a lot for all your
efforts.

Using the same S band converter that i was using with AO-40 i succeed to have
some QSO on AO-51 VE2NPC and another station but i am not
100% sure of his callsign.
First i think Squidly Diddly will be the type of operator best equipped to
handle my station in L/S mode on a LEO sat. I am using my PCR-
1000 to have a graphical display of my up converter output on the scope
display. Since my first attempt on L/S mode i found very hard to be
on the right uplink frequency. This morning pass i heard Clare VE3NPC
transmitting a couple of time to find the right uplink frequency on
my side even adjusting as per the Orbitron doppler corrected uplink i was
always out of the satellite L band receiver until i start to
adjust my TX frequency lower and higher than the program displayed frequency.
I ended up with a 15KC higher than the "supposed" doppler
corrected frequency on Orbitron?
Could be my upconverter is not properly aligned or the scope display on the
PCR-1000 software is not too exact at 1.268GHZ?
At the end i will have to set the satellite RX frequency 15KC up to be able to
get in the RX pass band.
Next step is to have my uplink frequency controlled by my PC as i need 2
additional arm here in the shack!
Bottom line L/S is feasable and with some tweeking it can probably matched the
V/S mode +- the obstacles and foliage blocking in the path.

Hi,
I want to try and use L/S mode on the different satellites but I am not
equipped for running this mode, I only have a VHF and UHF transciever.
For VHF a Kenwood TS-711e and for UHF a Kenwood TS-811e. I also have a
Kenwood TS-430s for HF.
What is the best place to look for information regarding L/S mode equipment?
And then a site or good book with information about radio equipment, but also
antenna information.
Hope to hear from you.

Hi all,
COMPASS is back in powersafe mode :-).
You should hear the beacon now every 3 minutes.

Now it?s very important to collect telemetry. If the voltage climb over 4
volt we can change to NORMAL mode.
********************************************************
PLEASE do NOT send any commands to COMPASS until further notice
********************************************************
If you send any commands you overwrite the current settings and COMPASS may
fall back into emergency mode.
I will keep you informed about the next steps.
For your information here are recent reports from today. Thank you very much
for your efforts.

It?s better to be prepared (SSTV on ISS)
It is better to be prepared for the arrival of new projects on ISS, rather
than being caught off guard for a project. In July 2006 the ARISS team was
caught off guard by Commander Pavel Vinogradov on board ISS when he called
Russian Mission control and informed them he was going to test Slow Scan TV
from ISS, via a borrowed laptop computer. Pavel wanted to use SSTV to
communicate with families and friends around the world during his ISS mission
during the summer of 2006
At ARISS we were not expecting SSTV for another year at least since we still
did not have an allocated laptop for Amateur Radio operations. We were also
missing one chapter in the SSTV manual, and that was the chapter explaining
which buttons to push on the D700 to take it out of cross-radio packet mode
and put it on a pair of channels for SSTV. After a few tries, Commander Pavel
Vinogradov was able to get the D700 into Simplex mode and we began to see a
hand full of SSTV images coming down from ISS for the first time.
http://www.marexmg.org/imagessstv/SpaceCamImages1.htm
Since Pavel had set the radio to the wrong frequency we did not push this
information out to the Amateur Radio public for political reasons. The down
link frequency was perfectly legal under ITU Laws, however it was not one of
the gentlemen?s agreement frequencies (ITU Laws, Satellite band 2-meters
uplink and downlink, 144.000 ? 146.000 MHz).
As a result of being unprepared, we missed a great opportunity to show the
world what we can do with Amateur Radio SSTV in space. To date we are only
aware of 8 unique images sent to Earth from ISS via Marex SpaceCam.
Two years later, we are still not prepared.
Astronaut tourist Richard Garriott?s is interested in using SSTV as part of
his mission. Assuming the big huge stack of papers is signed by a bazillion
people we may see some SSTV.
We still do not have a dedicated laptop.
We still do not have chapters for setting up the D700 (see side notes #1 on
the D700).
So while ARISS and the space agencies are busy shuffling papers, we should not
sit idly by and wait. We should be ready for the possibility of SSTV from ISS
during short Garriott?s mission in October 12-20th, 2008.
After all, for a 30 million US dollar space ride ticket, you do have some say
in what project you want to run while on board ISS.
So, Dust off your 2-meter station.
Download your favorite SSTV application.
Plug your computer into your 2-meter station and start experimenting
terrestrially with other friends on 2-meter FM SSTV.
As for Future Amateur Radio projects on ISS, you need to Tell ARISS/NASA what
types of projects you think would be beneficial to the Amateur Radio space
program.
Do you still want Packet?
Do you want a cross band repeater?
Do you want Streaming SSTV?
Do you want Streaming Web quality video?
Note: Fast scan TV will not fit in the satellite ITU band segments.
Data speeds over 1 megabit are not practical because of Doppler issues and the
cost of your radio station will be out of the reach of most of us.
ISS Available Resources:
We currently have 7 coax cables on ISS that are connected to real antennas on
the outside hull of ISS, which can be used for Amateur Radio projects.
Only one of these cables is currently connected to an amateur radio project
(Kenwood TM-D700) the rest of the cables are not currently being used and are
available for Amateur radio projects.
Cables 1-3 Multi-band antennas, 2-meters, 70cm and a patch 1.2-2.4 GHz (high
coax loss above 1.2 GHz)
Cable #4 10 meters receive only antenna (will need a spacewalk to attached
ground radial if you need to transmit on 10 meters)
Cable #5 2-meter antenna in FGB module (co-phased antennas tuned for 147
MHz)
Cables #6 1.2 GHz patch Columbus module (Note #2)
Cables #7 2.4 GHz patch Columbus module
D700 Sidebar #1:
The D700 on ISS is programmed with a unique and very complex configuration
that uses both receivers and transmitters in a cross radio configuration (not
cross band, cross radio). Both voice and packet modes are running for most
modes at the same time. The cross radio setup made it very difficult for the
crew to change channels manually, because you had to set transmit and receive
channels on each radio separately. This is way Commander Pavel had such
difficulty in finding a channel that would work with SSTV.
The cross-radio setup caused numerous problems and ARISS finally agreed to
develop a simpler software setup. The new settings have been tested on earth
and a subset of the changes was manually installed on the ISS D700. Once we
turned off cross-radio operations we noticed a significant improvement in ISS
packet performance.
As of this writing the full new software load for the ISS D700 has not been
scheduled.
Side Bar #2 Columbus module:
At the present time the two antennas on the Columbus module are earmarked for
Amateur Radio digital TV. Just need working hardware.
Sincerely
Miles Mann WF1F, former ARISS technical consultant.
