A long duration C9 solar flare took place yesterday morning near sunspot region 2297 and launched a partial halo coronal mass ejection into space. While it is not a full halo coronal mass ejection, the coronal mass ejection was nonetheless very wide and caused an increase in the protons and electrons at Earth meaning that this coronal mass ejection will likely arrive at Earth. Based on the ejecta speed, the coronal mass ejection could arrive during the UTC evening hours of 17 March and cause a minor G1 geomagnetic storm.
