RE: Orionid meteor shower
Meteor shower Oct. 21 should be a sight, so find dark spot and get comfortable
In all the hustle and bustle of everyday life, how often do you stop and take some time to look up? On the morning of Oct. 21, I would suggest you make some time because the Orionid meteors will be showering the sky.

More than any other month, stargazing enthusiasts await for the month of October for a handful of planetary and meteor shows, one of which is Orionids which is carried off by the famous Halley's Comet.

The Orionid meteor shower is expected to reach peak activity this year on October 21st. Unfortunately for observers, however, we will also be under a waning gibbous moon.

Unusually clear skies gave a handful of Puget Sound residents a glimpse of an annual occurrence -- the Orionids meteor shower.
The shower -- which hit its peak Sunday, according to the American Meteor Society -- happens when dust from Halley's comet collides with the Earth's atmosphere each year.

On the night of Vijaya Dashami, October 21, Nepalis across the nation will see a celestial firework with hundreds of shooting stars in the north-east sky as there will be Orionid meteor shower for several hours for the first time in 11 years.
Experts predict that the Orionids could be better than average this year, with perhaps a score of 20 yellow and green meteors per hour, which are fast moving at 41.6 miles per second. The shower could be observed from the midnight till four in the morning across Nepal.

The annual Orionid meteor shower peaks early Sunday morning and could put on a delightful display for skywatchers with clear, dark skies.

The Orionid Meteor Shower will peak on Saturday night of this week but meteors from this shower can be seen tonight until early next week. The Orionid meteors are fast and moderately bright and although they can be seen anywhere in the sky they appear to originate near Betelgeuse, a star in the constellation Orion. The best time to view is after the moon sets for maximum sky darkness.

Under cloudless skies, the Orionid meteor shower may make a fine display peaking on October 21 to 22.
The annual meteor shower occurs when Earth passes through the debris stream of Comet Halley, and meteoroids hit the atmosphere at 66 km/s (about 148,000 mph).
The shower is the second of two meteor showers that occur each year as a result of Earth passing through the dust stream; the first is the
The Orionid shower starts on the 17th of the month but will peak around the night of October 21 and will continue until the 27th.
Under favourable conditions, about 20-25 Orionid meteors will burn in the sky
" - Elenita Ingalia, officer in charge of Astronomical Research and Development Section at the Philippine Atmospheric Geophysical and Astronomical Services Administration (Pagasa).
Meteors are small fragments of cosmic debris entering Earth's atmosphere at extremely high speed. They vaporise due to friction with the air, leaving a streak of light that very quickly disappears.
It is thought that Halley's comet sheds a blanket 6 meters thick of dust and ice on each pass.
Most of the small fragments of comet debris are smaller than a grain of sand, so almost all fragments disintegrate and never hit the earth's surface.
For observers around 40 degrees north latitude, the radiants rise high in the eastern sky (at least 45 degrees up) by about 2 a.m.
To find the Orionids, go outside and face South-southeast towards the constellation Orion. The radiant lies NE of
, near to the border of Gemini.
Visible nationwide, the Orionids are faint and swift. They are best seen just with the naked eye.
The average brightness is around the magnitude 2 to 3; the same as the stars in the Plough.
But fireballs can be expected around the maximum. The expected ZHR (Zenith Hourly Rate) is estimated at 25 meteors per hour.
The meteors don't have any colour/ white, and sometimes leave a glowing green ion train in their wake.
Stay away from city lights though, because bright lights can spoil the visibility of meteors
" - Elenita Ingalia.
Aside from city lights, thick clouds can ruin the event. An evening gibbous moon should not hamper too much the shower this year.)
