Leonids 2009

[Jazlan]

saya pon bru tau psl tuh...

[shahgazer]

ok i understand.. kiranya setiap nama meteor ini diambil apabile meteor itu melalui buruj2 tertentu la.

tq me_ai n shahgazer..

sedikit koreksi... bukan melalui buruj, tapi meteor tu muncul dari kawasan buruj tu, dan bergerak bersepah-sepah ke kawasan langit lain. Lokasi munculnya meteor tu dipanggil sebagai radiant meteor tersebut.

setelah baca teori cara mencerap meteor Leonids saudara Shah, praktik kan lah.

Ahli FO ASTROMAS akan adakan satu pencerapan di

Lokasi    : Sebelah Padang B, Dataran Shah Alam, Selangor D.E

adik jazlan jangan lupa hadhir ya. selepas itu bolih lah tulis experience disini.

JOM ramai2 cerap meteor Leonids. Jangan lupa bawa Tikar dan Bantal dan pakai losyen ubat nyamok.


cheers

[Jazlan]

Strong Leonid Meteor Shower Peaks Early Tuesday Morning

One of the best annual meteor showers will peak in the pre-dawn hours Tuesday, and for some skywatchers the show could be quite impressive.
The best seats are in Asia, but North American observers should be treated to an above average performance of the Leonid meteor shower, weather permitting. The trick for all observers is to head outside in the wee hours of the morning – between 1 a.m. and dawn – regardless where you live.
The Leonids put on a solid show every year, if skies are clear and moonlight does not interfere. This year the moon is near its new phase, and not a factor. For anyone in the Northern Hemisphere with dark skies, away from urban and suburban lighting, the show should be worth getting up early to see.
"We're predicting 20 to 30 meteors per hour over the Americas, and as many as 200 to 300 per hour over Asia," said Bill Cooke of NASA's Meteoroid Environment Office. Other astronomers who work in the nascent field of meteor shower prediction have put out similar forecasts.
Urban dwellers and suburbanites will see far fewer, as the fainter meteors will be drowned out by local lights.
Behind the Leonids
The Leonids are created by the comet Tempel-Tuttle, which passes through the inner solar system every 33 years on its orbit around the sun. Each time by, it leaves a new river of debris, mostly bits of ice and rock no bigger than a sand grain but a few the size of a pea or marble.
Over time, these cosmic streams spread out, so predicting exactly what will happen is difficult.
"We can predict when Earth will cross a debris stream with pretty good accuracy," Cooke said. "The intensity of the display is less certain, though, because we don't know how much debris is in each stream."
When Earth plows into the debris, the bits hit the atmosphere and vaporize, creating sometimes dramatic streaks of light and the occasional fireball with a smoky-looking trail that can remain visible for several minutes.
The Leonid stream is moving in the opposite direction of Earth, producing impact speeds of 160,000 mph (72 kilometers per second) – higher than many other meteors.
"Such speeds tend to produce meteors with hues of white, blue, aquamarine and even green," says Joe Rao, SPACE.com's skywatching columnist.
How to watch
The best viewing will be in rural areas. Get out of town if you can. If you have local lights, scout a location in advance where the lights are blocked by a building, tree or hill.
Dress warmly, and take a blanket or lounge chair so you can lie back and scan as much of the sky as possible. "At this time of year, meteor watching can be a long, cold business," Rao reminds people.
Leonids can appear anywhere, but if you trace them back, they all point to a hub, or radiant, in the constellation Leo – hence the name.
Give your eyes 15 minutes to adjust to the darkness. Then give the show at least a half-hour. The hourly rates stated above typically come in bursts, with lulls that may test your patience. No special equipment is needed. Telescopes and binoculars are of no use because meteors move too quickly.
When to watch
Earth will pass through one of the denser debris streams at around 4 a.m. EST (1 a.m. PST) Tuesday. If you have only an hour or less to watch, center it around this time. Leo will be high in the sky for East Coast skywatchers, putting more meteors into view. In the West, Leo will be low in the eastern sky at this time, so fewer shooting stars will be above the horizon, and therefore Western skywatchers should also try to stick it out until daybreak.
Across Europe, the best bet is to watch anytime between 1 a.m. and daybreak local time.
The planet will pass through an even denser stream later, just before dawn Wednesday in Indonesia and China, but that show won't be visible from North America because it will be daytime here.
One truth about the Leonids: They always produce, and they sometimes produce spectacular, unforgettable fireballs.

Assalamualaikum WBT

Sedikit laporan cerapan Leonids di Teluk Kemang awal pagi tadi:

Setelah mengikuti cerapan Hilal Zulhijjah pada sebelah petang semalam (17hb), yang mana saya dan Pak Aziz gagal menjejaki Hilal akibat awan tebal, beberapa daripada rakan2 FO telah memlepakkan diri sehingga awal pagi tadi di lokasi cerapan baitul hilal Teluk Kemang untuk mengejar meteor Leonids pula.

Yang hadir ialah saya, Pak Aziz, William dan 4 rakannya dari UM, Fizah dan Warid (pasangan combo dari UPM), Ustaz Shamsul dan Ustz Ramli dari Jbtn Mufti Negeri Sembilan. Dan juga uncle Pak Guard yang setia menunggu bersama-sama kami.

Sekitar jam 10 PM, kami dapati langit terbuka sedikit dengan Musytari, dan buruj seperti Taurus dan M45 jelas kelihatan. Nampak gaya macam malam yang bagus.

Namun, selepas balik dari minum malam, kami dapati langit tutup kembali.

Disebabkan cuaca tidak mengizinkan, ada di antara kami ambil kesempatan untuk lelapkan mata sekejap.

Menjelang 2 AM, langit mula terbuka sikit demi sikit. Kawasan buruj Orion, Taurus, Auriga dan Gemini di utara mula jelas kelihatan. Marikh kelihatan terbit di timur. Sementara langit selatan, Canis Major dan merentasi ke Canopus jelas kelihatan. Kawasan lain agak berawan.

Maka, bermula sesi intai intai meteor di celah-celah awan. Pada permulaan, kadar kemunculan agak perlahan. Namun menjelang jam 3 AM, tiba-tiba semakin banyak yang kelihatan. Ada meteor berkembar, kebanyakkannya yang bergerak pantas.

Namun, ada satu yang menarik perhatian kami semua. Sebuah fireball, yang bergerak berlawan arah dari radiant Leonids, bergerak dari kawasan Orion ke Canis Major. Ia sungguh terang dan bergerak cukup perlahan, sehingga membolehkan orang lain yang sedang pandang di kawasan langit yang lain, sempat menoleh dan melihatnya. Ia meninggalkan kesan yang kekal sekitar 2-3 saat. Dan bagi saya, paling menarik ialah pergerakkannya tidak lurus, tapi seolah-olah beralun-alun ke kiri kanan (nampak spt graf sinus).

Namun, menjelang kemuncak jam 5.30 AM, awan nipis semakin menutupi langit, dan menyukarkan kami melihat banyak meteor. Observasi kami tamat menjelang azan Subuh.

Secara purata, sekitar 58 meteor berjaya dicerap dari jam 2AM sehingga 5.45 AM. Tidaklah seperti yang kami harapkan, namun jumlah yang cukup menarik untuk dibuat kenang-kenangan.

Kena tunggu gambar-gambar yang diambil oleh William. 

Dikatakan ini ialah aktiviti terakhir di Baitul Hilal, Teluk Kemang sebelum ia dirobohkan untuk pembinaan balaicerap baru. Terlupa pulak nak bergambar kenang-kenangan pada pagi nanti... ngantuk punya pasal! 

Bring on .. Geminids!

untuk geminids....saya akan mencerap dri kampung halaman....di kelantan.
