As the leading organization in field of observational
astronomy in the country, the Astronomical League of the
Philippines conducts observing campaigns for systematic
and close monitoring of celestial objects or events.
Data from these observing campaigns will be used
in research and published in scientific journals.
Jupiter Opposition Campaign
Planetary oppositions are perhaps one of the most
observed celestial phenomena in the sky. Rogers (1995)
described the Opposition as the period when the
planet is directly opposite the sun in the sky, thus,
astronomers are able to view the planet overhead during
midnight, with its highest altitude.
On October 29th, the planet Jupiter will have a close
approach with Earth in terms of their orbital paths,
enabling observers to document the Opposition of
The ALP is calling for observations (reports,
sketches and/or images) of this event. For submissions,
please include details of the instrument used, time,
location, sky condition and other notable entries. Send
the report to

"Jupiter Opposition 2011".
