History of the Hong Kong Observatory

The idea of setting up an astronomical observatory in Hong Kong was first initiated by the Surveyor General John Price in 1877. The main purpose was to provide accurate time services to the shipping community. Meanwhile, typhoons at that time were of great concern to Hong Kong. In 1879, the Royal Society presented another proposal to the British Colonial Office for the establishment of an observatory. It was considered that Hong Kong was 'favourably situated for the study of meteorology in general and typhoons in particular'. This proposal was subsequently improved and revised in 1881 by Major Henry Palmer, the Aide-de-camp to the Governor of Hong Kong, and became the blueprint for the establishment of the Observatory. After further revisions by Price, the proposal was eventually approved in 1882. Dr. W. Doberck was appointed Government Astronomer (the first director of the Observatory) and following his arrival in Hong Kong in the summer of 1883, the Hong Kong Observatory was established in the same year.

Early operations of the Observatory included meteorological observations, time service, magnetic observations, and a tropical cyclone warning service. In 1912, the title Royal Observatory, Hong Kong, was granted - a title that remained until 1 July 1997, when the original name was restored.

More than a century has elapsed since the establishment of the Hong Kong Observatory. The department has evolved in pace with the increasing expectations and the modern day requirements of the Hong Kong community. From time to time advanced technologies were introduced in the development of its services. In particular, the most noticeable events are :

Year Events
Early years of the Observatory
1883 Hong Kong Observatory was established.
1884 Started regular meteorological observations and published the China Coast Meteorological Register and Meteorological Register in the newspapers.

The Observatory instituted the tropical cyclone warning system, utilizing a visual signal system of drum, ball and cone (subsequently known as non-local storm signals) to inform masters of vessels leaving the port of Hong Kong about the position and movement of tropical cyclones. For the local public, a typhoon gun was used to warn imminent gale force winds brought about by tropical cyclones.

Magnetic observations of the horizontal and vertical forces and declination began.

The Observatory installed a three-inch transit telescope and two meridian markers in preparation for time services.
1885 The time ball was dropped for the first time at the Police Station at Tsim Sha Tsui. The dropping of the time ball was a means of providing the time signal to the public in the early years of the Observatory. The ball was raised half way up the mast at 12:55 p.m. each day and further raised to the top of the mast at 12:57 p.m.. The ball was then lowered at exactly 1 p.m.

Time Ball at Tsim Sha Tsui Police Station (1885-1907)

1933 With the introduction and wider use of time signals on radio broadcast, the time ball at Signal Hill was dismantled on 30 June.
1937 Aviation weather service commenced.

Hong Kong hosted the first Conference of the Regional Commission II of the International Meteorological Organization (IMO), the predecessor of the Regional Association II of the World Meteorological Organization.
