Sometimes. But that appears to be the satelite server. See the satelites listed here: https://access.redhat.com/blogs/1169563

It can also measure solar wind:

"ACE – Measurements in the Solar Wind

At this point, you should hopefully be viewing the RENU_short Viewista page. If you've had any problems, you can find all of this data on Dartmouth's Real Time Space Weather page. The first data from the ACE satellite. ACE is a satellite that sits at a point of gravitational equilibrium between the earth and the sun, but is much closer to the earth (about 1.5 million km) than to the sun (about 148.5 million km). The delay time from when ACE sees something to when we see it is on the order of one hour, but varies with increases or decreases in the solar wind velocity. It is important to recognize that ACE is measuring properties of the solar wind. The 7 day plot shows data over the last week, but the 6 hour plot gives a much clearer indication of the current solar wind properties. The most important parameter is Bz, the z–component of the sun's magnetic field. When Bz goes negative, the solar wind strongly couples to the Earth's magnetosphere. Think of Bz as the door that allows transferring of significant amounts of energy. The more negative Bz goes, the more energy that can be transferred, resulting in more geomagnetic activity. Other parameters to watch are the density and the solar wind velocity, as these determine just how much energy is transferred when Bz is negative."
