Annular Solar Eclipse January 15, 2010 [Partial Solar Eclipse in Bangalore and all parts of Karnataka]

After waiting for more than three decades, this month we have a chance to observe the Annular Eclipse. On January 15th, 2010 we will be able to watch the ASE from many cities in South India. Karnataka will witness the Eclipse as Partial Solar Eclipse, ABAA members will be visiting Rameshwaram which is very close to the central line to observe the event and photograph the Annular Solar Eclipse.

We all know that Annular eclipse takes place when the angular diameter of the Moon is less than that of the Sun.

We will examine the conditions of the Sun and Moon for this Eclipse.

On January 3rd Sun will be closest to Earth with approximate distance of 14,71,01,455 km and on 15th of January the Sun will have a distance of 14,71,53,269.484 km. Using the distance and diameter we can find out the angular size of the object. Distance of Sun we already know and the diameter of Sun is 1,392,000km, dividing diameter by distance and multiplying the result with 57.3 we get angular size of the Sun.

Angular size = (diameter / distance ) * 57.3

on 15th Sun will be at 14,71,53,269.484 km

the Angular size of Sun = (1,392,000/ 14,71,53,269.484) * 57.3

= 0.542 degrees

Applying the same for Moon

Diameter of Moon is 3474km and distance of Moon on 15th is 4,04,714km. Moon will be farthest from Earth on January 17th.

Angular size = (diameter / distance ) * 57.3

= (3474 / 4,04,714) * 57.3

= 0.4918 degrees

As we can see Moon's angular diameter is much smaller than that of the Sun, this results in Annular Eclipse.

Details for Bangalore(January 15, 2010 the Annular Solar Eclipse will be visible as a Partial Solar Eclipse in Bangalore, Karnataka and rest of India):
