Austrian sky calendar

The Celestial Calendar and two other yearbooks of similar content. The Heidelberg yearbook was included in the Astronomical Ephemeris in 1960 .

The sky calendar was an astronomical yearbook for Austria, but it was also suitable for southern Germany and the neighboring countries to the east. It has been published every autumn since 1957 and was published by the Astronomical Office of the Austrian Astro Association under the direction of Hermann Mucke . After his death in March 2019, the celestial calendar was discontinued. As a successor, the Astronomical Almanac for Austria was launched in 2020 .

The yearbook had around 140 pages and was printed in a handy A5 landscape format. It contained all the important data on the solar system and the starry sky for amateur astronomers and was designed for precise forecasting of the geographical latitude of Vienna (also usable for Munich ). A special focus was observational astronomy with the naked eye . The table intervals were well adapted to the celestial bodies and designed for rapid interpolation in the head .

Content:

• Explanations and chronology
• Monthly overviews with
  • Sidereal time
  • Rise / set of the sun and moon
  • Right ascension and declination of the moon
  • Visibility of planets (e.g. Mercury in the evening until March 13th in Pisces )
  • Special celestial constellations, such as the most important moon phases, culmination and maximum elongation of planets or information about when celestial bodies come particularly close (e.g. Venus 3 ° north of Jupiter on March 15, 2012 at 12 o'clock )
• Constellation maps for each month
• Sun and moon (coordinates, diameter, physical data)
• Large planets and Pluto (right ascension, declination, apparent brightness, elongation , angular diameter, distance from the earth, rise, culmination and setting)
• Galilean moons of Jupiter , large moons of Saturn ( Rhea , Titan , Japetus ), Saturn's ring
• Minor planets (e.g. Pallas , Ceres , Vesta , etc.) and bright stars
• Star occultations by the moon (for Vienna and Innsbruck )
• Solar and lunar eclipses
• Apparent star locations (40 bright fundamental stars )
• Transfer of location-dependent data (geographical correction)
• Twilight times for all nine Austrian provincial capitals
• Astro Association projects and observation programs
