Whitsunday Sunset


Whitsunday Sunset #1

This was a perfect sunset for displaying the subtle shades of twilight.

On this evening the sky over the ocean showed off the classic sunset gradient from deep orange though yellow, purple and into deep twilight blue. I shot this on the water on my cruise around the Whitsunday Islands on board the Solway Lass. Note the dark reflections of clouds in the water.

We’re looking west, of course – the Sun still sets in the west in the southern hemisphere! – which is back toward the mainland of Queensland, Australia.

Island Moon At Sunset


Moon Over Baur Bay, Whitsundays

One of the great joys of sailing and being out on the water is the wonderful sunsets. In this case, sunset included a fine moonrise.

This is the gibbous Moon of November 26 in the evening sky over the Whitsunday Islands in Australia. On this evening we were moored in Baur Bay, at South Molle Island. The bright waxing Moon shines amid the red clouds in the east still lit by the last rays of the setting Sun from the west. It is everyday scenes like this, painted with the wonderful palette of colours only the sky can provide, that you begin to appreciate all the more – or more to the point, simply see – as you become “sky aware.” So no great science lessons to learn here – just some beautiful colours to soothe the soul as gentle waves lap against the side of the ship.

Sailing Toward Orion


Sailing Toward Orion

Not so long ago sailors used the Moon, Jupiter and the stars to chart their course on Earth. All are in this moonlit seascape.

I took this shot on November 27, as we set sail toward Hook Passage in the Whitsunday Islands, Queensland, Australia. The ship is the Solway Lass, a 110-year-old sailing ship that is now the oldest commercial ship plying the waters around Australia. It has been modernized and refitted, and at night runs with engines, not sails. And today, of course, GPS keeps the skipper informed of where the ship is. But before GPS and radio navigation, sailors used the sky to determine where on Earth they were.

Sextant sightings of the Sun and stars could give them their latitude and longitude. One star often used was Canopus, visible at far right in this image. Canopus has long been associated with the sea. It is the brightest star in Carina the Keel, once part of the sprawling constellation Argo Navis, the ship in the Greek legend of Jason and the Argonauts. Today, Canopus is still sighted by robot spacecraft bound for the planets to help them determine their position in the solar system.

Sirius and the stars of Orion (lying on his side here at a latitude of 20° South) appear through the rigging. At upper left is the bright glow of the nearly Full Moon, near the star Aldebaran and the Hyades star cluster.

Before the acceptance in the late 1700s of the chronometer as an accurate time-keeping device, the position of the Moon near bright stars served as an astronomical clock in the sky to provide sailors with local time. Another source of time (more for land-based navigators) was the changing positions of the moons of Jupiter — Jupiter is the bright star-like object at left.

I just finished a superb 6 days of sailing around the Whitsundays and will have 2 or 3 more sea-bound posts from this wonderful area of the world.
