摘要：

We present solar wind trends observed by STEREO-A PLASTIC during Carrington Rotations 2053-2090 (February 2007 to December 2009) in relation to the current solar cycle conditions. The solar wind speed, mass number, and iron average charge state all showed a decline in the latter half of the survey period, during the time of minimal sunspot area, a retreat of the polar coronal holes (but with occasional isolated coronal holes) and a flattening of the neutral line.
