Position of Jupiter


Once a week or so, use your naked eye and/or binoculars to locate Jupiter’s position relative to the background stars shown below.  Mark its position with a cross: “+”, and write the date (HST) in very small numbers next to it.  USE PENCIL!  Make observations approximately once a week, for as many weeks as possible.  Observations may be made in lab or at home.  (This will become part of a larger Positions of Planets project, to be provided later this semester.) 


This is a 22˚´25˚ field of view.  North is up; west is to the right.  Most of the region shown belongs to the constellation Capricornus, and the constellations at the top (to the north) are Aquarius and Aquila.  All stars of magnitude 6.5 or brighter are shown: the faintest of these are too faint to be seen with the naked eye (especially in the city), but all of them should be visible through binoculars.
