"The sun's polar magnetic fields weaken, go to zero, and then emerge again with the opposite polarity," Stanford solar physicist Phil Scherrer said in a statement. "This is a regular part of the solar cycle.""
When the field hits zero it might be a good time for an RV experiment, if it could be timed correctly.
