Sailing on the Solar Wind

Guest Post by Willis Eschenbach The lack of cycles in the solar wind isn’t surprising when you analyze this paper. There is very little sign of any kind of annual cycle, which makes perfect sense because the sun doesn’t run by earthly clocks … the sun doesn’t know much about “one year for earthlings”. About…

New paper: Clouds blown by the solar wind

This paper suggests a terrestrial impact on cloud cover from the interplanetary electric field (IEF) via the global electric circuit. A primer video on the GEC is below. Clouds blown by the solar wind M Voiculescu et al 2013 Environ. Res. Lett. 8 045032 doi:10.1088/1748-9326/8/4/045032 Abstract In this letter we investigate possible relationships between the cloud…

Solar Update March 2012

by David Archibald Figure 1: Heliospheric Current Sheet Tilt Angle 1976 – 2012 The heliospheric current sheet tilt angle is currently at 67°. Solar maximum occurs when it reaches 74° – so a little bit further to go.

Solar cycle update: sunspots down, Ap index way down

The NOAA SWPC monthly solar cycle update has been published here, and after a big spike last month, the sunspot count is down again. There’s an even bigger drop though in the Ap geomagnetic index, as seen and discussed below the Continue reading line. 10.7 centimeter radio flux was down slightly too.

Solar Geomagnetic Ap Index Hits Zero

This is something you really don’t expect to see this far into solar cycle 24. But there it is, the Solar Dynamics Observatory satellite shows the sun as a cueball: The Ap index being zero, indicates that the sun’s magnetic field is low, and its magneto is idling rather than revving up as it should…
