# months_observable¶

astroplan.months_observable(constraints, observer, targets, time_grid_resolution=<Quantity 0.5 h>)[source]

Determines which month the specified targets are observable for a specific observer, given the supplied constriants.

Parameters: constraints : list or Constraint Observational constraint(s) observer : Observer The observer who has constraints constraints targets : {list, SkyCoord, FixedTarget} Target or list of targets time_grid_resolution : Quantity (optional) If time_range is specified, determine whether constraints are met between test times in time_range by checking constraint at linearly-spaced times separated by time_resolution. Default is 0.5 hours. observable_months : list List of sets of unique integers representing each month that a target is observable, one set per target. These integers are 1-based so that January maps to 1, February maps to 2, etc.
