UTD DMSP SSIES Ion Obs Available on Web for Sep 1999 Space Weather Month
Sent Sep 24, 1999
As our contribution to the Space Weather Month Campaign, the Center for Space Sciences at the University of Texas is processing and placing on-line the thermal plasma data from the SSIES instrument packages on board the operational DMSP weather satellites for the entire month of September. The DMSP spacecraft fly in sun-synchronous polar orbits at approximately 800 km (topside F-layer) with an orbital period of about 105 minutes. We are processing data from the F12 and F13 satellites and the dataset includes in situ data from the satellite giving the ion flow (three components), ion density, ion composition, and the calculatedelectrostatic potential in the polar cap for F13, all at a four second resolution. A full explanation and links to the available data are given on our website at

UPDATE 9/15/99
Re: New URL for prediction of high latitude magnetic field perturbations
Near-real-time high-latitude magnetic field predictions are displayed at:
http://lepgst.gsfc.nasa.gov/people/vassi/rt/main.html
In a way similar to the magnetic indices, the field's spatial distribution is predicted from propagated solar wind data via a nonlinear dynamical spatiotemporal model. Derived electrojet indices and the location of theminimum (in latitude and longitude) as functions of time during the last hour are also displayed. The lead time is the same as in the magnetic index near-real-time prediction (see description above) while the time resolutionis 1 min. The display is updated once an hour.

NEAR-REAL-TIME PREDICTION OF THE SPATIAL STRUCTURE OF HIGH LATITUDE MAGNETIC FIELD PERTURBATIONS
-----------------------------------------------------------------------------------------------------------------------------------------------
As part of the September 1999 Space Weather Month Campaign, we have been working on putting a near-real-time prediction of the spatial structure of the high latitude magnetic perturbations (HLMP) on the web. We have a model prediction of the spatial structure of the HLMP and the related current system on the page
http://lepgst.gsfc.nasa.gov/nrt_predictions.html
This nonlinear model runs from ACE data, that we obtain in near-real-time, to predict the evolution of the HLMP. The evolution model is based on a mixture of phase space reconstruction and fuzzy logic pattern recognition. Also, the data has been balistically propagated to the subsolar point.

NEAR-REAL-TIME PREDICTIONS OF AL/AU
---------------------------------------------------------------------------------------------------------------------------------------------
Near-real-time AL/AU indices are made available at:
http://lepgst.gsfc.nasa.gov/people/vassi/rt/main.html
The indices are predicted from propagated ACE solar wind data via a nonlinear dynamical model. The total lead time is 0.5-1 hour propagation time to the subsolar magnetopause plus ~2 hours of projected solar wind. The time resolution is 2.5 min.
Daily predictions of the electrojet indices from ACE and from the Thule Polar Cap index can be found at:

Re: Summary of Campaign Support and Location of URL's for
POKER FLAT ALL-SKY CAMERA
The All Sky Camera at Poker Flat Research Range will run during the campaign. Last night the ASC ran with the lens cover on, but we plan to operate the ASC in normal mode for the rest of the week. The real time images (once a minute, during darkness) are available at http://www.pfrr.alaska.edu/~pfrr/DATA/ASC-COMB.HTM
A keogram type summary plot from the ASC (updated in real time as well) is at http://www.pfrr.alaska.edu/~pfrr/DATA/ASC-SUM.HTM and mpeg movies of the previous nights are at http://dac3.pfrr.alaska.edu/PFRR99-0/DATA/MPEG/ASC-PKR/. This link gives a directory listing with the date encoded in the filename, last night's movie (with the lens covered) for example is in file AS990914.MPG.

POLAR UVI CAMPAIGN ARCHIVES and NEAR REAL-TIME
The auroral images made with UVI are available on 10 minute resolution at http://uvisun.msfc.nasa.gov/data/1999/brwse.html. The browse images are updated as full 24 hr files become available. Currently, data through 9/6/99 is online. The gif files show the raw UVI data with continental outlines overlain and an MLT plot of the data above 50 degree magnetic lattitude. For more up-to-date near-realtime images telemetered during contacts with the spacecraft, see http://uvisun.msfc.nasa.gov/data/1999/nrt.html.

RE:
UPDATES ON DST PREDICTION
Below is an updated list of Dst prediction sites, using a variety of techniques, supported by campaign participants. These sites will be linked in to the SPARC real-time magnetic indices pages and can also be accessed from the participant list on the SRAMP campaign pages. If there are other sites of mutual interest, please email me with the URLs and I will make sure they are all linked in to the campaign pages.

SPARC SIGN-ON
The SPARC realtime screens will be up an running by tomorrow. You can access them from the SRAMP campaign pages by clicking on SPARC in the header or in the line of links buttons at the top of the screen. First you will encounter a SPARC registration and login page. You can either login as a guest or as a registered user. As a registered user you will have access to all of SPARC's capabilities. As a guest, you will be able to view any of the pages including the real-time data displays.
To register, simply click the register button, fill in a user ID and password of your own choosing along with your full name and email address. Registration is immediate. The main page includes a user's guide in case you would like to try out SPARC's capabilities for creating your own pages, entering comments in the chat box,etc. If there are problems, contact SPARC administrators or send me email and we will get them straightened out.
Now all we need is for the sun to cooperate and maintain or enhance the
current magnetic activity levels for the next leg of the campaign. As it
stands, the Sept 99 campaign has already achieved considerable success in
observing a large magnetic storm over the last several days. More to come?
An expected magnetic storm took place yesterday, it started at around 09UT and Dst reached its minimum at 11UT on Sept.12. Depth of Dst will be 150nT. Solar wind velocity is still increasing and some follw-up magnetic disturbances will be strongly expected. As shown in http://www.ips.oz.au/asfc/sramp.html, we have been expecting recurrent high speed stream should come on late Sept.12 or 13. Its arrival seems a little bit earlier...... I believe this major magnetic storm will be a good candidate in the Sapporo conference, we, therefore, timely announced it to enhance observations in our country....... With best regards, T Obara

Message from John Foster:
Solar active conditions have been experienced during the past week. This is the third consecutive appearance of this active region, with ~27-day recurrence period. This confirms and reinforces the selection of 15-17 Sep 99 as the final dates for the core of the WLS99 ISr World Day experiments which will also support SPARC and the Space Weather month activities. Average Ap index has exceeded 25 for the August activity and is building in intensity as equinox conditions approach.
Observatory status:
Coordination of ISR Observations
This will be a three-day (72-hr) World Day experiment. Millstone Hill will begin operations at or before 00 UT 15 Sep 99. Other facilities can adjust their start/end times to facilitate local conditions and to provide best coordinated coverage of active conditions.
Status & Alerts Information
Experiment status and alerts, etc will be distributed to this e-mail list.
Please inform John Foster of any changes or significant information.
