ASTRONOMY



Telescoping and stargazing 
The PAGASA Astronomical Observatory is located inside the campus of the University of the Philippines, Diliman, Quezon City, conducts stargazing and telescoping sessions to interested astronomy enthusiasts, upon request. The session can either be conducted at the Observatory or at a specified venue of the requesting party/ individual. Letter of request should reach the Office of the Chief, Space Science and Astronomy Section, at least two weeks earlier than scheduled time, especially those, which will be conducted outside the PAGASA Observatory to allow the processing of necessary documents. The request letter can be addressed to:

Dr. Vicente B. Malano
Acting Administrator, PAGASA
Science Garden
Agham Road, Diliman
Quezon City, Philippines 1100

ATTENTION: Engr. Dario L. dela Cruz
                       Chief, SSAS

During the previous years, the 30-cm reflector-type telescope, which was permanently installed at the Observatory dome, is being used for the telescoping sessions. However, in May 2001, the Japanese Government donated a computer-based 45-cm telescope and was installed at the Observatory. Starting on February 16, 2003, the start of the celebration of the National Astronomy Week, the telescope is open for public use, after a series of adjustments made by the Japanese technicians.

Provided that the sky is clear, visitors can expect to have a glimpse of the famous bright stars like Vega and Sirius during the stargazing session. Planets such as Jupiter, Venus, Saturn, Mercury and Mars, including their satellites and the Moon can also be observed.

For residents of the cities of Davao, Cagayan de Oro, Cebu and Legazpi, stargazing and telescoping sessions can also be conducted at the PAGASA regional centers located in their area. One (1) 25-cm telescope in each of the above-mentioned sites are available for use. These telescopes were procured in May 1998 through the Grant-in-aid (GIA) project of the Department of Science and Technology (DOST), which is entitled "Promotion of Astronomy".

 

Stars and Constellations

The Square of Pegasus ( an asterism of the constellation of Andromeda, the Chained Maiden which is made up of four stars of nearly equal brightness namely: Scheat, Alpheratz, Markab and Algenib) takes center stage in the Philippine night sky after sunset, which is a sign of the arrival of the northern fall. Northeast of it lies the Andromeda Galaxy (M31), the closest large spiral galaxy to the Milky Way Galaxy as shown in Figures 1 & 1a. Under clear skies and with the aid of a star map and familiarity with the surrounding background stars, it can be seen as an elongated misty patch with the naked eye and can be easily viewed through binoculars and telescopes. The splendid W formation of stars known as the constellation of Cassiopeia, the wife of King Cepheus and the mother of Andromeda in the Greek mythology, lies to the left, while the constellation of Pisces, the Fish can be found at the lower right of of Pegasus.

The famous equilateral triangle in the sky, known as the Winter Triangle rises after midnight. The Triangle formed by the stars is composed of Betelgeuse, the super giant red star and the prominent star of the famous constellation Orion, (the Mighty Hunter), Sirius, the brightest star in the sky of the constellation Canis Major (the Big Dog), and Procyon, the brightest star of the constellation Canis Minor (the Little Dog).

Meteor Shower


The October Orionids meteor shower will be active from 17-25 October 2018. At maximum rates, the shower may reach 15 meteors per hour that may be observed at favorable sky condition, but sometimes there are lulls even during the traditional maximum peak nights of 21-22 October 2018. The Earth is passing through the stream of debris left behind by Comet Halley, the parent comet of the Orionid shower. The radiant of the shower will be observed north of Betelgeuse as shown in Figures 2 & 2a.

Planets Whereabouts
 
On 01 October at 6:00 PM, Venus and Jupiter, will be seen dazzling brightly at magnitude -4.80 and -1.80 and will be located at about 16 and 30 degrees high in the west southwestern horizon, respectively. Venus will lie among the background stars of the constellation Virgo, the Virgin, while Jupiter, the largest planet in the solar system, will be positioned among the stars of the constellation, Libra, the Scale.

Planets Mars and Saturn can be observed at altitudes of about 44° and 52° in the south southeastern horizon and can be found among the background stars of the constellation Capricornus, the Sea-Goat and Sagittarius, the Archer shining at magnitudes -1.30 and +0.50, respectively. The Saturn system holds more than 60 satellites or moons, of which seven (7) glow brightly enough to show through moderate-aperture telescopes. Saturn’s Titan, the largest and brightest satellite, which shines at magnitude +8.4 can be easily seen through any optical instrument. It orbits Saturn once every 16 days.

On the same date at 8:00 P.M., Neptune will be located 50 degrees above the southeastern horizon among the background stars of the constellation Aquarius, the Water-Bearer with a magnitude of +7.80. Meanwhile, its fellow gas giant, Uranus, will be seen standing at about 15° in the east northeastern horizon glowing feebly at magnitude +5.70. It will lie among the background stars of the constellation Aries, the Ram. Observing Neptune and Uranus will require a binocular or a telescope and a starmap under dark and clear sky condition.

Mercury, the nearest planet to the Sun will be out for observation during the month due to its proximity to the Sun.

Figure 3 shows how to compare apparent magnitudes of celestial bodies such as planets and stars.

Issue for October 2018
The October Orionids meteor shower will be active from October 17-25, 2017.

The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) is mandated by law, as the government agency tasked to keep and disseminate the Philippine Standard Time (PhST). 

The PAGASA Astronomical Observatory which is located inside the campus of the University of the Philippines, Diliman, Quezon City.  It is equipped with a 45-cm. computer-based telescope donated by the Japanese Government thru its cultural- grant-aid program.  It is the biggest ever acquired by the PAGASA since the establishment of the observatory in 1954 and is now the largest operational telescope in the country.  It is very powerful that astronomers and astronomy enthusiasts may now conduct effective observations of stellar bodies and other distant space objects.

The Planetarium at the Science Garden has an 88-seating capacity.  It offers an ideal setting for all kinds of cosmic educational tours, whose most important task is to give the scientific concept of the Universe to the general public, and to elementary and high school students.  This concept includes the size and content of the observed universe, its creation, history and possible future, the development of the solar system.

The history of astronomy in the Philippines since it started in 1897 will be described.  The development of astronomical resources, activities and education after its hundred years of existence will be emphasized.



The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) is mandated by law, as the government agency which is tasked to keep and disseminate the Philippine Standard Time (PhST). Section 6 of Batas Pambansa Blg. 8, defining the metric system in the country, states that: "PAGASA shall be responsible in the establishment, maintenance and operation of the National Standard for the second of time".

Another law is Presidential Decree 1149, assigning PAGASA as the official agency that will handle the dissemination of the Philippine Standard Time (PST). Recently, the Philippine Standard Time Act was created.  Later, its Implementing Rules and Regulations was also created.

Steps in Time Synchronization Using PAGASA NTP Server

Philippine Standard Time Act of 2013 (Republic Act No.10535)
Implementing Rules and Regulations of Republic Act No.10535

Disclaimer: Internet is one of the main modes by which PAGASA disseminates the Philippine Standard Time (PhST). There may be discrepancies with the PhST displayed here as compared to the PAGASA clock; the major causes being the internet transmission delay and the computer workload of the computer you are using. For a more precise clock synchronization, please call (+632) 9291237.


Republic Act 10535
The Philippine Standard Time (PhST)

1.    What is Republic Act No. 10535?

It is "The Philippine Standard Time (PhST) Act of 2013". This law sets the PhST in all official sources throughout the country, provide funds for the installation, and maintenance of synchronized time devices to be displayed in key public places, and to declare the first week of every year as National Time Consciousness Week (NSTW)

The Philippine Standard Time has the acronym PhST to distinguish it from the Pacific Standard Time (PST).

2.    When was it passed into law and who signed it?

It was passed into law last May 15, 2013 and signed by President Benigno S. Aquino III.

3.    What does it aim to promote?

The spirit behind the Philippine Standard Time touches on both technical and cultural aspects. The technical aspects aims to sync all time devices in the country so that its 7, 107 islands will have common time. Meanwhile, the cultural aspect aims to modify the so-called "Filipino time" (later than the scheduled time) attitude and develop the habit of being punctual as a show of respect to other people and to the value of time.

4.    Where can the general public get the PhST?

The PhST is generally sourced from DOST-Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA), the official time keeper of the country. Specifically, the PhST can be accessed from the PAGASA Astronomical Observatory, PAGASA Forecasting Center or the PAGASA ICT group;

Other institutions that can provide the PhST are the following:

- DOST agencies, and regional and provincial offices, including their wbsites;

- All PAGASA Regional and Field Stations;

- Internet, use of Network Time Protocol (NTP) Server System located in PAGASA website;

- Any of the National and Local government offices;

- Government and private television stations, and government and private radio stations;

- Other reliable means that provide accurate PhST.

5.    Who are required to display and comply with the PhST?

The following should display the PhST:

- National government agencies including State Universities and Colleges (SUCs) and Government Owned and Controlled Corporations (GOCCs);

- Local Government Units;

- Government television and rdio stations;

- Private television and radio stations;

- Private corporations/ agencies;

- Peoples's organizations, non-government organizations and civil society groups.

- Airports, seaports, expressways; and government electronic boards and similar establishments.

At least once a month, all of these offices, through their information and communication technology units or the equivalent, shall coordinate with PAGASA's Time Service Unit to synchronize their official timepieaces and devices.

6.    Who is tasked to monitor, maintain and disseminate the PhST?

PAGASA's Time Service Unit, in coordination with the Department of Science and Technology (DOST).

7.    What are the time devicces required to display PhST in acordance with the official time being provided by the PAGASA using its Network Time Protocol (NTP)?

Official time devices, including but limited to:

- bundy clocks

- displayed clocks

- chronomeers

- quartz clocks

Procurement of these time devices is supervised by the DOST, and the required specifications are issued PAGASA.

8.    Where should the PhST displayed?

It should be prominently displayed in areas readily accesible to the general public.

9.    Do all time devices have to be exactly in sync with the PhST?

Time deviation of plus (+) or minus (-) five (5) seconds with the PhST is acceptable.

10.Private television and radio stations are required to display and broadcast the PhST. What if they fail to calibrate and sychronize their time devices?

Broadcast stations that fail to comply with the requirements of PhST will have the following penalty:

*First Offense - Fine of not less than thirty thousand (Php 30, 000.00) pesos but not more that fifty thousand (Php 50, 000.00) pesos.

*Second Offense - Revocation and cancellation of franchise to operate

The collected penalty will be deposited in the general fund of the National Treasury.

11.What if the government employee or officer responsible for the implementation of the PhST fails to calibrate and synchronize the devices with PhST?

The employee or officer shall be administratively liable without prejudice to any civil or criminal liability that maybe appropriately imposed.

12.How will the PhST be promoted to Filipinos?

To promote awareness on the Philippine Standard Time, the government institutionalized the "National Time Consciouseness Week" to be celebrated yearly every first week of January.

PAGASA and the Science and Technology Information Institute (STII) of the DOST, in collaboration with government agencies, shall organize activities for the observance of the National Time Consciouseness Week (NSTW). Government agencies through the CSC shall be encouraged to issue the necessary guidelines to all government offices to follow the PhST.

In the celebration week, the pubic is likewise required to participate and cooperate in the activities, and encouraged to practice and promote a culture of punctuality and wise time management.
