Monthly Progress Report


Period: 2000-09-01--09-30

Authors: Lars Eliasson and Peter Wintoft

1. Progress status

The hourly ACE particle and magnetometer data have been added to the database. The data extend from December 1997 to September 2000. The real-time updating has not been implemented yet.

The help pages for the data plotter and superposed epoch analysis tools have been updated.

An Inspect button has been added to the data plotter tool so that the user can get information about the data, such as start and end dates and a description of the data. If the user tries to load data for a time period that is not in the database then a dialog window will appear with an error message.

A Java code prototype model for the prediction of the GOES-08 >2 MeV electron flux has been created. The prototype includes all the steps from retrieving the data from the database, normalization, creating time delays, loading the neural network, running the network, and de-normalization of the output. The model will be set up for real-time operation using the hourly ACE data.

The database Java code has been updated to include several new functions. Firstly, there is a function for retrieving re-sampled data. This is useful when long time-series of data, with an originally high time resolution, should be loaded over the internet. Another function is the possibility to load just one data field from a database object. Again, this is to improve the internet performance. Finally, a function to retrieve only summary information such as the mean and standard deviation for the superposed epoch analysis tool has been implemented.

The last few days were used to prepare two posters for the S-RAMP conference in Japan, one on SAAPS and another on the GOES-08 electron flux prediction.


WP 110 URD for the database and database tools

An updated User Requirements Document for the database and database tools URD v ersion 1.1 of WP110 was delivered on 27 April 2000.

WP120 SRD for the database and database tools, DB&T

The SRD Version 1.0 was delivered on August 18 2000.

The technical note TN 1 (Database and database tools) version 0.2 was delivered on 31 January 2000. This note had previously the title Exploration of data.

WP130 Development of DB&T

The database is running including all data that appear in the URD except the low-orbit data.

Historic data set consists basically of the OMNI data. All real-time data are being stored and some data are transferred to the historic data set.

Five anomaly data sets are now included. Some smaller updates have been made. The beta version will be made available before asking for more data from operators.

WP140 Test and update of DB&T

A test plan will be written and sent to ESTEC for approval.

WP205 Prototype of Satellite Anomaly Analysis Module, SAAM

A description can be found at: http://www.irfl. lu.se/saaps/saapsint/wp205/wp205doc.html

WP210 URD for SAAM

The User Requirements Document for the Satellite Anomaly Analysis Module URD W P210 version 1.1 was delivered on 4 November 1999.

WP220 SRD for SAAM

The SRD Version 1.0 was delivered on August 18 2000.

An updated version of the technical note was delivered mid-March. An updated version of TN 2 (Satellite anomaly analysis module) version 0.2 was submitted 3 April 2000.

WP230 Development of SAAM

Data plotter routine and the superposed epoch analysis module are running.

More tools, such as entropy analysis, help functions and typical values will be implemented in the analysis module in the near future for beta release.

A password protected beta version of SAAM will be sent to ESTEC by 14 September and after approval made available to some of the operators.

WP240 Testing and demonstration of SAAM with new data

Start T0+17 according to the schedule

WP305 Prototype of Satellite Anomaly Prediction Module, SAPM

The prototype was installed on the server in April 1999.

WP310 URD for SAPM

The User Requirements Document URD W P310 draft version 1 was delivered on 17 November 1999.

WP320 SRD for SAP

The SRD Version 1.0 was delivered on August 18 2000.

The technical note TN 3 (Satellite anomaly prediction module) version 0.2 was delivered on 17 January 2000.

WP330 Development of SAPM

Anomaly sets will be analyzed with entropy methods to determine the most relevant parameters for each anomaly data set. Solar wind parameters (n, v, B), position, time, and magnetosphere data (GOES >0.6 MeV, > 2 MeV, Kp, Dst, LANL 10 keV and100 keV) will be tested.

A systematic study will first be done using one anomaly data set and be continued by training neutral networks and implemented on the web. Anomaly classes will be defined based on the outcome of the tests. The results will be presented in Technical Note 3.

WP340 Testing and demonstration of SAPM

Start T0+19 according to the schedule.

3. Peter Wintoft shall prepare a beta version of the SAAM for release and submit it to ESTEC by 14 September.

4. Peter Wintoft shall take contact again with Paolo Moldari (ESOC) and ask them to clarify what was meant by "official channel" before the end of September.

5. Peter Wintoft shall put the SRD version 1.0 on the web by 17 August. ** The SRD Version 1.0 has been sent to Alain Hilgers on August 18.**

6. Alain Hilgers shall comment or approve the SRD before the end of August.

7. Peter Wintoft shall write a test plan and send it to ESTEC for approval before the end of August. **A test plan for SAAPS is under development**
