NAME
+ +
+ + astro – print astronomical information
+ +
+

SYNOPSIS
+ +
+ + astro [ −dlpsatokm ] [ −c n ] [ −C d ] [ −e obj1 obj2 ]
+ +
+

DESCRIPTION
+ +
+ + Astro reports upcoming celestial events, by default for 24 hours + starting now. The options are:
+ d     Read the starting date. A prompt gives the input format.
+ l     Read the north latitude, west longitude, and elevation of the + observation point. A prompt gives the input format. If l is missing, + the initial position is read from the file /usr/local/plan9/sky/here.
+ c     Report for n (default 1) successive days.
+ C     Used with −c, set the interval to d days (or fractions of days).
+ e     Report distance between the centers of objects, in arc seconds, + during eclipses or occultations involving obj1 and obj2.
+ p     Print the positions of objects at the given time rather than + searching for interesting conjunctions. For each, the name is + followed by the right ascension (hours, minutes, seconds), declination + (degrees, minutes, seconds), azimuth (degrees), elevation (degrees), + and semidiameter (arc seconds). For the sun and + +
+ + moon, the magnitude is also printed. The first line of output + presents the date and time, sidereal time, and the latitude, longitude, + and elevation.
+ +
+ s     Print output in English words suitable for speech synthesizers.
+ a     Include a list of artificial earth satellites for interesting + events. (There are no orbital elements for the satellites, so + this option is not usable.)
+ t     Read ΔT from standard input. ΔT is the difference between ephemeris + and universal time (seconds) due to the slowing of the earth’s + rotation. ΔT is normally calculated from an empirical formula. + This option is needed only for very accurate timing of occultations, + eclipses, etc.
+ o     Search for stellar occultations.
+ k     Print times in local time (‘kitchen clock’) as described in the + timezone environment variable.
+ m     Includes a single comet in the list of objects. This is modified + (in the source) to refer to an approaching comet but in steady + state usually refers to the last interesting comet (currently + Hale-Bopp, C/1995 O1).
