Solar Event Catalogue

This page describes how to access the Solar Event Catalogue via Astrogrid.

The Solar Event Catalogue, developed by EGSO, can be queried from the AstroGrid VODesktop. Below are two examples of how to do this, and explore the results of the query using Topcat.

In VOExplorer, double click on Examples and choose the Solar Services list. In the list displayed in the right hand panel, select Datacenter for Solar Event Catalogue. Now choose Build ADQL to view the available catalogues and query them.

The drop down box next to Table allows you to view the catalogues part of the SEC and their columns. See screenshot. You can query on any column.

Example: Obtaining a list of solar x-ray flares with magnitude M1.0 or above, for times after January 1, 2003

The ADQL query that you need to send is:

    Select * From goes_xray_flare as t1 where t1.time_start > '2003-01-01T00:00:00' 
    and t1.xray_class >= 'M1.0'

Type in the query into the Edit box (highlighted in red in the screenshot below).

Click on Validate Edit: this will check that the syntax of your query is correct and, if not, will give you diagnostic messages in the Diagnostics box.

Click on the Execute. Messages related to the execution of this query will appear.

When the query completes, you will see the result file appearing under the messages. Click on its name (Result.txt in the screenshot). On the Top menu choose Result then Attempt to send tables to Topcat.
