TOTAL LUNAR ECLIPSE OF JANUARY 21 2019

Helio C. Vital

Exhibiting an apparent diameter larger than in most eclipses, the Moon will cross the northern hemisphere of Earth`s umbral shadow during a relatively shallow and colorful eclipse.

Well positioned in American skies, it will encourage observers to estimate its brightness, either to be expressed in visual magnitudes (m~-2.6) or Danjon Numbers (L~3.0),

and also to time crater contacts as it crosses Earth`s shadow, so that we can calculate the fraction contributed by the atmosphere to Earth`s umbra.

An stratosphere relatively free of volcanic aerosols will conspire to provide us with a beautiful eclipse, including the bluish ozone fringe that often heralds the onset of totality.

Times for the major eclipse phases are listed below.
