  • Rise and Set Algorithm for a given Lattitude Longitude and RA Dec
    A simplified implementation of the Rise, Set, and Transit algorithm from the book Astronomical Algorithms by Jean Meeus For objects whose position changes significantly over the course of they day (e g the Sun or Moon) it's more accurate to iteravley re-compute the object's position for each specific time for the event you're interested in
  • Rise Set Transit Times for Major Solar System Bodies and Bright Stars
    This data service provides the times of rise, set, and transit for the major solar system bodies and selected bright stars The output table also includes azimuth at rise and set, as well
  • Need Simple equation for Rise, Transit, and Set time
    Current Time Output: Rise Time Transit Time Set Time (and, hopefully) max elevation at transit (and, hopefully) current alt and az of object It seems like this should be a simple relationship, but I haven't been able to find it
  • Transit Algorithms - California Institute of Technology
    Rise Set Times For ground-based observations (only), target rise, target set, and twilight times are calculated for the night of each observable transit as follows: Target Rise and Target Set The positive and negative local hour angle limits at which the target rises above at sets below the requested altitude limit are calculated
  • Asteroid (NEO) 2025 LV | TheSkyLive
    The current Right Ascension is 17h 17m 59s and the Declination is +01° 39’ 47 ” Max altitude: 33 3° TRANSIT 0:51 Rise and Set Times: Asteroid (NEO) 2025 LV's rise and set times from your location Interactive Sky Map: planetarium-style interactive visualization of Asteroid
  • Celestial Navigation: Special Techniques
    From the Nautical Almanac, get the Declination at 12:00 UT (Dec) and the Greenwich Culmination Time (T culmination) of the celestial object for which the Rise and Set Times have to be determined
  • How to compute rise set times and altitude above horizon
    In most countries an altitude of -0 833 degrees is used to compute sunrise set times (Sun's upper limb touches the horizon; atmospheric refraction accounted for)
  • Sheets - Stargazing
    Celestial Rise Set Times (USNO) This form creates a rise transit set table for a specified celestial object From the U S Naval Observatory, Astronomical Applications Department Celestial Navigation Data (USNO) displays position from observations of the altitudes of celestial bodies from the U S Naval Observatory, Astronomical Applications
  • How to calculate when a star will rise and set - George Mason University
    Arcturus will rise 4 7 hours before it reaches the meridian and set 7 3 hours after it passes the meridian That is, it will rise 7 3 hours before LST = 14H 14M and set 7 3 hours later than that time So when is LST = 14H14M on Jan 20?
  • Positional Astronomy: lt;br gt;Sunrise, sunset and twilight
    Since refraction affects zenith angle, it changes both the Right Ascension and declination of an object It also affects the time the object appears to rise and set The standard formula for the altitude of an object is: If a = 0° (the object is on horizon), then we have: the time between the object crossing the horizon, and crossing the meridian
