Darkness Text Report

The Darkness Text Report contains sun, moon, and darkness analysis times for each day in the date period selected. Times are accurate for the observer's location. Dates and times are given in the format selected in Preferences.

Printed and exported documents contain a header section that on-screen documents provide in the document settings pane of the document window. The header includes:

document name

observer's location (can be omitted from printing by activating the Print Saver)

darkness analysis time period (can be omitted from printing by activating the Print Saver)

The body of the report (on-screen, printed, and exported) is column oriented and the name of each column is listed below with a description.

Column name

Description

Dow

Day of week

Date

Month and day of month

AM Tw, Sun Rise, Sun Set, PM Tw

End of astronomical twilight, sun rise, sun set, and beginning of astronomical twilight. It is possible to have twilight all day, or none of the day. It is also possible for the sun to be up or down all day. In these cases, Tw is All am, All pm or None, and Rise/Set are Always up or Always down.

Moon Rise, Moon Set

Moon rise and set. None indicates that the moon does not rise or set during this 24 hour day. This is common because the sun and moon move through the sky at different speeds. It is also possible for the moon to be up or down all day. In these cases, Rise/Set are Always up or Always down.

Phase

The rounded percentage of the moon's disk that is illuminated at midnight on the date of the calculation. This result may indicate 0% on the date after the true new moon because the calculation is made for midnight on a given date. A similar situation exists for the full moon. The precise moment of the new or full moon can be calculated in a planet events document.

AM Dark, End

Start and End times of astronomical darkness between midnight and noon. None indicates that the sun never gets lower than 18° below the horizon and/or the moon is above the horizon during these hours.

PM Dark, End

Start and End times of astronomical darkness between midnight and noon. As with AM Darkness, None is also possible.
