Research area  (1): Astronomy
In accordance with the remarkable progress in
astronomy and astrophysics, it has become an
urgent issue to publicize the latest results
of astronomical research and the precise
information on celestial phenomena via a wide
variety of communication media, such as the
Internet or the so-called multi-media products.
In order to meet this requirement, the Public
Relations Center was established in 1998 April.
The Center is aimed to be core group within the
NAO to provocate the observatory's scientific
achievements to the public, to collect a variety
of astronomical information, to release some
selected topics with explanatory comments, and
to promote the understandings by citizens on
astronomyin general. The Center comprises six
sections; Public Relations Office, Outreach
Office, Ephemeris Computation Office, Library,
Publications Section, and Administration Team
[Telescope for Social Education]
A telescope dedicated to social education is
a 50cm reflector of the fork mounting type. It
is open to the public to view popular astronomical
objects. The telescope is operated by the Public
Relations Office.
Public gatherings are held on the nights of the
2nd Friday and the 4th Saturday of each month.
It is also used for the exercise of astronomical
observations in the graduate and undergraduate
classes during the course of extracurricular
activities, and in adult-education classes as
well on demand.
[Calendar and Ephemeris Compilation]
The Ephemeris Computation Office of the Public
Relations Center compiles the Calendar and
Ephemeris every year. It includes tables of
prositions of the Sun, Moon, and planets, the
times of sunrise and sunset, and other astronomical
phenomena. The Calendar and Ephemeris is made
available to the public through Governmental
Notices, as a part of Annual Science Handbook,
and via the observatory's web site. The Ephemeris
Computation Office also carries out theoretical
studies of the motions of celestial bodies in
the solar system and historical studies of old
Japanese, Chinese, and some Asian Ephemerides.
