    THE AURORA

Auroras, sometimes called the northern and southern (polar) light are natural light displays in the sky, usually observed at night, particularly in the polar regions. They occur in the ionosphere.

Auroras are the result of the emissions of photons in the Earth's upper atmosphere, above 80 km (50 miles), from ionized nitrogen atoms regaining an electrons, and oxygen and nitrogen atoms returning from an excited state to ground state. They are ionized by the collision of solar wind particles being funneled down and accelerated along the Earth's magnetic field lines.

Aurora are associated with the solar wind, a flow of ions continuously flowing outword from the sun. The Earth's magnetic field traps these particles, many of which travel toward the poles where they are accelerated toward earth. Collisions between these ions and atmospheric atoms and molecules causes energy releases in the form of auroras appearing in the large circles around the poles. Auroras are more frequent and brighter during the intense phase of the solar cycle.

A MAN, A BOY, AND A LADY

There was a small village in the forest in a mountain on the east side of the earth. In the village lived a man with his son. His name was Jeremiah and his son was Clay. They lived in an old huge mansion, which was a guest house, quite far from the village. The house looked scary on the outside and the mansion’s owner also not a friendly person, but actually he had a kind heart even though they’re not rich.

One rainy and stormy night, came a beautiful young lady at the same age of his son. His son felt something wrong with the lady but he kept it inside, because he didn’t have evidence about his feeling. He kept an eye on the lady every time, every second, and every of her movement.

After dinner, the Lady asked them if they allowed her to stay for a night, as she had no house to stay. They allowed her to stay and prepared a room for her. Clay delivered her an extra blanket, it was very cold outside. He knocked the door but no one answered, then he tried again. He decided to wait, but five minute passed, he ran out of patient. He opened the door which apparently was not locked and stepped his feet inside the room. The room was so dark and the only light came from the opened window.

The thunder stroke a tree. He put the blanket on the bed and ran to shut the window. When he shut the window, he suddenly realized that no one’s in the room. He wondered where the lady was. There was no sign that the lady left the room, so he searches for her. Starting by opened the bathroom. At first, he saw nothing and no one, but as he walked to the bathtub he saw something dropping from the ceiling above the bathtub. He looked up and saw a body hanging on the ceiling. He called over his father but when his father arrived and Clay turned his head for a second, the body disappeared. They soon found that the lady was the first owner of the mansion who was committed suicide 50 years ago. That’s the reason why the guest house was closed.
