First light of ATM workshop telescope

It was a nice evening at ABAA on Sunday 19th, as the first telescope of this year's ATM workshop saw the first light. The 6 inch telescope mirror was ground and polished by ATM workshop participant Amrutha. The skies were pretty decent, as shiva prasad described it, with very little haze. Later the haze also cleared. The First object the telescope observed was Moon, in gibbous stage. Members and ATM participants enjoyed observing moon's surface and few photos were taken, thanks to Anita and her iPhone 3GS.

Next was the giant planet Jupiter. Witnessing the transit of IO on the surface of Jupiter and wonderful sight of emergence of IO was a good experience.

Congratulations to Amrutha for completing the telescope. In coming couple of Sundays all the telescope will see the first light.

Mercury greatest Western elongation

On Sunday 19th, the planet Mercury will reach Greatest Western elongation. It is called Western elongation because the planet will be west of Sun, although we will be seeing the planet in Eastern horizon. Maximum angular separation of Mercury from the Sun will be 18degrees. As Mercury will be low in the horizon, clear horizon is essential. Mercury will rise at 5am and will reach little comfortable viewing altitude of 12 degrees at 5:50am.

Sun will rise at 6:08am on Sunday.

Jupiter will reach opposition on September 21^st , this means, the planet Jupiter, Earth and the Sun will be the straight line. As a result, Jupiter will rise as the Sun sets, giving observers chance to study the planet all night.
