65438+February 65438+April-Gemini meteor shower, as one of the three major meteor showers in the northern hemisphere, has always been known for its large and stable flow. And its maximum duration is long, no matter when the forecast is, we can see many meteors in the group that night. The annual active period of Gemini meteor shower is 17 from February 4th to 17 years. According to the forecast of the international meteor organization, it is most likely to appear at 9: 00 on June 4, Beijing time 15 this year. The radiant point of Gemini meteor shower is located near the second river of Alpha Gemini, and it will rise almost soon after sunset, so we can observe the meteors in its group all night. However, during the maximum period, the full moon and the convex moon in October of the lunar calendar will affect the observation most of the time, and moonlight will make some undercurrent stars difficult to be detected by the naked eye. Despite this, Gemini meteor shower is still the most noteworthy meteor shower in the whole year, but everyone must pay attention to cold and warmth when enjoying the meteor shower feast at the end of the year.

65438+February 23rd-The meteor shower in Ursa minor is a meteor group with the largest radiation point and the highest declination, which is very suitable for observation in the middle and high latitudes of the northern hemisphere. In 2006, 2007 and 2008, there were about 30 meteor showers every hour for three consecutive years. The meteor shower in Ursa minor is not expected to break out this year, and it is expected to appear around February 23rd, Beijing time 10, with no more than ten meteor showers per hour. Although the traffic is not large, it is catching up with the moonless night in the big era. For observers in most parts of China, the radiant point of the meteor shower in Ursa minor can be seen all night, and the better observation time is from the evening of the 22nd to the dawn of the 23rd. 65438+February 23rd-Mercury, the rarest planet in the west of Mercury, will meet you at a low altitude in the southeast before dawn at the end of the year. 12 On February 23rd, Mercury will reach its fourth westward distance this year, and its maximum angular distance from the sun is about 22. Due to the high declination of Mercury at this time, the horizon height can reach 16 at sunrise, and the brightness is about -0.4. Take Beijing as an example. The sunrise on the day of Xida distance is about 7: 30. The first hour to half an hour is a very good time to observe mercury. At the same time, we can still find a waning moon less than 4 below the oblique position of Mercury. The beautiful phenomenon of Mercury's full moon is rare, and it will also draw a perfect sentence number for the wonderful sky of 20 1 1.
