Object Detail
Whenever you select an object in the Catalog, Solar
System, or Sky Map form you get a Detail
form showing more information for this object.
The displayed information depends on the selected object. For some
objects you can even get more information with the up/down arrows.
The possible fields are:
- Rise, Trans, Set
- The local time when the object is rising, transiting, or setting.
These times are chosen that they show the transit nearest to the
currently selected time. So if you choose a time late in the evening
it is normal that all times are on the morning of the following
day.
A '+' or '-' sign denotes the following or preceding day, a small
circle denotes daylight savings time. When the object is circum
polar 'CirPl' is displayed, when it is never above horizon
'NvrUp'.
- RA, Dec
- The Right Ascension an Declination fields show the current
position of the object in celestial coordinates.
- Alt, Az
- Altitude and Azimuth fields show current position of the moon in
local coordinates. An Azimuth of 0 degrees means North.
- IllF
- The percentage of the moon or planet that is illuminated.
- Age
- How far along the moon is in the current cycle. When the age is
0%, a new lunar cycle has begun. The moon is full when it's age is
50%.
- Magnitude
- The brightness of the object in visual magnitude. The magnitude
is scaled logarithmically, a magnitude below 0 is very bright, a
magnitudes above 4 are visible with the naked eye only in a clear
night.
- Phase
- The phase angle is the angle Sun-Planet-Earth.
- Size
- The visual size of an objects in minutes
- Dist
- The distance of a planets in astronomical units (AU). One AU is
the mean distance Earth-Sun.
(Note that all information is in the context of
the currently selected location, date and time. See the Options panel for information on setting this
