Venus and the Moon

The forecast was predicting heavy cloud cover after dark yesterday, but in the afternoon we had a clear spell. I used this opportunity to capture Venus and the Moon before the occultation. The following was taken at 15:34 UTC, a few minutes before the Moon moved in front of Venus.

As predicted the cloud covered the rest of the occulation.

Close encounter between Venus and the Moon

On Saturday, Venus and the Moon made a pretty close approach, we didn't get it as close in Europe as people did in the Americans, but it was a pretty close encounter nevertheless.

I've got the high resolution (3456x2304) versions of these in the gallery.

Venus

Here's an image of Venus I took on Wednesday evening. This was taken with a 6 inch TAL 2M reflector and a Philips Toucam Pro II webcam. Image is the result of approximately 400 frames.

The Planet Venus

You'll notice it has phases; this was one of the evidences for a Sun centred solar system. If Venus's orbit was outside that of the Earth, yet inside the Sun, you would expect Venus to maintain a very slim crescent. However what we actually see is Venus ranging from being full to an extremely thin crescent.

Venus is an easy object to spot in the western sky after sunset. You won't miss it, its third in brightness only to the Sun and the Moon. As Venus starts overtaking the Earth's orbit it will race closer and closer to the Sun, then in August it will move between the Earth and the Sun, and will over September and October become more visible in the morning skies, until finally going back around the far side of the Sun and re-appearing in the evening sky.

Venus close to the Moon followup

Here's the followup picture from my previous post.

Venus and the Moon

We can use the Sun to help highlight the geography of the Moon, as the Sun slowly rises other the lunar surface light flood into vallerys and crators, or vast shadows are cast by mountain ranges. You can see this on the closeup below, the terminator isn't smooth, its all bumpy, even over the space of a few hours you can often see quite dramatic changes along the terminator as the Sun floods into areas of shadow.

Below you can see quite a prominant feature on the western rim of Mare Crisium, just as the Sun begins to rise over the highground around the sea.

Moon close up

Venus close to the Moon

If you go outside right now (even if its daylight), Venus is a few degrees south of the Moon. That makes Venus possible to spot in daylight assuming you've got really transparent skies. You'll probably need binoculars but its possible.

It also means the Moon is hanging around near Venus in the evening sky, here's a photo I took yesterday.

Venus and the Moon

I've got high-resolution versions and close ups of the Moon on my gallery.

Weather permitting, I'll be taking one again this evening, the Moon would of moved up above Venus. This is because the Moon takes only a month or so to orbit the Earth, so every day it moves about 13° across the sky, the Moon is about half a degree in width which means it moves its own width about every hour compared to background objects. It orbits anti-clockwise when viewed from the north pole and so, compared to everything else in the sky it moves slowly leftward. Keep in mind the Earth's rotation is about 28 times faster, so we only see this movement relative to things behind it, the Moon still rises in the east and sets in the west.
