Observers are reporting signs that epsilon Aurigae's light has plateau'd during the past week or so, suggestive that second contact was reached - that is, the dark disk now stretches across the nearly 1.5 astronomical unit diameter F star.   Exact time of second contact  can only be determined in hindsight, but the  change...
