Dubai satellite captures image of Ramadan crescent 2018

LONDON: An image of the Ramadan crescent was captured by the Mohammed bin Rashid Space Center’s (MBRSC) remote sensing satellite DubaiSat-2 this week.

The image, released by MBRSC, was taken by rotating the earth observation satellite, a maneuver that took weeks of planning and hours of painstaking alignment.

Taken with a roll tilt angle of 0 degrees and roll pitch angle of 79.63 degrees, the final image was post-processed to highlight the crescent aspect of the moon.

DubaiSat-2 orbits Earth at a speed of 7.5 kilometers/ second, completing each total orbit of the planet in 90 minutes. Its camera images Earth from an altitude of some 600 kilometers at a resolution of 1 meter per pixel, providing world class images

The start of Ramadan is determined by the lunar calendar which follows a 29- or 30-day cycle determined by the cycle of the moon. Muslims anticipate the end of Shaaban, the month preceding Ramadan, by watching for the absence or presence of the crescent moon, which respectively indicates the continuation of Shaban or the beginning of Ramadan. 

Sighting of the Ramadan crescent can be achieved by three methods: through telescopes and binoculars; using astronomy; or viewing with the naked eye.

Sudan's top opposition rejects strike call in protest rift

KHARTOUM: Sudan's main opposition group and supporter of the protest movement on Sunday rejected its call to stage a two-day general strike, in the first sign of a rift within the movement negotiating the launch of civilian rule.
Talks between leaders of the umbrella protest movement, the Alliance for Freedom and Change, and army generals who seized power after ousting autocrat Omar Al-Bashir last month are deadlocked over who should lead a new governing body - a civilian or soldier.
In a bid to step up pressure on the generals, the protest movement has called for a general strike starting Tuesday, but the National Umma Party, a key backer of the movement, rejected the measure.
"We reject the general strike announced by some opposition groups" in the Alliance for Freedom and Change, the National Umma Party said in a statement.
"A general strike is a weapon that should be used after it is agreed upon by everybody," Umma said.
"We have to avoid such escalated measures that are not fully agreed."
The National Umma Party led by former premier Sadiq Al-Mahdi said any such decision should be taken by a council of leaders of the protest movement.
Such a council was still not in place and "will be composed in a meeting on Monday", it said.
It was Mahdi's elected government that Bashir, who himself was deposed on April 11, toppled in a coup in 1989.
In a recent interview with AFP, Mahdi warned protesters not to "provoke" the army's rulers as they had been instrumental in ousting Bashir.
