Moon visible time forenotice instrument

Abstract

The invention discloses a moonrise and moonset predictor which comprises a base plate, wherein the base plate is a circular plate marked with the horizon, the sun, moon phase and the lunar calendar date, the geographical position and the time number; a rotating disk rotating around the center of the circular plate is arranged on the circular plate, the middle part of the rotating disk is fixedly connected with a rotating shaft, and the center part of the circular plate is provided with a shaft hole matching with the rotating shaft. The rotating disk is provided with a window which is opposite to the moon phase and the lunar calendar on the circular plate. When the moonrise and moonset predictor is in use, the lunar calendar is known, and then the rising moon phase and the rising time at night can be predicted; when in sunset, the moon is searched, and the calendar date of that day and the time predicting the moon are determined.

Description

technical field

[0001] The invention relates to a moon phase instrument, in particular to a moon visible time forecasting instrument for people to see the moon on the earth. Background technique

[0002] my country's Chang'e-1 lunar exploration satellite has been successfully launched to explore the wonderful lunar world. This makes people want to know more about the moon. Among them, the most curious thing is when can the moon be seen if it is not cloudy? Because we found that when the sun sets, sometimes the moon hangs in the western sky in a curved crescent shape, and sometimes it appears in the eastern horizon as a round bright moon. That is to say, the moon does not appear in the same position and appearance at the same time every day. The rising and falling times of the moon and the change of its cloudiness and waxing are regular. We hope to develop a moon visible time forecaster to Forecast the time and shape of the moon that can be seen.
