The establishment of SEAAN• Proposed in the SPS 5, the 26th IAU General
Assembly in Prague, August 2006
• 1st SEAAN meeting ð in conjunction with Siam
Physics Congress (SPC), Thai National
Astronomical Meeting (TNAM), 22-24 March

Timau National Observatory, Indonesia
Current Progress - Mid 2017
The observatory will be equipped with 4-meterclass optical telescope, sub-meter telescopes,
solar telescopes. Medium sized radio telescope isalso planned.
LAPAN and ITB have discussed with Kyoto
University about the possible realisation of themain telescope.
Segmented mirror technology is considered tobe suitable: lightweight, agile, reliable, and easier
to maintain.
● Procurement process: mid 2017.
● First light: 2020.
First generation instruments (tentative) include
modest CCD imager, fast camera, and medium
resolution spectrograph.

A new national observatory will be built at Mt.
Timau, East Timor, Indonesia where clear sky
fraction reaches 70%.
Ministry of Environment and Forestry just
granted permission to use conservation area.

Became an astronomer after WWII
Kept studying with the support by US
He has come to think that
Now it is our turn to support Asian countries
for developing astronomy in those countries
GAO should be a good method for realizing
such his will

Prof. Yoshihide Kozai
Director of GAO
1981-1988 Director of Tokyo Astron Obs.
1988-1991 President of IAU
1988-1994 Director of NAOJ
Sometimes expensive facilities are not usedvery actively due to the lack of local staff
who can use them properly.
Support to the people who really work withthe facilities is essentially important .

Key points
Exchange of human resource( the most important )Common understanding by
working together
Not only materials
