Real-time SANAE Geomagnetic Data

Sunday, September 7th, 2008

The Hermanus Magnetic Observatory, one of the institutions with on-going research projects here at SANAE IV, has recently been made the (ISES) Regional Warning Centre for Africa.  As part of this initiative, the magnetic data collected here (and at other sites) is available online in real time via their web-page,  By using the drop-down lists (see picture above) you can select for the SANAE data, which is updated every 5 minutes.  A large and sharp drop in the magnetic field is usually accompanied by an aurora.  In the graph below, you can see that there was a drop of almost 300 nanoTesla in the total magnetic field last night, just after midnight.  This is the typical time, as we swing furtherest from the sun and the ‘tail’ of the planet’s magnetic field passes overhead.

July SANAE Newsletter Online

Friday, August 22nd, 2008

It’s a little late but worth waiting for – the July Newsletter from SANAE 47.  This is the first time I’ve had to exclude articles to keep the length under 20 pages, and so I’m sure you’ll find that the content is fantastic.  There are some great pictures and personal stories as well.  Hot off the press – download it here or from the SANAE Newsletters page (link on right).
