Orion, the Hunter, is one of the brightest and most recognizable constellations in the night sky during this month. Orion contains a number of famous nebulae, two of which are the Orion Nebula (M42) and the Horsehead Nebula. Two of the ten brightest stars in the sky are located in the constellation Orion. Rigel, the brightest star in Orion, is the sixth brightest star in the sky, while Betelgeuse, Orion’s second brightest star, is the eighth brightest star in the sky [2, 4].

The Orion Nebula (M42), the Crab Nebula (M1), the Pleiades (M45), the Hyades cluster, and the Large Magellanic Cloud are the most prominent astronomical targets for the month of January . Figure 2 shows the location of some of the deep-sky objects and bright stars in the constellation Orion and Taurus.
Mars will be readily visible in the evening sky just after sunset. On January 4 at 3:51 PM, the Moon and Mars will approach closely, passing 0° 32" south of Mars (Figure 3). Mars will be at mag -1.1, while the Moon will be at mag -12.5. Both objects will be located in the constellation Taurus. The duo will be too far apart for a telescope to see them, but they will still be visible to the unaided eye or via a small telescope .

Jupiter will be visible in the southwestern night sky after sunset. On 26 January, the Moon and Jupiter will be in close proximity, passing just 1°36' apart. But you can see it on the western horizon in the evening after sunset (Figure 4). They won't fit within a telescope's field of vision because they will be too far apart, but they will be visible to the unaided eye or via a pair of binoculars .

Venus and Saturn will lie in the constellation Capricornus and can be observed in the southwestern night sky. On January 23, three (3) conjunctions will take place (Figure 5); these are the conjunction between Saturn and Venus , the conjunction of Saturn and Moon , and the conjunction of Venus and Moon .

The Quadrantid meteor shower, produced by asteroid 2003 EH1 is active from 28 December to 12 January, with peak activity occurring on 04 January. At its peak, Quadrantids is estimated to produce a nominal rate of 110 meteors per hour . The meteor shower is anticipated to be active from the time the constellation Bootes radiant rises in the northeastern sky around 01:00 AM. The presence of a waxing gibbous Moon, which is nearly three (3) days away from its full phase at the shower’s peak, presents significant interference with the meteor shower observation (Figure 6) .
Figure 6. The view of the southeastern sky during the peak of Quadrantids on 04 January at 04:00 AM when the shower's radiant is represented by the green solid circle.
The finest display of meteor shower is visible whenever the shower’s radiant point is above the horizon, with the number of visible meteors increasing as the radiant point ascends higher in the sky. Meteor showers are observable through the naked eye, and no special equipment such as telescopes or binoculars is needed. Maximize the viewing experience by choosing a dark observation site away from the city lights under clear and moonless sky conditions.
The Department of Science and Technology encourages everyone to support the advocacy for the observance of National Time Consciousness Week (NTCW) on 01-07 January 2023. With NTCW 2023 theme “Oras Pinas: Tamang Oras Tungo sa Maunlad na Pilipinas,” the event aims to promote punctuality among Filipinos as it plays a crucial part in building a more progressive nation.
The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA), the designated official timekeeper of the Philippine Standard Time, will be conducting a webinar to help spread awareness of the importance of time in the everyday lives of every Filipino.
