The awaited annular solar eclipse, the period when the moon covers the sun’s center to form a “ring of fire” on its outer edges, may not be fully observed in Palawan as expected on December 26 due to mostly cloudy skies, said the local state weather bureau office.

“‘Iyong last 10 days ng Disyembre, based talaga sa ating na-obserbahan ay nagiging mostly cloudy sa mga panahon na ‘yan. Iyan din ang mga panahon na may mga low-pressure systems na dumadaan so hindi natin matitiyak,” said local Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) chief Sonny Pajarilla.

Over Palawan skies on December 26, the partial eclipse is supposed to begin at 12:20 p.m. when the moon touches the sun’s edge, with the maximum eclipse at 2:14 p.m. when the moon is closest to its center and at 3:47 p.m. when the moon leaves the sun’s edge.

“Annular” comes from the Latin word “annulus” which means “ring”. It can last over three hours in locations where the annularity is said to be fully visible. But from start to end, the full duration of the annular eclipses can be more than six hours but not in all locations.

“ Iyong weather natin ay hindi natin natitiyak kung ano ang magiging sitwasyon. Iyong annular ay parang gumuguhit lang ‘yan, halos hindi napapansin iyan. Medyo maulap yan,” Pajarilla said.
