Partial Lunar Eclipse Will Be Visible over Saudi Arabia on Wednesday

A partial lunar eclipse will be visible from Earth early Wednesday morning, said the Jeddah Astronomy Society.

Society Director Eng. Majed Abu Zahra said the partial eclipse will be visible across Europe, much of Asia, Africa, North and South America, the Pacific, Atlantic, the Indian Oceans, the Arctic, and Antarctica.

The eclipse will last for one hour and three minutes, from 5:12 am to 6:15 am Saudi time. It will be the only local lunar eclipse of 2024, he added.

"The eclipse will begin simultaneously across all regions of Saudi Arabia as the full moon enters Earth's shadow at 5:12 am. The moon will then traverse from west to east in Earth's shadow, following its natural orbital path," he explained.

"The eclipse will reach its maximum at 5:44 am, with 3.9% of the moon's surface covered by Earth's shadow. After this peak, the moon will set in conjunction with sunrise in various parts of Saudi Arabia. It may appear reddish-copper or orange during this time, due to its proximity to the horizon and atmospheric effects, rather than the eclipse itself," he said.

Globally, observers will witness the moon gradually emerging from Earth's shadow until the partial eclipse ends and the moon's full illumination returns by 6:15 am.

Abu Zahra said the moon will be at perigee (the point in the moon orbit at which it is nearest to the earth) during this eclipse, which will make it appear larger. At the eclipse's peak, the moon's apparent diameter will be 6.7% larger than average, marking it the second supermoon of 2024.

Because it is close to the autumn equinox, it is also called harvest moon.

The partial lunar eclipse can be easily observed with the naked eye, without special equipment. However, binoculars or a small telescope can provide a clearer view of the moon's details.

Unlike solar eclipses, lunar eclipses do not pose any risk to the eyes, so no special precautions are necessary.

French Scientists Find New Blood Type in Guadeloupe Woman

A French woman from the Caribbean island of Guadeloupe has been identified as the only known carrier of a new blood type, dubbed "Gwada negative," France's blood supply agency has announced.

The announcement was made 15 years after researchers received a blood sample from a patient who was undergoing routine tests ahead of surgery, the French Blood Establishment (EFS) said on Friday.

"The EFS has just discovered the 48th blood group system in the world!" the agency said in a statement on social network LinkedIn.

"This discovery was officially recognized in early June in Milan by the International Society of Blood Transfusion (ISBT)."

The scientific association had until now recognized 47 blood group systems.

Thierry Peyrard, a medical biologist at the EFS involved in the discovery, told AFP that a "very unusual" antibody was first found in the patient in 2011.

However, resources at the time did not allow for further research, he added.

Scientists were finally able to unravel the mystery in 2019 thanks to "high-throughput DNA sequencing", which highlighted a genetic mutation, Peyrard said.

The patient, who was 54 at the time and lived in Paris, was undergoing routine tests before surgery when the unknown antibody was detected, Peyrard said.

This woman "is undoubtedly the only known case in the world," said the expert.

"She is the only person in the world who is compatible with herself," he said.

Peyrard said the woman inherited the blood type from her father and mother, who each had the mutated gene.

The name "Gwada negative", which refers to the patient's origins and "sounds good in all languages", has been popular with the experts, said Peyrard.

The ABO blood group system was first discovered in the early 1900s. Thanks to DNA sequencing, the discovery of new blood groups has accelerated in recent years.

Peyrard and colleagues are now hoping to find other people with the same blood group.

"Discovering new blood groups means offering patients with rare blood types a better level of care," the EFS said.
