Introducing the SID Data Grabber

Thanks to a great volunteer effort by George Silvis, Sudden Ionospheric Disturbance (SID) observers can now use the SID Data Grabber help prepare an AAVSO SID report file from their Stanford/SARA superSID monitor log files. Please visit the SID Data Grabber page to read more and download this handy application.

SID Data Grabber

The SID Data Grabber is an application to help prepare an AAVSO SID report file from your Stanford/SARA superSID monitor log files. It offers a zoomable graphical view of the log data where you can click the graph to grab the times then puts them into the AAVSO format report file, ready for submission at the end of the month.

The Gyrator III VLF Receiver

The latest version of the Gyrator series of VLF receivers (first developed in the 1990s) is the Gyrator III, a revision of Arthur Stokes' Gyrator II by Guglielmo Di Filippo (observer A-93).


Circuit diagrams and wiring for the Gyrator III are available here in Microsoft Word and PDF formats: .doc, .pdf

The reduction process is quite simple, and consists of the steps which follow. First, the universal time for each of three event-phases must be measured for each SID. Examples are indicated on the recording at the end of this report.
