Philippine Astronomical Society Overnight Stargazing

•April 15, 2014 • Leave a Comment

Announcement from Philippine Astronomical Society (PAS):

Bring: Tent, warm clothing, pack dinner/snacks/breakfast, flashlight, umbrella, raincoat (in case of rain and if you have no tent), drinking water. PAS will bring telescopes, binoculars, green laser; but you may bring your own if you want.

Note – The area is ultra-dark with no lighting at all, so this warrants the best and clearest sky condition for stargazing with zero light pollution. Please bring your flashlight though for mobility in the area.

Note also that cell signals in that area are weak and unstable, so it’s difficult to call your friends already in the site if you are coming late and separately from the group. Please be aware of this if you cannot help it but come later.

The National Astronomy Week in the Philippines is an annual event held every third week of February. For this year, a number of activities have been prepared by various astronomical institutions and organizations in the country. Please attend and participate in this celebration. Kindly check this page again for updates of the list of activities.

Happy NAW! To the stars!


Free planetarium shows at PAGASA (Science Garden) and  Stargazing/Telescoping Sessions at PAGASA Observatory (UP Diliman) from 17-21 February 2014.

The National Astronomy Week Opening Ceremony is reschedule to FEBRUARY 22, 2014 (SATURDAY). Same program flow shall be followed on that day.

The National Astronomy Week Opening Ceremony is postponed due to anticipated heavy traffic as Iglesia ni Cristo holds its World Wide Walk. The University of Santo Tomas also declared a suspension of classes and office the same day.

We apologies for the inconvenience that this may cause but this beyond PAS. For inquiries and clarification, please don’t hesitate to contact us at or at 09175969024, 09473370560

January 13, 2014 Lunar Halo Philippines

•January 14, 2014 • 2 Comments

I can’t help not to feature some photos taken by Filipinos who looked up and took time to image the beautiful 22 degree lunar halo on monday night. I wish I was in Manila to witness the event!

For those who are asking what causes the atmospheric phenomenon, here’s a good explanation by Gary Andreassen, a member of Astronomical League of the Philippines:

A moon halo is produced by the ice cystals in cirrostratus clouds (5–10 km high) in the upper troposphere. The light of the moon is reflected and refracted by the ice crystals and may split up into colors because of dispersion. The crystals behave like prisms and mirrors refracting and reflecting moonlight sending shafts of light in particular directions.
A moon halo often means that rain is going to fall within the next 24 hours as the cirrostratus clouds that cause them can signify an approaching frontal system. Moon halos are actually quite common in the Philippines this time of year.

Philippine Astronomical Society’s (PAS) Geminid Meteor Shower 2013 Observation and Christmas Party

Repost from PAS Facebook Group:

December 2013 Monthly Meeting, Geminid Meteor Shower Observation and PAS Christmas Party

Venue: Ateneo De Manila University, Quezon City
Date & Time: December 14, 2013, 3:00PM – December 15, 2013, 6:00AM

This event is open to all public and free of charge. This is an invitation to all astronomy- and astrophysics-enthusiasts. Join us as we explore cosmic ray particles and microwave remote sensing, and together let us observe the night sky for the Geminid meteor shower.

3:00 pm – 3:15 pm Registration
Venue: Conference Room, Social Science Building, ADMU

3:15 pm – 4:00 pm Ghost Particles from Outer Space
by Engr. Camilo Dacanay

Between high-energy physics and astrophysics, the study of cosmic ray particles remained offshore. The study of this entity has been recently revitalized partly due to advances in experimental techniques, discoveries of structure in its spectrum, and most of all, the decay-long debate in scientific community on its major role as the major factor of climate change. This is part 1 of the 3 part series lectures dedicated to students in physics, astronomy, meteorology, environmental science and science enthusiasts.

4:00 pm – 4:45 pm Lunar Surface Characterization and its Water-Ice Deposits Using Radar Polarimetry
by Ms. Margie Parinas

Water particles cannot be produced on the Lunar environment but may originate from the debris of comets or meteorites or even from solar wind. This leads to the creation of cold traps.The introduction of the radar polarimetry gives the observers an opportunity to characterize the surface’s slope, directionality and dielectric constant. Using Circular Polarization Ratio, and m-chi decomposition, this study aims to characterize the Lunar surface using MiniSAR circular polarization.

4:45 pm – 5:00 pm Socialization

8:00 pm – 6:00 am Geminids Observation and PAS Christmas Party
Venue: Roof deck, Manila Observatory, ADMU

PAS annual observation for the Geminid meteor shower has been a tradition for the PASers to observe the night sky together as we celebrate our Christmas party. It’s a potluck event and open to the public. Attendees are encouraged to bring their jackets/blankets, mats, and insect repellant for the observation.
