Yesterday, we had a special Sunday evening because it was the first time we watched the occultation of the Venus by the moon.

The Venus (second planet from the Sun) went behind the moon which was in the new moon phase.
Let me show you the whole process with the following photos (although they were taken using my 560mm lense, but they still need to be heavily cropped to show you what has happened).
It was about 7 pm, the sky was not completely dark yet but in dark blue, I was doing some work in the garden. I was a bit tired and stood up and looked towards the west (the direction of sunset to see if the sky was painted in a nice colour). Suddenly, I found that a bright star was just next to the moon. I know it is the Venus, and it reminded me about the news that I read from the newspaper a few days ago where the moon will cover the Venus. I quickly stopped all my garden work, washed my hand and grabbed my camera…

19:23:32 (+08:00GMT): There was still a distance between the moon and the Venus. The sky was completely dark at that time.
From what I have learned about Astronomy, I know that the moon moves slower compared to other astronomy objects in the sky (not her own speed, but when we view it from earth as the earth is rotating and orbiting). Do you know that the moon always rises about 50 minutes late compared to the previous day. The moon was going to set in the next one or two hours, and I was sure that the Venus was going to overtake the moon and set under the horizon earlier than the moon.

19:30:17 (+08:00GMT): The Venus was touching the moon when I looked at them using my naked eyes, but the photo told me it was not.
Although it was only a short period of time, but two minutes would be very long if one has no patience to wait. I keep on waiting for the Venus to disappear, but it was still there.

19:32:27 (+08:00GMT): The Venus was starting to touch the moon.
My brother joined me because I borrowed his tripod. He has a lighter tripod and easier to be setup. The mosquitoes kept on biting us.
Without professional equipment that usually owned by the astronomy photographer, the quality of these photos has limited quality, and I purposely edited and made them over-exposed so that it can show the entire moon disk (which include the dark area of the moon).

19:34:38 (+08:00GMT): The Venus has partially gone into the moon, and this is the last photo before the Venus disappear.
Before that I was shooting in burting mode (4fps) and stopped about every 10 frames for a few seconds, at this time, I switched away the shooting mode to single shoot, and prepared to take a break.
It was now time to move my tripod because the roof of a building was going to block the moon. While waiting for the Venus to come out, I setup my own tripod because it can hold my camera better. I also helped my brother to find a better location to shoot. The tall building next to our house blocked a big piece of sky from us.
My brother shoot video mainly. He has a strange way holding his tripod. He did not extend the legs of the tripod and put the tripod on the ground but he hold the tripod with his hands instead of holding the camera directly, he said this way is still effective.

19:52:31 (+08:00GMT): The Venus was still covered by the moon. We kept on waiting, and got our camera ready.

At about 8 pm, a piece of cloud came from random direction and covered the moon. We kept on waiting hope that the cloud would go away but it did not. We stopped our moon & Venus shooting session when the mosquitoes kept on attacking us.

This was how the surrounding looked like before the sky turned dark.
I hope I can encounter more eclipses, occultation and transits of planets, planet’s satellite and stars. Some of them occur quite frequent, but in a fixed location on Earth, it might happens only in a few thousands years. If you want to know what eclipses, occultation and transits mean in astronomy, you can check them on Wikipedia. :)
According to the newspaper, occultation of Venus by moon will only happen again 20+ years later, but from what I read from here I found that there is 1 to 3 time of Venus occultations each yaer, but most of them are not visible in my location (Kuching, Malaysia).
