| Any Mercury Maximum Elongation (e.g. maximum West on Sep 28, 2016) coincides with increased solar storminess, particularly within a few days either way of the key points within the cycle. Superior (far side) conjunctions of the Sun and Mercury (e.g. Oct 27, 2016) are typically indications of bursts of solar activity (solar flares, coronal holes and coronal mass ejections (CMEs)) some two weeks later, give or take a few days either way.
