Query: Predicting Alpha Comae Berenices Time of Eclipse I: A 26 Year Binary
  will Eclipse within 2 weeks of 25 January 2015   The dwarf stars in the 26 year period binary Alpha Com are predicted to
eclipse each other in early 2015. Simulations of randomly selected orbital
parameters based on the most recently published orbital elements and
uncertainties show the eclipse will happen within 3 days of MJD 57047 (January
25, 2015; 1 sigma; all simulations fall within 2 weeks of this) and will have a
depth of several tenths of a magnitude. The eclipse will last between 28 and 45
hours, depending on the exact orbital parameters. Observers are encouraged to
monitor this unique event.
