As the eclipse magnitude is small, observers may need a telescope to observe this solar eclipse. A specialised solar filter or an indirect way such as the projection method is essential for solar observation. Inadequate ways to observe the Sun may result in severe ocular burns. The general public may also check the online platforms of the Hong Kong Space Museum to watch the live image of the solar eclipse on that day. The next partial solar eclipse in Hong Kong will occur on 22 July 2028, whose magnitude will even be smaller than that of this one.

Partial eclipse begins: the instant when the Moon’s limb contacts the Sun’s limb.

Greatest eclipse: the instant when the apparent centers of the Moon and the Sun are at the smallest separation. The eclipse magnitude reaches its maximum at this time.

Partial eclipse ends: the instant when the Moon’s limb leaves the Sun’s limb completely.

Eclipse magnitude: reflects how deep the Moon eclipses the Sun. The larger the magnitude is, the larger proportion of the Sun is covered.

The eclipse this time is a hybrid solar eclipse. In addition to the partial solar eclipse, there are some places on Earth where a total solar eclipse or annular solar eclipse can be observed. The central point of the eclipse is located at the South of the equator. The eclipse magnitude is larger when the observer is closer to the central point. In Hong Kong, the partial solar eclipse will begin around noon. It can be observed from many districts. However, the eclipse magnitude and duration will be slightly larger in the southeastern region. Interested observers may first consider places at Kowloon East or the eastern part of Hong Kong Island.

The partial solar eclipse begins at 12:34 pm, where the Sun is located at about 79 degrees above the southwest horizon at that time. The entire eclipse will end at 1:16 pm.

#AlreadyTomorrowInHongKong #香港| #香港太空館 #HongKongSpaceMuseum #March2023|#HKSpMActivity The #月掩金星 #LunarOccultation #Astronomy event of #金星 #Venus on 24th March 2023…..

Hong Kong SAR, China, People’s Republic of China will usher in an astronomical phenomenon of “moon occultation of Venus” on March 24, 2023. Since the orbital plane of the moon is very close to the orbital planes of the planets, if the moon covers the planets in the sky, it is called a “lunar occultation planet”. In addition, Venus is the celestial body in the solar system that is second only to the sun and the moon in brightness, so “lunar occultation of Venus” is relatively easy to observe and has attracted a lot of attention from astronomy observers.

The “moon occultation of Venus” will start at 7:47 pm and end at 8:53 pm, lasting about one hour and six minutes. At the time of “occlusion”, the moon is located in the northwest about 18 degrees above the horizon. Since both are quite bright, they can be observed directly with the naked eye, and binoculars or astronomical telescopes will have a clearer observation effect. At the time of “occlusion”, the moon will move to a position only 3.8 degrees above the horizon, and observers need to go to a place with almost no obstruction in the northwest to observe it.

A lunar occultation of Venus will occur in Hong Kong at night on March 24 (Friday). The Moon will move between the Earth and Venus at that time. We will not be able to observe Venus as it will be blocked by the Moon temporarily at that time.

The coming “Lunar Occultation of Venus” will begin at 7:47 pm and end at 8:53 pm, which will last for about one hour and six minutes. Since the Moon and Venus are quite bright, they can be observed directly with the naked eye. Both objects will appear close to the horizon, observers need to find a place with an almost completely unobstructed view towards the northwestern horizon.

Since Venus always appears close to the Sun, the lunar occultation of Venus mostly happen in day time. The next lunar occultation of Venus observable in Hong Kong during night time will be on May 31, 2063.

The above predictions are based on the Hong Kong Space Museum in Tsim Sha Tsui, Kowloon, Hong Kong as the reference point, and the occultation time may vary by tens of seconds in different places in Hong Kong.

The occultation begins near the east side of the Moon and ends near the west side. In fact, the visual motion of the Moon is much faster than that of Venus, but observations can also track the Moon to show the relative motion of Venus. Since Venus is located near the sun for a long time, lunar occultation of Venus generally occurs during the day. The next lunar occultation of Venus in the Hong Kong evening will be May 31, 2063.

It weighs more than 6,000 tons and covers an area as large as 23 basketball courts! Xinjiang Uygur Autonomous Region, China- People’s Republic begins construction of world’s largest mobile radio telescope….

​​Speaking of radio telescopes, we all think of “China Sky Eye”. This sky-viewing artifact located in the Dawodang depression of Pingtang County, Guizhou Province has a diameter of 500 meters. The full name is “500-meter Aperture Spherical Radio Telescope (FAST)” ”, its spherical observation area is 250,000 square meters, comparable to 30 standard football fields, far ahead of other radio telescopes in the world, but this radio stabilization is fixed, and its sky survey observation function relies on the rotation of the earth , it cannot directionally observe celestial objects at a certain position in the sky, so its observation function has certain limitations. Its sky survey observation function is unparalleled, but its directional observation function is very weak. Only the celestial body directly above it can be in its best position.

Compared to the “China Sky Eye” 110-meter large-aperture radio astronomical telescope project started in Xinjiang] On September 21, 2022, an event of great significance to my country’s astronomical field occurred in Shihezi Village, Banjiegou Town, Qitai County, Changji Hui Autonomous Prefecture, Xinjiang. ——The foundation stone of the 110-meter-aperture omnidirectional movable radio telescope project was laid here.

Observation location. Chinese Sky Eye So, in addition to this fixed spherical radio telescope, the more common is the omnidirectional movable spherical radio telescope. This kind of telescope can adjust the observation direction and position at will. Except for the part blocked by the earth, it is almost unobserved…..  The limitation of the position of celestial bodies, which is crucial for observing those celestial bodies that need to be studied for a long time.

So which is the largest mobile radio telescope in the world? The current name belongs to the Green Bank Radio Astronomy Telescope in the United States. It is located at the Green Bank Observatory in West Virginia, United States. This telescope is about 146 meters high, equivalent to the height of 49 floors, and weighs 7,700 tons. It is larger than the metal frame of the Eiffel Tower. (about 7,300 tons) is still heavy, equivalent to the weight of a medium and large destroyer, and it is also the largest land-based movable structure in the world. Green Bank Radio Telescope

​What is more special is that the active surface of the dish antenna is not a perfect circle, but an ellipse with a length of 110 meters and a width of 100 meters. It is also the omnidirectional movable radio telescope with the strongest observation ability in the world.

​However, according to a report by “CCTV News” on September 21, the world’s largest omnidirectional movable radio telescope is being built in Qitai County, Xinjiang, my country. The English QiTai radio Telescope, abbreviated as QTT) “has broken ground and started construction. It is a circular spherical radio telescope with a diameter of 110 meters, which is slightly larger than the Green Bank radio telescope in the United States.

Structural simulation diagram of odd radio telescope  Qitai Radio Telescope is built in the closed basin of Shihezi Pasture, Shihezi Village, Banjiegou Town, Qitai County, Xinjiang. It has a high altitude, a relatively dry climate, and is far away from densely populated towns. It is shielded by mountains and has good astronomical observations. condition.

​The scale of this giant sky-watching artifacts is also very large. It is expected that its antenna will exceed the height of a 35-story building, its weight will reach more than 6,000 tons, and its spherical aperture area is equivalent to 23 basketball courts. It can achieve high quality from 150MHz to 115GHz. During the observation, the surface shape accuracy can reach 0.3 mm and the pointing accuracy is 2.5 arc seconds, which can observe the celestial bodies with very dim wireless signals in the distant universe with high precision. Its observation objects include black holes, quasars, fast radio bursts, dark matter, gravitational waves, and even alien civilization signals.

 ​It is estimated that the construction of this telescope will take 6 years. The media said that it will become the world’s largest and most accurate 100-meter omnidirectional movable radio telescope after completion. It will not last too long, because an omnidirectional movable radio telescope with a diameter of 120 meters, the Jingdong 120m Pulsar Radio Telescope (JRT), is being built in the Wuliang Mountains in Dali, Yunnan, my country. The giant telescope is located in Xujiaba, Taizhong Town, Jingdong County, Pu’er City, Yunnan Province. It is the largest omnidirectional movable radio telescope currently under construction in the world. Jingdong 120m Pulsar Radio Telescope

​I believe that with the use of these astronomical observation “power tools” with the title of “world first”, our achievements in astronomical exploration will gradually become world first.

#MadeInChina #中國製造 #中國 |#西藏 #西藏天文馆 #TibetPlanetarium #June2022 |#Lhasa The world’s highest-altitude planetarium Observatory telescope – world’s largest refracting optical astronomical telescope ready year  2024,  – under construction, which will provide space early warning services for space activities…#TibetAutonomousRegion #China #PeoplesRepublicOfChina ….

西藏天文馆 Currently at the moment in Lhasa the region capital of Tibet Autonomous Region of China- People’s Republic of China the Construction of the world’s highest – The world’s highest-altitude planetarium, the西藏天文馆Tibet Planetarium, started construction in Lhasa on June 12. It is reported that the roof of the planetarium will be equipped with a refracting optical astronomical telescope with a diameter of 1.06 meters, which will also be the largest refracting optical astronomical telescope in the world. The planetarium has a total construction area of ​​11,571.9 square meters and is expected to be completed in June 2024. The roof of the planetarium will be equipped with a refracting optical telescope with a diameter of about 1.06 meters. This astronomical telescope will also surpass the 1.02-meter-diameter refractor telescope of the Yerkes Observatory in the United States and become the world’s largest refracting astronomical telescope. …


This one-meter-class refractor telescope can monitor variable stars, poor photometry of binary stars, and supernova monitoring. The scope of monitoring includes celestial bodies in the solar system, stars in the Milky Way, and even some nearby galaxies in the outer reaches of the Milky Way can also be observed.
In addition, in scientific research work, this one-meter-class refracting telescope will be used for space target observation, providing space early warning services for my country’s space launch activities and the on-orbit operation of spacecraft.


“Space debris and space junk are being monitored on a global scale, and this monitoring network requires a large number of space observation facilities such as telescopes to work together. The scientific goals of our one-meter-class refractor telescope also involve near-Earth detection in space. The monitoring activities of small celestial bodies and space debris are part of the entire monitoring network.” Wang Junjie said that there is no professional large-scale astronomical observation telescope in the vast Tibet area, and the space monitoring network needs to deploy monitoring equipment closely. The high-level refractor telescope is equivalent to filling the “blind area” of China’s space monitoring network. It will become an important part of the entire monitoring system. The monitoring data obtained will also be used together with the data of other monitoring facilities to calculate the space flight. The construction of the Tibet Planetarium in the orbit of the object 

The special geographical and climatic advantages of Tibet can also facilitate astronomical observations. In order to reduce the influence of atmospheric, weather and other factors on astronomical observation activities, astronomical observation facilities should preferably be located in places with higher altitudes, more sunshine and less rain, and less light pollution. The characteristics of high altitude, sunny days, low population density and high atmospheric visibility in Lhasa will be conducive to astronomical observations.

  In addition, the Tibet Planetarium after its completion will also undertake a special mission, that is, to carry out astronomical science popularization activities that are easy for the public, especially young people to participate in and accept, and popularize astronomical science knowledge through exhibitions, training, experiments, video broadcasts, lectures, etc. , to spread scientific ideas.

 ”The world’s highest-altitude planetarium, coupled with the world’s largest refracting optical astronomical telescope, will have a huge appeal to local people, domestic and foreign tourists, and astronomy enthusiasts. The scientific and cultural literacy of the public plays a unique and important role.” Wang Junjie said that he believed that the Tibet Planetarium would become a new local Internet celebrity landmark, attracting local people and global tourists to visit.

  According to the operation data of the Tibet Natural Science Museum over the years, the annual reception of the Tibet Planetarium is expected to reach more than 100,000 people, and more than 100,000 people can receive astronomical science popularization education every year.

  Wang Junjie said that in recent years, the astronomical undertakings in Tibet have been developing continuously, from the Tibet Yangbajing Observatory, the first professional observatory in Tibet, the National Astronomical Observatory, to the Ali Observatory of the National Astronomical Observatory in western Tibet. The former has a submillimeter-wave telescope in cooperation with Germany, which mainly explores star formation, organic molecules, etc. The latter is still under further construction, including gravitational wave telescopes, optical telescopes and other equipment.
