Guest guest Posted November 15, 2001 Report Share Posted November 15, 2001 Repected guru's, OM. Please accept my submision of lesson Astronomical definitions and kindly point out my faults so that my learning can be fuirtful. SJVC Lesson 1 – Astronomical definitions Question #1 Explain the changing seasons and its connection to the above- mentioned astronomical factors. The visible changes in seasons are due to the Sun's yearly motion (Actually the Sun has no motion. The motion being mentioned here is the Sun's apparent motion relative to the earth's rotation) The motion of the sun in northern and southern hemisphere gives rise to various seasons. The sun's travel round the bhachakra is one solar year, also known as `AYANA'. Further the solar year can be divided into two parts or phases. Ø From the time sun's entry into the sign of Capricorn to the end of Gemini. This phase is called as Uttarayana. This also goes by the name of Saumayayana. Ø From the time sun's entry into Cancer to the end of Capricorn is called Dhashinayana. This is also called as Yamayayana. Thus the motion of Sun encompassing Uttarayana and Dhashinayana give rise to Ritu's or Seasons. The Ritu's are six in number. Each Ritu is for duration of 2 months. They are… 1. Shishir 2. Basant 3. Greeshma 4. Varsha 5. Sharad 6. Hemant. Question #2 There are some days of the year when the sun either doesn't rise or set above certain parts of the globe. Please explain this phenomenon. The structure of the earth is oval or egg shaped. This means that the earth's top and bottom end are flattened out. We also know that earth rotates once a day on its axis. At high latitudes signs have a prolonged exposure to sun. Question #3 Parasara mentions two classes of heavenly bodies: the moving and non- moving ones. Please explain, what will be the difference between their roles in astrological interpretation. The two classes of heavenly bodies can be classified into moving and non-moving. Non-movable heavenly bodies are called Nakshatras or asterisms. The movable class of heavenly bodies is called Grahas or planets. The apparent astronomical difference between these two classes is the fact that Grahas have rotation and Nakshatras are fixed points. This is a difference Astronomically. The Astrological difference is subtler. Nakshatras are fixed points in the bhachakra having inherent qualities of their own. They can also be visualized as being the permanent fixed path through which all planets within the 9-9 degrees of the zodiac belt. Each of these Nakshatra points has their own identity with regard to their qualities. Planets or Grahas having motion pass travel through this fixed path from one Nakshatra to the next one. Planets have their own inherent qualities. These inherent natural qualities of planets undergo a subtle change when they pass through each Nakshatra. This is the astrological significance. Question #4 If you are able to construct your own chart, please do it and explain as many astronomical principles from it as you can (terrestrial latitude/longitude, season, Sun's cycle, Sunrise/Sunset etc.). Also try to determine which planets are above and under the horizon in your chart. In which Ayana the Sun is? The details of my chart are below. 3rd Nov 1970. 8-40AM Place – Bangalore – India. Astronomical data. Latitude of the place of birth is 12Deg 58 min north Longitude of the place of birth is 77deg 36min East of Greenwich Season at the time of birth is Sharad. Lunar month at the time of birth is Karthika. Tithi is Sukla chaturthi. Sunrise is 6-13 AM Sun-set is 17-52. Sun is in dhaskinayana. In my horoscope the detail of planet positions are as follows. Lagna – Sc (East) Sun – Li (below Horizon) Moon – Sg (below Horizon) Mars – Vi (below Horizon) Merc – Li (below Horizon) Jup – Li (below Horizon) Venus – Li (below Horizon) Saturn – Ar (Horizon) Rahu – Aq (north - (Horizon)) Ketu – Leo (south – below horizon).
