One Last Weather Post

With the forecast steady for partly cloudy days and evening fog followed by weekend showers, I will make this the last lament about missed sun, moon and bridge observations.
The shot above is from last night just before sunset, framed in that dim pink swath just above the water is the Golden Gate Bridge, trust me. The shot below is from about fifteen minutes later the very faint line across the sun is one of the cables from the bridge. Yes to the naked eye and the binocular assisted view it was a very nice image.

Next post, I shall return to those thrilling days of yesteryear when I blather on about whatever comes to mind, heart, soul or spleen.

Oh and the moonrise was brilliant last night, I was out in North Berkeley and got a perfect view of the gibbous moon slipping in and out of the high clouds but that was far to the east, by the time the moon had swung across the sky to my windowed western view, twas nary a shimmer behind the grey.

In veils of deepening gloom
As fantasy strides over colourful skies
The fog disappearing from view

If the Sun Sets in the Darkness . . .

This is the view from my window this morning, which provides you with all the information you need about the moonset early this morning. Unfortunately the weather predictors are not encouraging about our chances for more celestial dazzlement this week. The much anticipated full moon settling over San Francisco will occur this Friday and Saturday, which as you can see below is not apparently going to be prime viewer weather.

The first sunset through the Golden Gate narrows happened yesterday, you will not notice in my shot below any sort of bridge or the golden opening to the Pacific. A near fifty mile long fog bank crept in during the late afternoon yesterday to fill San Francisco Bay from end to end.


I would mention one final time that I really am fond of this type of weather. The rain and fog are fascinating for me, my spirits are lifting by the damp and chilled weather, it's like be wrapped in a cocoon the size of the universe. Sounds are muffled, perceptions shrink and we are forced to go on internal sensors. Perhaps in the next few days we will get a glimpse of the astronomical workings between the clouds, if not, I shall attempt to entertain and minister from the internal microcosm.

Pinprick holes in a colourless sky
Let insipid figures of light pass by
The mighty light of ten thousand suns
Challenges infinity and is soon gone
Night time, to some a brief interlude
To others the fear of solitude

Brave Helios, wake up your steeds
Bring the warmth the countryside needs

A Little Lunar Physics

With my celestial gazing blotted out by the grey weather again last night, I turn to a bit of chat about astronomical angles with some solar/lunar synchronicity tossed in for leavening. As I am sure most of you know, but may not often contemplate, the moon has no light of its own. Earth's satellite is a reflective surface, what we see as the illuminated moon is completely solar energy cast back at us.

So when we see or don't see the new moon, it is because the moon is between the earth and the sun. All the light of the sun is on the far side of the moon, which contrary to what Pink Floyd is thought to have said, is not the dark side of the moon at all. At the other apex of earth/sun/moon alignment, a full moon occurs when the earth is between the sun and the moon with the full illumination of the sun on the earth facing moon countenance. The graphic below illustrates these facts of celestial physics. 

When the earth lines up exactly between the sun and the moon, we get a lunar eclipse and I would be remise if I did not remind you that this year on the winter solstice (Dec. 21st) there will be a total lunar eclipse visible in most of North America.

There is no dark side of the moon really. Matter of fact it's all dark.

Whether San Francisco Weather

Robert Burns

After several autumnal heat waves, true fall weather has arrived here in the Bay area. With the lowering to shivering temperatures comes overcast, undercast, fog banks and assorted sky-sea phenomenon. All of these have combined to make my celestial observations more or less muted the last forty-eight hours. The sun has set into high stacks of clouds the last two evenings, the moonset on Friday was an hour early into a high fog bank and last night there was nary a glow from behind the overcast. Today we awoke to grey with a smattering of gray. I was worried that the full moonset next weekend would be blotted out by the dawn but unless we have another change in weather patterns I will miss this highly anticipated week of solar and lunar settings altogether.

I did manage one shot of the setting sun just north of the golden gate narrows last night, you can clearly make out the Golden Gate Bridge. Hope that was not the last sunset this week.

With these eyes before

That's Not the Moon

Last night marked the fifth night of close observation of the moon setting into or over San Francisco. One night was done without the aid of my powerful binoculars, I was out and the tripod would have seemed a bit intrusive. Last night was the closest we would get to a perfect quarter moon, it was officially and exactly quartered around 14:30 in the afternoon and our setting time last night over the City was 0:23.

I am a bit disappointed that I have not been able to successfully google pictures that do justice to the visuals I have seen. And I mourn one last time my own shortcomings in the telephoto/nocturnal camera arena. As always I will attempt to paint you a worthy image in words.

I also want to acknowledge my own, previously overlooked, lack of learning in the general area of astronomy. Each and every night I discover another phenomenon that sends me off asurfin' to uncover the physics of the heavens. I won't overburden you with each and every mote of new learning I uncover. I assume some of you know a lot more in this area than I do and many more of you do not want to wade through the formula, azimuths and ephemeris to "know" why the sky is just amazingly fascinating. 

As I said last night was a near perfect quarter moon but the previous evening (also fairly close to a quarter) I could clearly see the other facing quarter of the sphere. Instead of being slightly lighter than the dark sky, last night the dark quarter of the moon was precisely the same pitch as the sky. This meant the moon presented itself as a jagged edged illusion, as if the top half of the moon was not actually there, like the photo above. And while I watched the descent the oranging began. First the white slice became slightly dirty, then a few minutes later a perfectly hued hard taco shell loomed over the Transamerica building. Following the corn flour tan came the slow darkening towards burnt orange, but not without a new visual.

The low clouds over the City created a reflection of some kind, lines of orange would appear below the moon and slowly the two would melt together. At one point the detached line was a bit more red and dancing in the reflected heat of San Francisco. As the two merged it appeared that the lower edge of the setting moon had begun to flame and burn, as if it would need to quench itself in the Pacific.

The final setting was, as it has been for several nights, a complete distortion of the moon's crescent. Last night both the top and bottom tips of the quarter were lost in the over&undercast. Anyone peering through my magic glasses at that moment would have seen a large orange blob just above the buildings of the city. No one would have guessed this was the perfect quarter we had seen twenty minutes before. Finally, instead of descending behind one of San Francisco's many hills, a misty grey cloud rose up and consumed the orange and it was gone again until tonight

Removes the colours from our sight
Red is grey and yellow, white
But we decided which is right

Celestial Views

I'll put the photo credit up top when it's actually me, so yes that is my picture up there. That is the sky I woke to this morning and that sky will be the focus of my next series of posts. With apologies to my olde friend Lee, eastcoat Lee not southwest Lee, but with apologies to him and anyone else who has tired of my sky gazing... the next week or so will be an extended meditation looking out my window. In last Sunday's post (two down the scroll) I wrote about the moon setting into the skyscape of San Francisco last Saturday night; well, of course, it has done something similar but completely different every evening since. Each night the illuminated portion of the moon gets bigger, it was quartered last night. The hills and buildings of the City that are descended thru shift and the atmosphere, clouds and light change the images sliding through my view. 

What with the earth rotating, the moon setting later each night, the cloud cover shifting, the moon becoming fuller -- the show offers new celestial perspectives each and every night. Add to that the sunset continues to march south and has reached the north end of the Golden Gate narrows (and bridge), this all portents some really interesting sky viewing over the next week. 

The moonset timetable will require some late nights and dark mornings but if the last several days have been any indication it will clearly be worth the lost sleep. Besides there are a few sections of my current book that could use some dark of night influenced attention.

So don't call too early, I'm going deep nocturnal for awhile and together we will ponder the skies through my window.

I can see it all
From this great height
I can feel the sun
Slipping out of sight
And the world still goes on
Through the night

White Bird and other things



One of my faithful readers is also an OCD nit, she likes to track any promises I make and hold me to them or as she says: "I only bug you to follow up on things I am interested in." Apparently one of those things comes from a post last April where I observed a bevy of white birds in my neighborhood. Actually they tend to flock three or four blocks west of here and each time I walked down there after spotting them, they had vanished. This weekend I got a 'white bird' reminder from my friend and avid reader, then this morning there was the brood flying around down the street.

I first watched them wheel about in the area the size of ten or twelve residential blocks, this seemed to me to be the same relative area they had covered when I first noticed them. Either they had taken the summer off or I just haven't been as avian observant lately. First there were five or six birds but soon the rest of the drove rose up to join them. About a dozen in all with at least two thirds of them white as snow. Finally about half of the skein lighted in that same evergreen tree and the others on a double span utility pole. The pole was clearly visible so I peered through my super binoculars and saw six birds (four white) very clearly but what were they? We must have our labels.

I tossed on the sneakers and headed out hoping to catch them. About a block from the house I saw them in flight again but they often liked to double back so I kept after them. Here I was a humanoid on foot chasing birds on wing, next week I chase down roadrunners in Arizona. Just as I was feeling a tad stupid, I came out from under a big olive tree and there was the utility pole with nine birds perched on it. Six were indeed pure white and one of the other ones was clearly a standard, everyday rat-with-wings pigeon (bottom row center in the picture above).

Seeking verification of this congregation, I asked the store clerk on the next corner about the birds, he looked at me like I had asked for live tarantula ala mode. The homeless guy saw me looking up at the multitude and told me they were -- "the birds of peace." This piece of information comes with neither citation or nor corroboration. 

I did a little net research when I got back, here is what I found:

The difference between doves and pigeons is mostly size. Doves are generally sleeker and smaller with pointed tails, while pigeons are larger and stockier with rounded tails. The common urban pigeon is also known as a "Rock Dove." The popular white dove releases at various celebrations are billed as "dove" releases, but ethical companies always use white homing pigeons, as they return home.

Ethical in that they do not release tamed doves into the wild to fend for themselves. Ethical, not so much, in that they can sell them over and over again, well Viva Capitalism! 

By the way, I was unable to use army, assembly, cloud, collection, colony, company, convoy, crowd, crush, drift, drove, gaggle, gathering, group, herd, host, legion, litter, mass, pack, progeny, rout, scores, throng and I would have liked to have worked in an exaltation of larks or an ostentation of peacocks.
