TEAM CANADA! (Page 11)

I missed my Thursday morning swim this morning as I had to drop a neighbour off at the Airport. But I will be swimming tomorrow morning (Friday) and have confirmed that the pool will be open next week Wednesday and Friday so I will be finished Friday December 30th with 103% completion....

Go Crazy Canucks!

Just put another 1750m on my total.. leaving me just shy of 5k to complete. 9 days? Meh - not a problem. You guys can count on me

52km to go, with a friday workout this week. Then I looked at the schedule for next week:
Tuesday AM&PM, Wed AM&PM, Thurs AM&PM, Fri Am (all of those 2hrs), fri PM (1.5hr), Sat AM 3hr.

Of course, there's no way I can subject my body to that, so if I make 7, I'd be on the bubble of 100%

If anyone can do it Greg you can. Swim baby swim!

Happy Holidays to all! I am chomping at the bit to get back in the pool - all pools have been closed from the 19th to the 26th. Make no mistake, though, my 10k commitment will be completed!

+ 4 Celsius here this morning - going to be a warm Christmas.

1550 meters completed this morning. Week total 3100 meters. Month total 10,950 meters (81% of my 13,500 meter challenge completed).

Merry Christmas Everyone! Joyeux Noel!

Not swim related, but it was +10 here this morning. Not really out of the ordinary this week, but we actually had a THUNDERSTORM yesterday afternoon. Now how's THAT for bizarre in the middle of December?

You and your chinook winds can kiss my backstroke fastkin's rear... lol

2,425 to go kids and you can stick a fork in me!! (I will be done!)... Saving a little yardage (meterage?) for after the holidays...

YAHOO!

Forget the temperature--today Anchorage is picking up 20 seconds more of light (yesterday we gained 7 seconds)...I love it when we start to turn our faces to the sun again!!

Happy Holidays...

how do you find out how many seconds you pick up?

They tell me on the radio every morning (gotta love Alaska Public Radio Network)... I sure there is probably some web site out there that would also do the same...

88k as of this morning. We're going another 6 this afternoon.
If I were to assume 6k for both of tomorrow's workouts, thursday's and friday's, and 10k for sure saturday, I will be 128k of 130k.

That's incredible Greg!

I'll be swimming tomorrow (Wednesday) and Friday and that will put me over 100% of goal. If I could swim 2 km more and pass those laps on to you I would! But there's no cheating on Team Canada's team and no sandbaggers either. Great job everyone!

you wanted to know...lol

Since refraction affects zenith angle,
it generally changes both the Right Ascension and declination of an object.
It also affects the time the object appears to rise and set.

The standard formula for the altitude of an object is:
sin(a) = sin(d)sin(f) + cos(d) cos(f) cos(H)

If a = 0° (the object is on horizon, either rising or setting),
then this equation becomes:
cos(H) = - tan(f) tan(d)

This gives the semi-diurnal arc H:
the time between the object crossing the horizon, and crossing the meridian.

Knowing the Right Ascension of the object, and its semi-diurnal arc,
we can find the Local Sidereal Time of meridian transit,
and hence calculate its rising and setting times.

However, refraction means that this simplified formula is not accurate,
since the altitude should be, not 0°, but -0°34'.
This is not too important for stars, which are rarely observed close to the horizon.
But it makes an important difference in calculating the times of rising and setting of the Sun.

Furthermore, "sunrise" and "sunset" generally refer to the moment
when the top of the Sun's disc is just on the horizon.
The formula would give us the time of rising or setting
for the centre of the Sun's disc.
So we must also allow for the semi-diameter of the Sun's disc,
which is 16 arc-minutes.

So sunrise and sunset actually occur when the Sun has altitude -0°50'
(34' for refraction, and another 16' for the semi-diameter of the disc).

Since the atmosphere scatters sunlight, the sky does not become dark instantly at sunset;
there is a period of twilight.


During civil twilight, it is still light enough to carry on ordinary activities out-of-doors;
this continues until the Sun's altitude is -6°.
During nautical twilight, it is dark enough to see the brighter stars,
but still light enough to see the horizon, enabling sailors to measure stellar altitudes for navigation;
this continues until the Sun's altitude is -12°.
During astronomical twilight, the sky is still too light for making reliable astronomical observations;
this continues until the Sun's altitude is -18°.
Once the Sun is more than 18° below the horizon, we have astronomical darkness.
The same pattern of twilights repeats, in reverse, before sunrise.

In summer, astronomical twilight will last all night, for any place with latitude above 48.6°

wow, I even tried to understand that... ummm what's d, f, and when you say arc-minutes, are you talking about 1/60th of a degree? If so I don't see a time component. If not then you have a weird way of describing time.

I could try to explain it to you but my head would explode if I even began to know what I was talking about!

Temp -1. Too warm for this time of year...

Another 1500 knocked off. 12,450 meters of 13,500 goal. Will complete goal on Friday! Hooray!

Team Canada stats?

I've noticed Crazypop has not picked up my PM from December 23rd so I suspect he is off on vacation. Could each of you please PM me with your swim totals for the week ending December 25th? I'll compile them and PM Renee.

Thanks,

Steve (Calgary Runner)

Friends! I have completed my 35K as of this morning at 7:10 am... YAHOO! Team Canada (et al) thanks for allowing me to play!

I went into each team members log over lunch and compiled the following spreadsheet for Renee re our teams current standings...

Congrats to those of you who completed your goals!
