Full Moon occurs on the 5th at 11:35 pm Eastern Daylight Time. May’s Full Moon has a number of popular names, among which are the Milk Moon, Flower Moon, Corn Planting Moon, and Hare Moon. This particular Full Moon occurs one minute after lunar perigee, and since perigee coincides with a Sun/Earth/Moon syzygy it is the closest perigee for the year. Luna will be 356,955 kilometers (221,801 miles) from Earth’s center at the time. Popular media have recently dubbed such a phenomenon as a "supermoon", since Luna is about 14% larger in apparent diameter and therefore brighter than a "regular" Full Moon.

Happy First Day of Summer

Those great days from May Day to Lammas.

The Sky This Week, 2012 May 1 – 8 — Naval Oceanography Portal

May 1st is one of the four so-called "cross-quarter" days that hearken back to traditional calendars of medieval times. These days, along with the seasonal markers of solstices and equinoxes, were the traditional days when serfs paid rent to their feudal masters. Most of these "mid-season" dates are now forgotten, but we still unwittingly observe them in various cultures. Americans are quite familiar with Halloween and Groundhog Day, but May 1st isn’t widely observed on our side of the Atlantic Ocean. However, May Day is still widely celebrated in Europe, especially in countries with a strong Celtic tradition. The fourth cross-quarter day, Lammas, falls around August 1st and is probably the least observed of these traditional times. You can think of May Day as the middle of spring or as the beginning of summer. Either way we are now in the time when the length of daylight exceeds 14 hours, which it will do until early August.

Some great photos here.

Earth Day 2012 – The Big Picture – Boston.com

April 22 will mark Earth Day worldwide, an event now in its 42nd year and observed in 175 countries. The original grass-roots environmental action helped spur the Clean Water Act and Clean Air Act in the United States. Gathered here are images of our planet’s environment, efforts to utilize renewable alternative sources of energy, and the effects of different forms of pollution. — Lane Turner and Leanne Burden Seidel (35 photos total)

"Public Is Behind Wolves; Will Government Get the Message?"

I wish I still felt this way. Unfortunately, the people who hate wolves hate the government. While we politely rally for the wolves, the haters have them in their gunsights — quite literally. Sometimes rebels are merely criminals and thugs who bathe themselves in blood.

ABQJournal Online » Public Is Behind Wolves; Will Government Get the Message? by Billie Hughes

Fourteen years after those initial reintroductions, the wolves continue to struggle, however. It is not because they are not doing their part. They are forming packs – family units – breeding, raising young and killing elk and deer. They are fulfilling their role in the ecosystem. We need to fulfill our role as stewards, as people with a responsibility to these animals, their ecosystem, and to future generations of Americans. We must ensure that these animals have a chance and that our children can hear their howls decades from now. There is strong support from the public for that. Now we need our government at all levels to get that message.

Let the mean-spirited wicked bastards win

I no longer support efforts to restore the lobo to its rightful habitat in the wildlands of New Mexico. Yes, the blood-thirsty, cold-hearted sons-of-bitches can have their way, just like well-armed babies. Yes, the late-comers who claim they own all public lands can deny the majority its will. Yes, a small number of cowardly dimwits can determine the fate of the ecosystem.

Now and then, ugly, stupid, mean, and wrong triumph. I’m tired of the slaughter of decent animals by indecent ones.

“We’ll have to wait quite a while before we see as dazzling a gathering of planets in the western twilight sky”—2036!

The Sky This Week, 2012 March 27 – April 3 — Naval Oceanography Portal

We’ll have to wait quite a while before we see as dazzling a gathering of planets in the western twilight sky as we have seen for the past few months. Now that Venus has left Jupiter in her wake the duo seem to go their separate ways, and their next close conjunction at such a prominent altitude in the evening sky won’t occur until the year 2036. However, early risers in the midsummer months will have a chance to enjoy the pair in close proximity in the morning sky for several weeks in late June and July before they ultimately part company. They will meet about once each year, either before dawn of after sunset, between now and 2036, but most of these encounters will occur in twilight within 15 degrees of the horizon. Favorable evening elongations of Venus, similar to the one she’s undergoing now, occur at eight year intervals, while Jupiter takes about 12 years to go once around the sky. Thus every third favorable elongation of Venus occurs when Jupiter has completed two orbits, and a dramatic conjunction occurs high in the post-twilight sky. Yes, the end of March 2036 should be quite spectacular, with Mercury, Venus, Mars, Jupiter and the Moon all visible in the western sky for your entertainment. Better mark those calendars now!

An odd way to measure space …

From the Albuquerque Journal sky watch:

The “box” of Orion covers about 130 square degrees. The bowl of the Big Dipper holds about 45 square degrees. Crux, the Southern Cross, covers an area of only about 12 square degrees. But what is the area, in square degrees of the entire night sky? 41,253 square degrees.

This implies a set distance out from the surface of the globe to calc – come in closer, fewer square degrees, go out farther, more square degrees – spheres inside of spheres inside of spheres, which one do they pick? Should be able to calc the radius from the formula for the surface of a sphere (strictly, inner surface, but same calculation).

Venus and Jupiter 3 degrees apart near sunset

 

Cold and Spellbinding: An Alignment of Planets in the Sunset Sky – NASA Science

In March, Venus and Jupiter continue their relentless convergence until, on March 12th and 13th, the duo lie only three degrees apart—a spectacular double beacon in the sunset sky (sky map).  Now you’ll be able to hide them together behind a pair of outstretched fingertips. 

There’s something mesmerizing about stars and planets bunched together in this way—and, no, you’re not imagining things when it happens to you.  The phenomenon is based on the anatomy of the human eye. [mjh: worth reading the rest at the link]

Roughly three minutes more of daylight every day

The Sky This Week, 2012 March 6-13 — Naval Oceanography Portal

One of the reasons we change our clocks is that this time of the year we experience the most rapid changes in the times of sunrise and sunset. As we approach the equinox we gain about three minutes of daylight per day. During the course of the week sunrise will arrive 10 minutes earlier and sunset will occur 8 minutes later. We now experience some two hours more daylight than we did just three months ago. Spring is definitely almost here! …

The present rules were amended by the Energy Policy Act of 2005. We’ll stay on Daylight Time until the first Sunday in November, which falls this year on the 4th.
