Fading ISS orbit

“Normally, the best times to see the ISS are within an hour or two before sunrise or after sunset. During those times your sky will be dark (barring urban light pollution) but the high-flying ISS can still be sunlit. In the evening the station will look brightest just before entering the Earth's shadow and suddenly "disappearing" partway across the sky. Early in the morning the ISS can abruptly "appear" as it emerges from Earth's shadow.”

I decided to actually look up why the Space Station fades from view as it passes overhead. I’m relieved to find out that my theory was right.

An Eventually Identifiable Object (EIO)

Last night I took Shelby outside for her next-to-last visit to the backyard for the evening. I was leaning against the side of our garage looking at the slice of night sky that is visible between the two houses across the back lane. I noticed two really bright stars and I thought to myself, “That’s odd to see two bright stars so close together.”

Normally there are a handful of bright stars on display that really stand out, highlighted against a multitude of stars that are at least semi-veiled from view due to the lights of the city. At various times of the year local solar system planets park themselves in an orbit that makes them visible to the naked eye. In other words, they show up looking like bright stars in Earth’s evening blackness.

I thought these two bright objects must be a planet and a star, or two planets in complementary orbits. I watched them for a few seconds; then I turned to see what Shelby was up to, then back again to the stars. I could swear that one of the bright objects had moved in relation to the electrical power line that crossed my field of vision. I looked at it more critically this time, with specific focus on its suspected travel.

It was indeed moving. Next I had to determine what it was. I had a pretty good idea in mind already. As it approached I detected no blinking lights, which would have been the tell-tale signs of an aircraft.

The reason I was somewhat confidant that I was watching the International Space Station (ISS) is that I saw it on Saturday early evening at Ambleside Park when I was at the Summer Sessions concert. The only difference was that on Saturday night it was traveling from South West to North East, and tonight its trajectory took it from West to East.

The thing that intrigued me the most the other night, and again this night, was that I wasn’t able to watch its whole arc across the sky. I thought I’d be able to follow along until the ISS was obscured from view by the roofs of houses, but it faded from view long before that. I was craning my neck almost straight up when the ISS started to become dimmer and dimmer. In a matter of seconds it was entirely cloaked in inky blackness.

I kind of felt like a scientist at that point, putting an experiment through its paces in hopes of finalizing a thesis, or verifying an assumption. The first time I had witnessed the ISS fade from view before it could cross the horizon line was Saturday night, and now I had my confirmation; for reasons yet unknown the ISS traverses a portion of the visible night sky, visible to all that look up, and then fades when it reaches a certain altitude, or orbit, or intersection of the sun’s rays in the upper atmosphere.

I know I could look it up on the Internet if I felt like it, but I’m really more what you’d call an 'armchair astronomer'. I like looking at the night sky, the darker the better, but I’m not interested enough to crack an astronomy text book and actually study it. Somehow for me, knowing the answers to some of nature’s celestial charades (i.e. orbits) would take away from the wonder of the moment.

Sarah McLachlan’s Summer Sessions concert, Sept. 12, 2009, Ambleside Park, West Vancouver

I can’t remember if Sarah McLachlan specifically said, “The stars have aligned for this event,” but they actually did in many respects.  For one thing, a shooting star skidded across the sky at dusk, between sets, eliciting a burst of applause from the audience.  I only caught the tail end of it; my wife said it was a long comet.  The portion I saw looked like a trail of fireworks not unlike something from the Nights of Fire celebrations.
Later in the evening, as I was listening to Neil Young’s set, my gaze travelled up and I noticed that the stage was perfectly placed under the Big Dipper.  In the city, star constellations are generally a bit dim but the Dipper was easy to spot.  Only the top attachment point of the cup to the handle was obscured by atmospheric haze.
The last sky-related item was the passing overhead of the International Space Station.  I’ve heard radio announcers say lately that they’ve seen it pass overhead. My eyes have followed the slow arcs of satellites through dark night skies in the past; this slow-moving speck in the sky was a lot larger and brighter than any satellite I’ve seen.
But of course, the stars Sarah was referring to were the scheduled line-up for the day and evening performances.  We arrived in time to hear Luke Doucet.  I “ iTuned” his latest release “Blood’s Too Rich” at Christmastime, just minutes before we had to leave for the airport to catch a flight to Winnipeg.  The flight was delayed and I listened to that CD about 3 times that evening (and that was just in the airport).  I really like it.




I didn’t know of Melissa McClelland prior to the show, but it turns out that Luke and Melissa are married. I have to say, I was impressed with Melissa’s bluesy style. She has a really good voice. The set Luke and Melissa performed was acoustic, just the two of them with guitars, and it was a nice blend of each one complimenting the other’s songs. Both have CDs out. One part in particular stood out for me, because I’m familiar with Blood’s Too Rich. Melissa vocalized the notes to a guitar riff for one of Luke’s tunes.
Sheryl Crow was the rocker of the night. She performed a string of her hits, one accompanied by Sarah McLachlan, putting to rest early any doubts that Sarah’s voice wouldn’t be up to snuff after a bought of laryngitis this past week.
Neil Young’s set was a bit late to start but well worth the wait. This is the third time I’ve been to one of his concerts and there are definitely two styles: rocker and “intimate session”. It’s almost like two different performers. Of course, I never saw him perform until recent years so I probably missed his hard rocking prime. I’m sure he wasn’t crowned “the grandfather of grunge” for nothing. But this Summer Session was like singing campfire songs with your favourite, though somewhat non-conversational, uncle.
Banter between songs was very minimal, and sometimes inaudible because Neil was reaching for a guitar, or busy plugging one in. I guess that’s all part of the draw of a front row seat. He spoke about Sarah McLachlan briefly to say she had been very supportive of the school that Neil and his wife, Peggy, were involved in running. “You’ve got a good one there,” he said when speaking of Sarah.
It struck me that it’s almost like a spiritual experience to see Neil Young; a pilgrimage of the faithful to witness the culmination of forty-some years of rock and folk wisdom dispensed by a veteran of sixties culture. It was quite fascinating to sense the vibe of the crowd during Neil’s set. The word that seems to fit best is ‘reverential’. It was a service conducted by Reverend Neil, and it seemed especially fitting that it was an outdoor service. Somehow that seemed to make it all the more congregational .
Neil was the top draw for a substantial portion of the audience. His stage set-up was to sit in the middle of a circle of various guitars and one banjo. Most of the songs were played with one of those guitars, or the banjo, or guitar with harmonica, and one selection he played on the piano. He was accompanied by Peggy on vocals, and a fellow musician on the slide guitar.
I wasn’t sure what to expect when Sarah’s turn came. I like her music, but to be honest, I thought it would be a bit too mellow for such a large outdoor venue. I was wondering if it would be only Sarah and her piano. That turned out to be the case for her opening song, but after that she continued with Sheryl’s back-up band for a few faster paced songs (plus a duet with Sheryl), then some quieter songs with Luke Doucet and Melissa McClelland helping out with guitar and vocals respectively. She even did a cover of a Beatle’s tune.
All in all it was a very enjoyable afternoon and evening of diverse musical talent.
And yes, the food was expensive, but at least the barbequed burgers were large and tasteful. And your three bucks got you a twist-capped plastic bottle of Pepsi instead of merely a can. I’m no event organizer to be sure, but it seems to me that it can’t be cheap to set up three temporary camp kitchens on a grass playing field, truck in all the supplies, get permits, rent portable power generators for electricity and refrigerant, rent tents and cooking equipment, assemble a serving staff, employ trash removal services, rent portable toilet facilities, etc, etc. So lets lay off the “Gee, the food was so expensive!” Live entertainment, refreshments and sanitation services cost money.
The end of the evening came after Sarah’s two song encore; then everyone packed up their things and filed out of the fenced concert area. We headed for the East gate to follow the bike trail to buses parked at Park Royal mall. As we approached we could hear a DJ that had set up at the smaller stage. Mo-Town tunes were pumping and there was a small group of people dancing to the groove. Then I noticed the fire jugglers (two of them), and a fire breather of all things! It felt like we’d stumbled upon Burning Man; a real carnival-like atmosphere to be sure.
After watching for ten minutes or so we continued our walk along paved pathways lit by generator-powered flood lamps. To top it all off, when we arrived at the water’s edge, there was the Lion’s Gate bridge, with its gracefully arched cables outlined in lights and the uprights brightly backlit.
It was indeed a summer session.
p.s. I wanted to 'fess up about the grainy photos that I used in my post. I used the "hyper" digital zoom on my camera, with no tripod, at dusk (and even later), from a distance of 1/2 a soccer field away. Oh yeah, and I photgraphed the huge jumbotron screen, not the actual performers themselves. I tell ya, that camera is magic! Plus it fits in my pocket. I'm the kind of hobbyist photographer that's all over getting the biggest digital technological wonder that will comfortably fit in my pocket.

The manager of our department had an interesting non-work related idea yesterday. He came in all excited that it was Sept.9, 2009.

So, what's the big deal?

In other words it’s 09/09/09. That doesn’t happen every day. "And furthermore, at nine minutes past nine in the morning it’ll be 9:09/09/09/09. Get your cameras out! We gotta get this on film!"

Pretty good idea actually. I wasn’t paying any attention to the date. I would have missed it completely.

And, wouldn’t cha know it, I was so engrossed in writing my report that it slipped my mind as the magical minute approached.

Suddenly a colleague exclaimed, “Hey, it’s 9:09!”

And my manager right away said, “Get your cameras!”

By the time I grabbed my camera, turned it on, changed the setting to close-up and aimed at the digital read-out on my desktop land line, it had clicked over to 9:10.

Silence.

Then an expletive from someone.

No one in our department got the shot. All that build-up and we missed it by mere seconds.


However, I redeemed myself later that evening at home. I placed my camera on the coffee table beside my cell phone, upon which I stuck a Post-It note with the numbers 9:09.

Bingo. Here’s the result.














Now I have to wait a bit more than a year for the next opportunity; 10:10/10/10/10. Does this mean I’m a numbers geek now?

Perspective

I have a question for you. Who thinks $64,000 a year is a decent salary? Show of hands? OK. I’d guess about 90% of you agree with me.

And that agreement is despite the fact that sixty four grand is not even enough to qualify for a mortgage in this town (Vancouver, that is).

For the following blog post I feel obliged to submit full disclosure: I’m not a true blue, dyed-in-the-wool, Canucks fan. I’m a bandwagon jumper. If they’re in the playoffs I’ll watch most of the games. And if I’m given free tickets, I’ll certainly go to the game and quite honestly enjoy myself.

And I know the Canucks organization as a whole gives a lot back to the community. I know of Canucks Place for sick children, and there are probably many more charities they contribute to, of which I'm not even aware.

And I’m sure Mr. Luongo is a very nice person if you get the chance to get to know him.

Stay with me, I do have a point. I subscribe to the editorial crescendo effect.

What I’m really getting at isn’t even really confined to the Canucks organization; it’s very much more widespread throughout the professional sports world.

Here’s my point. A sixty-four million dollar contract? That phrase really has to be delivered in a Dr. Evil (from the ‘Austin Powers’ movies) tone of voice. “Sixty-four million dollars?”

To put this whole financial vehicle into a more “Average Joe” perspective, the lump sum contract amount (64 mil over 12 years) breaks down to five and a third million dollars a year. Or 83 times that baseline salary about which I asked your opinion at the start.

In other words, it would take the average Joe earning sixty-four grand a year 83 years to earn what Mr. Luongo will take home annually.

I hope this doesn’t come across as sour grapes. That’s honestly not my intention. But I do think it’s beneficial to stand back and observe the big picture once in a while.

Sixty-four million dollars. Remember, that's only for one player.

To big league sports owners/ general managers everywhere I say, “Give your head a shake!” And more importantly, don’t start blaming Joe Average for not supporting the home team when your unsustainable business model begins to bleed red ink and the banks threaten foreclosure. But that’s a rant for another day.

One final observation: How did a simple game of shinny escalate into a billionaire boys club?

Celebrity watch

Here’s probably your first back-to-school story of the year. My wife teaches at a private school and they start earlier than the public schools (this year, at least). My wife’s work colleague’s best friend’s cousin is the long-time girlfriend of the guy that played the part of Allen in the recent movie “The Hangover” (very funny movie, BTW).

By my trusted fingers and toes calculation method, I’d say that make for six degrees of separation between me and “Allen”.

How’s that for a brush with celebrity?

Albeit a brush to the 6th degree.

Dazzling sunset

We took Shelby to Angus Park a couple of evenings ago. The sunset was so compelling I just had to photograph it. In a recent blog post I had been bemoaning the fact that I had missed a spectacular sunset a month or so ago; the one that preceded the brilliant lightning storm on the night of the fireworks in English Bay.

Upon review of this recent sunset image, I think I may just have to let it go (it being the fact that I missed out on the previous opportunity). I like this image and it has a bit of that other-worldly feel to it; a Martian twilight perhaps.

I’ll post two sunset photos; the one I took at Angus Park, and an abstract shot I took of a wasp deterrent paper globe I hung on the beam of our deck, silhouetted against what looked like a raging forest fire, but was really just a dazzling sunset.
