Mercury Appears in the Dawn

The planet Mercury is starting a morning apparition. The planet should become visible this week just above the dawn as a magnitude -1 object. The planet is moving more than 1° further from the Sun and higher in the morning sky each day, reaching a maximum elongation of 18° on October 15th.

Mercury Appears in the Evening Sky

The planet Mercury is starting an evening apparition. The planet should become visible this week just above the fading glow of the setting Sun as a magnitude -1 object. The planet is moving about 1° further from the Sun and higher in the sunset each day, reaching a maximum elongation of 27° on September 4th. This will be the best evening apparition for Mercury in 2015.

The Sky for 2014

What is happening in the sky this year?

There are no exceptional sky events expected in 2014. A pair of good lunar eclipses, a decent Mars opposition, the usual meteor showers, and no bright comets predicted. There is one odd meteor shower that might provide some fireworks in May mentioned below. Otherwise there is always the possibility of a new discovery, a nova or supernova, or a new comet. For now this looks to be a routine year for sky watchers.

Planets

Venus is as always a fun planet to follow through the year. The brilliant morning or evening star is always notable when it passes other bright objects such as the Moon or Jupiter. In April and May Venus will pass both ice giants, Uranus and Neptune with under a degree of separation. In August it will be Jupiter, passing about 35′ away on August 14th. The approach will be even closer if you are able to observe the pair during daylight hours, closing to 12′ at 08:06HST on the 14th.

Mars will pass through opposition on April 8th this year. This is a relatively good viewing opportunity with the red planet appearing just over 15″ in size. Close approach will be a week later, on April 14th. On September 27th Mars will pass about 3° from Antares.

Jupiter and Saturn continue to be well separated in the sky. This results in one or the other being available for observation much of the year. We start with Jupiter in the evening sky until early July. Saturn is currently in the early morning sky, passing through opposition May 10th and available for observation in the evening sky for the latter half of the year.

Minor Planets

The minor planets Ceres and Vesta are quite close all year. So close they will experience opposition in the same week. The dance will take place with the constellation Virgo as the backdrop. 4 Vesta will pass through opposition on April 13th, only two days later 1 Ceres will do the same on the 15th. At the same time the planet Mars will be just a few degrees south of the pair, going through opposition on April 8th. I wonder if the astrologers have noticed this? If so I am sure they will attach some ridiculous speculations to the event. They do not usually pay attention to the minor planets.

Lunar Eclipse 28Aug2007

Eclipses

There are two solar eclipses and two lunar eclipses for 2014. An odd annular solar eclipse will be visible from Antarctica and Australia on April 29th. A deep partial solar eclipse will be visible across much of western North America on October 23rd. Neither will be visible from the islands.

The two lunar eclipses are more interesting. Both total eclipses will feature good magnitudes and the eclipses will both be visible in their entirety from Hawai’i. Better yet, the first eclipse will begin soon after sunset, providing an excellent viewing opportunity for outreach. Occurring on April 14th and October 7th, these will be the highlight of the year for eclipse aficionados.

Meteor Showers

2014 offers an interesting year for meteor watchers. Of the three most reliable showers it is the Quadrantids that will be seen to best effect in 2014, untroubled by moonlight. The Geminids will be partly obscured, while the Perseids will peak quite close to full Moon.

In addition to the traditional showers there are predictions for a new shower associated with Comet 209P LINEAR. In late May this debris stream may produce a strong, or even storm level meteor shower. Watch here for more information on this possible event.

Comets

While no spectacular comets are predicted for 2014 there are several decent comets available for telescopic observing or photography. Late summer and into early autumn look for comet C/2012 K1 PanSTARRS to peak around magnitude 6.

As usual you should keep tuned to Darker View for timely reminders of upcoming celestial events. Over a hundred posts are already entered and waiting for the appropriate date to pop up here, reminding you and I to keep looking up.

Seeing Venus in the Daytime

It is possible to see planets in the daytime. Both Jupiter and Venus are bright enough to see fairly easily in full daylight if conditions are right. You need to know where and how to look, but once glimpsed they are fairly easily seen. It is the knowing how that makes it possible. Try these simple hints…

  • Try when the planets are far from the glare of the Sun, in the first hours after dawn or last hours of the day are best.
  • Clean air is necessary. If the air is hazy, dusty or smoggy it will hide the planets from view, particularly when near the Sun. There will just be too much solar glare to pick out the planet. For the same reason try when the planet is high in the sky and you are looking through much less air.
  • The human eye will relax and defocus if there is nothing to focus on. This happens when looking at a plain expanse of blue sky. You could be looking right at the planet and not see it. A few puffy clouds around, or better yet, the Moon, will give the eye something to focus on, allowing the planet to be easily seen.
  • Put the Sun out of sight to reduce glare. Simply position yourself in the shadow of a tree or building to get a better view.
  • Pick a day when the Moon is near the object you are looking for, it will provide a simple signpost to the correct location.

It is this last hint that can be particularly useful today. Venus is about 8° degrees south of the Moon today. It helps that Venus is near maximum elongation, as far as it will get from the Sun for this evening apparition. If you can find the Moon high in the midday sky check just below it for Venus. The planet will be about a sixteen lunar diameters away from the Moon, seen as a bright star-like object.

Have a try.

Violent Events in Rocky Planetary Systems: Implications for the fate of technological civilizations

Gates Performing Arts Center Auditorium
Hawaii Preparatory Academy

This evening, Dr. Ben Zuckerman of UCLA, will take us on a journey describing Earth’s formation 4.6 billion years ago to its possible demise 4-5 billion years from now. Along the way, we will consider a few tumultuous eras suffered by Earth’s biosphere, including the present. Such eras, from origins to final resting places, can be explored by understanding astronomical studies of other planetary systems. These systems also provide clues for the long-term fate of our technological civilization and the likelihood, or lack thereof, of civilizations beyond our own.

Seating is limited to first come, first served.
