Notes from Dr. Borkosky

"the summer solstice"--the noontime Sun soars high in the sky.

The calculator uses Sun position algorithm to calculate sun altitude.

Living and Learning in Alberta and California. Also calculates shadow growth during whole day. This year, as you say, is certainly one that will cause a lot of food for thought.

You should switch your furnace on, Mary Beth! Days are long, it gets hot, and we call it summer.

Also calculates shadow growth during whole day.

The asphalt, normally criss-crossed with the shadows of trees, will be bare and hot--all sunlight and no shade.

One of the distinguishing features of a northern winter is that the sun is very low in the sky, even at noon.

They begin long in morning, get shorter during the day, become longer again in afternoon.

Try moving your mouse pointer over the time symbols to pause the animation at that particular time. What are the characteristics of the Solar System?

On June 21st--the first day of northern summer, a.k.a.

In June, the Sun is high in the sky. It is everyone’s annus horribilis. It sets somewhere between 6:00 and 6:30 PM. Gives a vertical object shadow length for given coordinates and time. a - angle between Sun and horizon. The planet Uranus, for example, is tilted 97 degrees.

2020 presents so very much food for thought. I’m glad you have green grass and leaves on the trees, Barb. ( Log Out /  person_outlineAntonschedule 2012-03-29 18:52:42. The Seasonal Merry-Go-Round -- (Windows to the Universe) the basic geometry of seasons. But later today, around lunchtime, Shaq's shadow will measure barely 1 foot 4 inches.

Sorry, your blog cannot share posts by email. The collision created the Moon and, perhaps, knocked Earth a bit on its side. The south pole is tipped away from the Sun, so mid-day shadows south of the tropics are longer than usual.

Just about time to switch the furnace on I think! If Shaq flew to Buenos Aires for lunch today, his shadow would stretch an impressive 11 feet 4 inches--16 inches taller than a regulation basketball hoop. Registration for the Astronomers Without Borders Asteroid Search Campaign is now open! Look again in six months and you'll see a big difference, something like this: Shaq's summer shadow: 1 foot 4 inches.

He certainly looks unstoppable.

The NBA All-Star weighs 315 lbs and stands 7 feet 1 inch tall. It is a delight to me to get to sleep until 7 because Buddy does not see daylight until around then!

This simple online calculator gives a vertical object shadow length for …

That's when the sun is directly overhead and light is completely blocked. They are hiding underneath cars, beneath trees and underfoot.

It has been a year that will require a lot of processing!

And, incidentally, Shaq's shadow in Los Angeles on June 21st would be 10 feet 6 inches long--all day long! I am a snowbird who travels south for the winter.

Shadows are equally long at sunrise and sunset, shortest at noon. The north pole would be hotter than the Sahara desert during summer, while tropical oceans would freeze. October 27, 2020 October 26, 2020 Snowbird of Paradise.

Too much tilt would cause seasons to be extreme. How do Earth, the planets, and the heliosphere respond?

And, I’m glad I rarely have to drive anywhere! Theoretically there should be no shadow at noon. The situation is reversed in the southern hemisphere. (Seasons are reversed south of the equator.). As you know, this may happen at night time :). Our furnace kicks in at 20C which is about 68F, so yes. If Earth were like that, most of our planet would experience nights lasting weeks or months (depending on latitude).

On Sunday, while walking in Borden Park in Edmonton, I noticed how long the shadows were. One of the distinguishing features of a northern winter is that the sun is very low in the sky, even at noon. I am given these dark times to go inside myself and consider where I have come in this passing year.

Some astronomers believe that, about 5 billion years ago when Earth was very young, our planet was struck by a Mars-sized protoworld. Shaq's winter shadow: 11 feet 4 inches.

I noticed the thermostat reads 65 degrees this morning. Unauthorized use and/or duplication of this material without express and written permission from this site’s author and/or owner is strictly prohibited.

The reduced hours of daylight have an effect on all of us, but for some of us it is definitely a time for hibernation and/or introspection.

It has its own beauty in Edmonton, but here the grass is still green and the leaves are on the trees and I am so glad for that. On a sunny day in winter, motorists need sunglasses all day because the sun never seems to rise above the windshield. Even here I am quite aware of the sun being much lower on the horizon now and, until the time change on Saturday night, the sun rises at about 7:15 AM. If Earth had no tilt we would experience no seasons: no crisp winter days, no autumn leaves, no spring cleaning, no summer vacation. This happens because our planet's spin axis is tilted 23.5 degrees.
