Let's observe!
Recommended observation period

December 1 to 31, 2020

The points of observation
  • Watch by the naked eye (You may observe with glasses or contact lenses).
  • Jupiter and Saturn can be seen in the low southwestern sky, so check in advance where that direction is not obscured from view.
  • We recommend you to watch Jupiter and Saturn not only in the evening of "extra-close" encounter but on a routine basis.
  • Looking at the starry sky for about 5 minutes, get accustomed to the outside environment (prepare for the night vision test).
  • The appearance of Jupiter and Saturn may change depending on the brightness of the sky (or the brightness of the surroundings), so it is recommended to try (observe) several times in the evening of the same day.
    (Because Jupiter is brighter and begins to appear earlier than Saturn, there is a period of time when only Jupiter can be seen regardless of night vision.)
  • If you live in the northan hemisphere, observe in warm clothes because it is a cold time.
  • Get enough sleep and observe in perfect health.
  • Ward off COVID-19, keep a distance between people, and observe.
  • When posting from a PC, be sure to record the observation date and time and the observation location.
