Kuantan's lucky-bad day

[click the photo to enlarge]






because if this...


my neck hurts...


cause i keep looking at it a long time...






because of this...


i waste alot of money...



sending & replying message...



the same thing over & over again....



& my parents gonna kill me when they see the bill....









BECAUSE OF THIS!!!





i learn new things....



even waste my time surfing the net....



which the day after tomorrow is the final exam...



i'm still here....



writing this post....





.....




thanks to this natural phenomena....




i found the reason & how did it happen....




because i seen it for the 1st time....



and also....



lots of thanks to jonathan...




for telling me to search the right website....




even it signifies bad weather....




& soon we all are gonna die....







Go0d NighT....



May the ring of the moon give you some light....



While you sleep tight...










=)

M0re Details...

22 Degree Halo
a ring of light 22 degrees from the sun or moon

A halo is a ring of light surrounding the sun or moon.Most halos appear as bright white rings but in some instances, the dispersion of light as it passes through ice crystals found in upper level cirrus clouds can cause a halo to have color.

Halos form when light from the sun or moon is refracted by ice crystals associated with thin, high-level clouds (like cirrostratus clouds). A 22 degree halo is a ring of light 22 degrees from the sun (or moon) and is the most common type of halo observed and is formed by hexagonal ice crystals with diameters less than 20.5 micrometers.

Light undergoes two refractions as it passes through an ice crystal and the amount of bending that occurs depends upon the ice crystal's diameter.


A 22 degree halo develops when light enters one side of a columnar ice crystal and exits through another side. The light is refracted when it enters the ice crystal and once again when it leaves the ice crystal.


The two refractions bend the light by 22 degrees from its original direction, producing a ring of light observed at 22 degrees from the sun or moon.


A tangent arc is a patch of bright light that is occasionally observed along a halo. This occurs when sunlight is refracted by falling hexagonal "pencil-shaped" ice crystals whose long axes are oriented horizontally.

IS A BAD SIGN!!!

Moon Light Effects


1.Moon Ring


The moon can produce interesting optical effects when conditions are right.
The most common of which are moon rings, moon bows, which are similar to rainbows, moon dogs and moon pillars. A rainbow is produced when sunlight is refracted through water droplets - A similar effect is produced when moon light refracts through ice crystals. Below are a few photographs and examples about this interesting phenomena. Thanks to everyone that helped me put together this simple explanation of moon light effects.
A Ring Around The Moon

The ring around the Moon is caused by the refraction of Moonlight (which of course is reflected sunlight) from ice crystals in the upper atmosphere. The shape of the ice crystals results in a focusing of the light into a ring. Since the ice crystals typically have the same shape, namely a hexagonal shape, the Moon ring is almost always the same size.

Less typical are the halos that may be produced by different angles in the crystals. They can create halos with an angle of 46 degrees.

Moon Halo

Moon Ring Weather Folklore
Folklore has it that a ring around the moon signifies bad weather is coming, and in many cases this may be true. So how can rings around the moon be a predictor of weather to come? The ice crystals that cover the halo signify high altitude, thin cirrus clouds that normally precede a warm front by one or two days. Typically, a warm front will be associated with a low pressure system which is commonly referred to as a storm.

It is believed that the number of stars within a moon halo indicate the number days before bad weather will arrive. Give it a try the next time you observe a moon halo.

Rings Around The Sun - The same phenomena that causes lunar halos can also be observed around the sun. A few photos of solar halos using a Coolpix 995 digital camera. NOTICE: Never look at or photograph the sun directly.








Anatomy of a Moon Halo

The ring that appears around the moon arises from light passing through six-sided ice crystals high in the atmosphere. These ice crystals refract, or bend, light in the same manner that a camera lens bends light. The ring has a diameter of 22° , and sometimes, if you are lucky, it is also possible to detect a second ring, 44° diameter. Thin high cirrus clouds lofting at 20,000 feet or more contain tiny ice crystals that originate from the freezing of super cooled water droplets. These crystals behave like jewels refracting and reflecting in different directions.

Cloud crystals are varieties of hexagonal prisms, (6 sides) and range in shapes from long columns to thin plate-like shapes that have different face sizes.
