Sun's Location
 

By my fist sighting, I put the Sun 234 miles south of the Equator today.

Our winter is about to descend on Ozzy's land. Getting ready for;
Welcome Sweet Springtime. in the Northern hemisphere.

Soon to have Long Days and short nights at Lat. 48N. Returning at 2200
and docking in daylight.

Thats great news Thom!

And by my planetarium sighting, it's declination today is just about 5degS.
That would put it overhead at 300 miles south of the Equator. 234 miles
equates to a declination of about -3.9 degrees.

Wally,

Admittedly my method is very crude but with 5 degrees to go to the
Equinox that is about 3.3 days per degree and at this section of the
seasonal sine wave that does sound rather fast for the revoltional speed
of the earth.

3.9 was what I figured. That would be about .26 degrees a day. We'll
know in about 15 days won't we?

4 equal seasons divided into a 365 day year would 91 1/4 days. At 3.3
days per degree the seasons would almost be 72 1/2 days long. I could be
wrong and I know the rate varies ( Sine Wave) but I'm pretty sure the
rate of change is the fastest crossing the Equator. My method is a
guessation and I use the RMS rate for my guess. We'll see. 1.1 degree (
60 miles +) in 75 days using no instruments and no tables, I'm pretty
happy with the results

Keep in touch

Good calculation Thom. It's not the revolutional speed of the earth it's the
precessional speed. It is the fastest at the equator and the dwell time is
longest at the summer and winter equinoxes.
The rate of change of a sine wave is a cosine wave. The cosine function is
at a maximum of 1 when the argument is at 0 degrees. The argument used in
the sine function for position should be the number of days away from the
day with equal dark/light normalized to k*pi radians. The k is to fudge for
complete darkness near the poles.

It is extremely gratifying to see what is possible under the tutelage and
inspiration of our own learned Master Mariner, the good Capt Neal. Ole Thom
has clearly demonstrated that, good thinking Ole Thom!

Amen!

It's about F'ing time!

Ah Scotty,

We must have winter or we would never truly know the joys of summer; we
need nights to know the gift of daylight!

Be still sad heart and stop repining;
Behind the cloud is the still shining.
Thy fate is the common fate of all;
Into each life, some rain must fall.
Some days must be dark a dreary!!!

Good nite one and all. Time for Ole Thom to go to bed.

This has been a weird Winter. On Monday it was 66*, nice warm breeze,
felt like a sailing day. Most of the snow melted. On Tuesday it
dropped to 16*, snowing with 40mph winds. Ahhhhhhhhhhhhhhhhhh!

Wally,

I've got the Sun 180 miles south of the equator. What is the exact
location?

Ole Thom

Scotty,

When I was back there, this storm you're having was classified as an
"Onion Snow"
Winter's parting shot.

I cut the grass for the second time yesterday

Ole Thom

I've seen Onion Snows as late as April. Grass? Oh that green stuff,
yeah, I remember it.

Couldn't get a "Noon Sight" today. Cloud cover. Last one was 4 fists &
4 knuckles from a Lat 48'8" minus 47'5" that would be 3'30" + another
day at 26 mile rate. I figure 180 miles close enough for ASA work.

Wally,

How about you giving us a more exact reading on the 14 th of march? I
would really like that. My Sun tables are outdated by about five years
so even with my sextant reading I'm still estimating.
Keep me honest with your Planetarium

Thanks,
Ole Thom

Got a Noon "Fist Sight" 4 fist and 3
fingers. That put Ole Sol probably less than 60miles and I'm running out
of days.
Looks like Wally's reading was dead nuts on.

Anyway, Sun about to be on our side very soon




http://community.webtv.net/tassail/ThomsPage

My "Fist Sight" hit 48 degrees today. If I've been hitting them close,
I'm working on forty-eight minutes with four days to go. Looks like my
sighting will be at the equator at least a day ahead of the sun.

Could be in error between twenty to forty miles. Rough but I don't feel
to bad about my free hand sighting.

Get a fresh start on the 20th. I may try modifying RMS to 68% & 32% on
the next 91 1/4 days

Ole Thom

Yeah, but when do we spring forward with the clocks?

Joe

April 3rd.

"Spring ahead April 3" Joe.

Changes "Local Noon" out of whack with GMT.

Doesn't make to much difference to this old Man. All my cruising is
contained within local knowledge areas.

The easy Navi is just for fun. Getting Closer and closer. I think I can
bring it within somewhere between a 1/4 & 1/2 degree with the Sun Noon
Sights. I just might try some Star sights this year.

I've gained a hell of a lot more respect for the old sailors before
compass Tech. I have very little doubt about them knowing where they
were going or where they were.

AND: "I'LL DRINK TO THAT!"

Cheers,
Ole Thom

Some where in the fourth finger. Fist sights and days/degree beat the
Sun to the Equator by about a degree+. :^) Will adjust on the 20 th.

Kate;

Just talked with MN for you and was told to SHUT UP! The BIG POWER has
other problems to take care of in the Universe. Mother will that care of
us when she gets the OK.

I explained about Sun position and Sun sights and got a SO WHAT!! in
reply. I was also informed I was wrong about the position by at least a
full degree and something about "damn spoiled brats"

Will start new sights at zero tomorrow.

Happy Equinox a day early.

Well, you shouldn't a autta asked because in retribution she sent another 3
inches of snow...we were supposed to have 42 and rain today but got winter
all over again instead!
This fool robin is sitting out in my cherry tree trilling away....I thionk
he's singing to stay warm...
