The phenomenon of the Sun Moon

The phenomenon of the Sun Moon

On Friday October 2, 2009, around 11:00 pm, the sky is decorated Padang unique phenomenon, namely the sun looks like a ring surrounded by a circle of rainbow.

This phenomenon is commonly referred to as the phenomenon of 'hello'. These are generally found during the full moon or when the sun shines bright in the daytime.

This phenomenon is a kind of optical phenomenon that displays a ring around the source of light. This is due to reflection and refraction of light from the sun / moon by ice crystals or water vapor in clouds Cyrus, so the circle of light that displays the appearance as if there is a rainbow around the Sun or the Moon.

This halo phenomenon is not really a monopoly on the phenomenon that occurs when an area is affected by the earthquake. Often this phenomenon appears in some areas not affected by the earthquake. Among them, recorded have occurred in Bandung, Bogor, Jakarta, on 27 September 2007, then in Napier on 29 October 2007, then in Padang on 29 March 2008.

However, the halo phenomenon related to the reflection and refraction of light the sun / moon by water vapor, if associated with the phenomenon of earthquake clouds associated with moisture, it is can be both a correlation relation among these phenomena.

In the sense of the word, so could be the result of plate collision that resulted in an earthquake the earth's crust, it triggers the increase of air temperature at the site, then triggers an increase in evaporation of water, creating water vapor concentration of particles, and cause halo phenomena which is the refraction of sunlight.

Really can be, this earthquake clouds actually have appeared in the sky desert town, but due to thin clouds that then mark its presence is a circle of light around the sun, or a halo.
