Of late, I’ve become interested in the subject of astronomy, thanks to my meeting with Dr Chong of Universiti Sains Malaysia’s School of Physics. Dr Chong is an iconic figure in the field of astronomy in Penang, no less the whole of Malaysia. Talk to the man and I’m pretty sure you’ll be interested in what makes the planets and stars go round. If not, at least you’ll know why planets and moons in our solar system are spherically shaped and not squares, triangles etc.
Anyways, there was an annular eclipse that took place last Friday, with the eclipse track starting from countries in Africa, moving across the ocean to southern India, Sri Lanka, then moving across the ocean again to Myanmar and ending in southern China.
This annular eclipse was quite special as it was the longest annular eclipse in the third millennium, lasting some 11 mins and 8 secs (somewhere in the middle of the Indian Ocean). Oh ya, the next longest annual eclipse will be in 3043.
Annular eclipses are different from total ones because for annular eclipses, the moon, while it passes between the earth and sun, does not completely block out the sun’s disc due to moon being further away from the earth as compared to during total solar eclipse. What happens then, during an annular eclipse is that viewers get to see what’s know as the ring of fire.
Unfortunately, I missed the chance to go to China, Myanmar, Sri Lanka or to India to witness this event, so that means I missed the ring of fire. But, Dr Chong and co. still made the best of the situation and we all gathered up on the Queensbay Mall rooftop to catch the partial eclipse that came our way. From where we were, our sun was 23.3% covered by the moon, not enough to cause dimming or cooler temperatures.
The pix will do the talking…

If you notice carefully, the holes where the light passes through are crescent suns!

Check out the rough ridges between the sun and moon. I think the sun light is outlining the surface of the moon…
