About a month ago I was walking home and my eye caught something on the sidewalk. Backtracking I recognized it as a cicada. Backtracking again I thought to pick it up if it were dead, which it was. I have finally gotten around to photographing it and processing the images. They aren't great, but do illustrate the insect.

This is the business side of the insect.

From the description of the sound-making apparatus I think this is it although I can't figure out its mechanics.

The giveaway for people finding these things is the eyes, which are huge.

The insect has a large proboscus that, according to the literature, is about as dangerous to humans as that of a butterfly.

When I woke up the other day I heard a few cicads calling so stuck a microphone out the window and recorded( 1.14 MB MP3 file) them (and a lot of the other noise I have to listen to when my windows are open).

I was on my way home to dinner and saw Jupiter so decided to walk around the oval seeing what else might be there. Then I remembered that I had my binocular in my bag so got it out and walked around again.

Target Jupiter Constellation Sgr Category Planet Time yyyymmdd.hhmm 20080821.2100 EDT Comments Jupiter was low over the apartment buildings directly across from me and looked huge and very bright. With the binocular I thought I saw a moon on the eastern limb (it would have been Europa) but it is hard to hold the small binocular still to view close objects.

20 August 2008

A found several definitions in Ambrose Bierce's The Devil's Dictionary that relate to astronomy and related sciences.

Berenice's Hair

n. A constellation (Coma Berenices) named in honor of one who sacrificed her hair to save her husband.

Her locks an ancient lady gave
Her loving husband's life to save;
And men -- they honored so the dame --
Upon some stars bestowed her name.

But to our modern married fair,
Who'd give their lords to save their hair,
No stellar recognition's given.
There are not stars enough in heaven.

Day

n. A period of twenty-four hours, most misspent. This period is divided into two parts, the day proper and the night, or day improper – the former devoted to sins of business, the later consecrated to the other sort. These two kinds of social activity overlap.

Lunarian

n. An inhabitant of the moon, as distinguished from Lunatic, one whom the moon inhabits. The Lunarians have been described by Lunican, Locke and other observers, but without much agreement. For example, Bragellos avers their anatomical identity with Man, but Professor Newcomb says they are more like the hill tribes of Vermont.

Magnitude

n. Size. Magnitude, being purely relative, nothing is large and nothing small. If everything in the universe were increased in bulk one thousand diameters nothing would be any larger than it would be larger that they had been. To an understanding familiar with the relativity of magnitude and distance the spaces and masses of the astronomer would be no more impressive than those of the microscopist. For anything we know to the contrary, the visible universe may be a small part of an atom, with its component ions, floating in the life-fluid (luminiferous ether) of some animal. Possibly the wee creatures peopling the corpuscles of our own blood are overcome with the proper emotion when contemplating the unthinkable distance from one of these to another.

Molecule

n. The ultimate, indivisible unit of matter. It is distinguished from the corpuscle, also the ultimate, indivisible unit of matter, by a closer resemblance to the atom, also the ultimate, indivisible unit of matter. Three great scientific theories of the structure of the universe are the molecular, the corpuscular and the atomic. A fourth affirms, with Haeckel, the condensation of precipitation of matter from either – whose existence is proved by the condensation of precipitation. The present trend of scientific thought is toward the theory of ions. The ion differs from the molecule, the corpuscule and the atom in that it is an ion. A fifth theory is held by idiots, but it is doubtful if they know any more about the matter than the others.

Newtonian

adj. Pertaining to a philosophy of the universe, invented by Newton, who discovered that an apple will fall to the ground, but was unable to say why. His successors and disciples have advanced so far as to be able to say when.

Observatory

n. A place where astronomers conjecture away the guesses of their predecessors.

Past

n. That part of Eternity with some small fraction of which we have a slight and regrettable acquaintance. A moving line called the Present parts it from an imaginary period known as the Future. These two grand divisions of Eternity, of which the one is continually effacing the other, are entirely unlike. The one is dark with sorrow and disappointment, the other, bright with prosperity and joy. The Past is the region of sobs, the Future is the realm of song. In one crouches Memory, clad in sackcloth and ashes, mumbling penitential prayer; in the sunshine of the other Hope flies with a free wing, beckoning to temples of success and bowers of ease. Yet the Past is the Future of yesterday, the Future is the Past of tomorrow. They are one – the knowledge and the dream.

Telescope

n. A device having a relation to the eye similar to that of the telephone to the ear, enabling distant objects to plague us with a multitude of needless details. Lucky it is unprovided with a bell summoning us to the sacrifice.

Year

n. A period of three hundred and sixty-five disappointments.

Yesterday

n. The ifancy of youth, the youth of manhood, the entire past of age.

But yesterday I should have thought me blest
    To stand high-pinnacled upon the peak
    Of middle life and look adown the bleak
And unfamiliar foreslope to the West.
Where solemn shadows all the land invest
    And silly voices, half-remembered, speak
    Unfinished prophecy, and witch-fires freak
The haunted twilight of the Dark of Rest.
Yea, yesterday my soul was all aflame
    To stay the shadow on the dial’s face
At manhood’s noonmark! Now, in God His name
    I chide aloud the little interspace
Disparting me from Certitude, and fain
Would know the dream and vision ne’er again.

Baruch Arnegriff

Zenith

n. A point in the heavens directly overhead to a standing man or a growing cabbage. A man in bed or in a cabbage in the pot is not considered as having a zenith, though from this view of the matter there was once a considerable dissent among the learned, some holding that the posture of the body was immaterial. These were called Horizontalists heresy was finally extinguished by Xanobus, the philosopher-king of Abara, a zealous Verticalist. Entering an assembly of philosophers who were debating the matter, he cast a several human head at the feet of his opponents and asked them to determine its zenith, explaining that its body was hanging by the heels outside. Observing that it was the head of their leader, the Horizontalists hastened to profess themselves converted to whatever opinion the Crown might be pleased to hold, and Horizontalism took its place among fides defuncti.

Zeus

n. The chief of Grecian gods, abored by the Romans as Jupiter and by the modern Americans as God, God, Mob and Dog. Some explorers who have touched upon the shores of America, and one who professes to have penetrated a considerable distance into the interior, have thought that these four names stand for as many distinct deities, but in his monumental work of Surviving Faiths, Frumpp insists that the natives are monotheists, each having no other god than himself, whom he worships under many sacred names.

SpaceWeather has a brief article today about how observers in Norway detected the passage of a solar wind gust on 18Aug08 UTC by watching the earth’s magnetic flux. I have built a solar wind indicator that would do this but have never gotten it completed to the point that I have tested it and wasn’t looking at it at the time the gust passed by.

I am reading Ambrose Bierce's The Devil's Dictionary and found an entry that I think could be applied to the Pluto debacle:

Australia

n. A country lying in the South Sea, whose industrial and commercial development has been unspeakably retarded by an unfortunate dispute among geographers as to whether it is a continent or an island.

NASA has announced a delay in the launch of the Lunar Reconnaissance Orbiter from Dec08 until Feb09.

The delay does not seem to be a necessity and is going to cost NASA $7 million a month ($21 million total) which will come out of a slush fund built into the LRO program budget. (If the agency is canceling missions to get up to "the Moon and beyond", why is there a $21 million slush fund in the LRO budget and how many other budgets have similar slush funds that could be transferred back to other programs?)

DoD will be taking over the launch window and rocket to test a reusable satellite. There is no indication that there is any urgency in launching that craft early, but DoD wouldn't be advertising it if there were. But the launch will get the satellite up there while King George is still on his thrown so we might be going somewhere else before the end of the year.

Spaceflight Now has an article saying NASA has decided not to change the date of the HST Servicing Mission and STS-125.

Atlantis is scheduled to beging the mission on 8Oct08 at 0134 EDT.

Endeavour should liftoff at 2128 EST on 10Nov08.

I don't think there will be a chance to see Atlantis as it passes past NYC on liftoff but Endeavour should be visible at 2136 EST.

It looks like the only reason why they were talking about moving the two launches forward by three or six days was to give them more slosh to get the two flights off the ground in 2008.

Endeavour will be on a launch pad ready for launch in case there is a problem with Atlantis that requires a rescue mission. If they decide that Atlantis is in good shape Endeavour will have its payload installed to ready it for its primary mission in November.

STS-126 still doesn't have a logo. I am assuming that the potential rescue commander and pilot will be the STS-126 commander and pilot so that should be locked down. I don't know if they haven't decided who the mission specialists will be and that may be what is delaying the logo.

Another Spaceflight Now article posted yesterday says that there is another debate on whether Pluto is a planet.

It looks like this is more entertainment and maybe a moneymaker for somebody than anything that is going to change anything.

Mark Sykes of the Planetary Science Institute, who wants all the classical planets and dwarf planets to be real planets, will be debating the classification system with Neil deGrasse Tyson from the American Museum of Natural History, who has long held that Pluto is not a planet.

This diagram does a fairly good job of illustrating the current classification system. The one thing it doesn't address it the new class of plutoids

I think I should have seen the pass but didn’t.     Starts Max. Alt.

The flag is extended a good part of the time and I can see and hear plastic that was protecting a corner of a building that is being pointed flapping in the wind. Clouds are covering most of the sky but there are some gaps out to the NE. The transparency is good where you can see the sky – I can see the right side of the ice cream cone of Boötes. The air feels much dryer than the 56% relative humidity that is being reported. Transparency Good/Poor Seeing

It was surprisingly bright in a twilight sky and I think the CalSky brightness estimate is closer to the fact than that of Heavens Above.

By 2115 it was windy enough that I couldn’t read any longer for fear of the wind doing damage to the pages of my bool.

Atmospheric Conditions	Cloud Cover Broken Clouds becoming Overcast Temperature 74° F Wind Gentle Breeze gusting to Moderate Breeze Humidity Moderate Barometric Pressure 29.88" Hg Rising Feels Like Mild - Cool The wind is blowing plastic liners out of the wire mesh trash cans. Trash is blowing up and down the sidewalk. By 2300 it was overcast and I could no longer locate Jupiter. There was a tiny dark spot over where the flare should occur so I stuck it out in case I got extremely lucky and the clouds broke up or the flare occurred in the small clear patch of sky.

It headed up toward Arcturus and, to the naked eye, appeared to occult the star. It faded from view about 10° to the upper left of Arcturus. This is another one that there is an appreciable difference in the magnitude estimates of Heavens Above and CalSky.

I found my Pupil Gauge today so decided to find out how big my pupils are. During the daytime in my apartment they measured about 3.25 mm. At night outside they were 5.25 mm and when I got home and tested them in my darkened apartment they were ou to 5.75 mm.

I found a link on the web indicating that my pupil should, based on my age, be between 5 mm and 4.1 mm, probably closer to 4.1 mm.

I searched my blog for "pupil gauge" to see if there has been any change from when I got the gauge but don't find any listings so don't know how my eyes have changed over time. But I do know that my arms have shrunk again.
