At http://wattsupwiththat.com there are two more separate pages added to the blog. Go to top of Menu bar and click on Reference Pages and a drop down menu list appears. Click on Geomagnetic and this will take you to the new feature. At the bottom of the drop down list you can also click on solar – which is designed to accommodate postings on the subject of the Sun. Useful list of links on both pages.
