These altitude/time charts provide the most complete information about what is
visible in the sky and when.
Each horizontal stripe below represents the 24 hours of the day, from noon on
one day (far left) to noon the following day (far right). The color of the
stripe indicates the altitude of that object at any particular moment in time.
When the stripe is black or red, the object is low in the sky and may be hard
to see. When it is yellow or green, it is virtually overhead.
Specifying a particular time of day (above) will limit the search to objects
which are well-placed for viewing at that time, and also put a purple marker at
that time along each stripe.
Stripes which are yellow or green at the point marked by the purple line will
be those best placed for observing.
