A Full Night at Kaʻohe
A last star party of the year, actually the last star party of the decade.
With new Moon in the middle of Christmas week I had the choice of the weekend before Christmas, or the weekend after. Guessing that attendance would be better in the quiet days between holidays I chose December 28th as our monthly new Moon star party.
The site was, as usual our Ka’ohe observing site on the side of Mauna Kea. The weather was nearly ideal, clear, not very cold, and almost no wind at the site.
Arriving at the site to find beautiful, clear skies we marveled at the sunset scene. A brilliant Venus and three day old crescent Moon hung above the fading sunset and Hualālai.

Today Jupiter passes through superior conjunction, rounding the far side of the Sun as seen from our earthbound vantage point.
Jupiter will re-emerge in the dawn sky towards the end of the January. Look for the planet low in the glow of dawn, rising higher each day.
Jupiter will pass through opposition on July 13th, 2020, crossing into the evening sky.
New Moon
New Moon will occur today at 19:13HST.
An annular solar eclipse will sweep across the Indian Ocean, Southern India, and Indonesia during this new Moon.
This coming weekend, Dec 29th, offers an excellent dark night for observing. Get out to enjoy some holiday stars!
Continue reading “New Moon”Winter Solstice
The winter solstice will occur at 18:19HST today.
The Sun has reached the most southerly declination it will achieve this year. After today the Sun begins to move north in our skies.
Today will be the shortest day of the year for those of us located in the northern hemisphere.
Today is considered the start of winter for most cultures in the northern hemisphere, or the start of summer for those in the southern hemisphere.

December Observing List
Our next club dark sky star party will be Dec 28th at the usual Kaʻohe site, in the lull between the Christmas and New Year’s holidays.
For the evening I have again assembled an observing list for those who want to explore some of the more interesting objects available in the sky this month.
These are all visible in the early evening, all suitable for average telescopes, with a couple more suitable for binocular viewing.
While most of these will be easy to locate and observe, there are a few more challenging objects in the list.

Full Moon will occur today at 19:12HST.
This evening look for the Moon rising in the east just as the Sun sets in the west. Across the Big Island this can often lead to moonbows as the low elevation moonlight interacts with fog and clouds.

The wall building project is now well along, with sections of completed wall and the outline what it will look like when I am done now apparent.
At this point there is 18 ft of completed wall, another 52 lineal feet of various height walls in various stages of completion from first course laid to nearly topped out. Another 11 feet will be started shortly to complete the first phase of wall building.
To create this much wall over five tons of rock has been loaded, driven 19 miles, unloaded, and hauled to the back yard. Twelve wheelbarrow loads per ton. About 70% of that rock has been stacked into the walls, the remainder in piles awaiting use.
