Sunset, Contrail and the Thin Moon

I and my friend Bea Banzuela were walking around the Academic Oval of our university last May 5 when we noticed the sunset behind the trees at the lawn.

The transition of the bluish sky into crimson during this time of the day is always lovely to look at.

Reeds!
PHOTO OP! That’s me posing in front of the setting sun 🙂 Haha!

I remembered that the 2-day old thin Moon will set just before the Sun that afternoon. I checked Stellarium for its location in the western sky and waited until it became visible.

We soon found it hanging below a contrail a few minutes after the Sun had disappeared from view. It was around 5% illuminated and barely visible to the naked eye.

Luna appears against the crimson-colored sky. Click on the image to see the hi-res version.

As the sky grew darker, the Moon become more apparent, along with the bright stars located around it.

A stunning sight! The Moon with its 'ashen glow' (or earthshine) beside Aldebaran

Staring at the beauty of the night sky

We were grateful that we had along with us a nice point-and-shoot Panasonic Lumix DMC camera which works great when used for landscape photography. Using its starry sky mode, we were able to produce the images above even with minimal light. This setting allows for 15, 30 and 60 second exposures that is best for night sky photography. Other cameras often produce very dark images unless there is some amount of light out. (Thanks to Aaron Misayah for lending us his camera.)

I hope the sky would always be this clear. 🙂

Skywatching Highlights: May 2011

From PAGASA:

The month of May will show up the finest planetary conjunctions of the year. Naked-eye planets line-up in the eastern horizon before sunrise. On May 1, 9, 13, and 30 at 5:00 AM, Mars, Jupiter, Mercury, Venus, Uranus and Neptune will be found lining-up above the eastern horizon as shown in Figures 2, 3, 4, and 5  respectively. Uranus and Neptune will be needing a star map and a binocular or a modest-sized telescope for its proper viewing. The planets will lie among the background stars of the constellation Pisces, the Fish, except for Neptune, which will be found at the constellation of Aquarius, the Water-Bearer.

Saturn will be visible in the evening sky throughout the month. The Ringed planet will be located among the background stars of the constellation Virgo, the Virgin.
