Meteor shower 'fails to impress'

Jakarta(BBC News)-Stargazers who stayed up throughout the night to witness what was expected to be an intense meteor shower were left disappointed.

The Leonid meteor shower, the best views of which were to have been from Asia, was largely obscured by cloud.

The shower was caused by tiny high-speed particles from the tail of Comet 55 P/Tempel-Tuttle, which was last in the vicinity of the Earth in 1998.

Nasa had projected there would be up to 300 meteors raining down every hour.

On a typical night there are about eight per hour. In many of the viewing hotspots, however, hopeful visitors were let down by the weather.

Reports from the Philippines, Nepal and India were of cloudy conditions blocking a view of the night sky.

But there were a few stories of stargazing success.

Up to 1,000 people who camped out in a car park on the outskirts of Bangkok in Thailand spotted 52 meteors over several hours.

One group of amateur astronomers in India at the Siriska wildlife sanctuary, south of New Delhi reported counting 78 during a four-hour period.

"There was no moon in the sky, which is good for observation," Yogeshwar Kanu Aggarwal, a member of the Space Science Popularization Association of Communications and Educators, told the Associated Press news agency.

"We could see flashes of light for almost 10 seconds as bright as star Sirius."

North American observers stayed up from the early hours of the morning until dawn on Tuesday 17 November to view the shower's peak.

Lapan to launch Orari satellite next year

Jakarta (ANTARAnews) - The National Space and Aviation Agency (Lapan) and the Indonesian Radio Amateurs Organization (Orari) is set to launch an Orari satellite in 2010, the organization`s chief Sutiyoso said.

Orari played a bigger role in keeping the Unitary Republic of Indonesia intact through broad and strong communication networks, he said when installing the executive board of Orari chapter in South Kalimantan on Friday.

Aware of the greater role, the former Jakarta governor said Orari is cooperating with Lapan to launch an Orari satellite to expand its networks to remote areas in the country.

"Communication does not guarantee victory in a battle. But it is difficult to win a battle without communication. That`s why Orari plays a greater role in fostering land, sea and air communications," he said.

In fact, Orari had so far served as an alternative communication means in case of massive disasters in the country, he said referring to an 8.9-magnitude undersea earthquake and the subsequent tsunami devastating Aceh on December 26, 2004 when all communication means were paralyzed for a few days.

Orari was the only communication means in the region at that time to report any developments to the rest of the country, he said.

He said Orari once again became the only alternative communication means when a powerful earthquake rocked West Sumatra province on September 30 this year.
Orari was a big and solid organization although it never relied on government financial assistance, he said.(*)
