Dr Ashraf Shaker, head of the astronomical department at the National Institute for Astronomical and Geophysical Research, said in a statement to the Middle East News Agency on Sunday that the moon will reach the stage of completion at two and two minutes into the evening of today and will have cut off half of its orbit around Earth during that month.
He explained that it will be visible alongside the planets Saturn and Jupiter, even before sunrise at dawn the next day, pointing out that the August full moon is known to American tribes as (the sturgeon moon ) because this time of year makes it easier to fish for large sturgeon in the Great Lakes.

He added that astronomy defines the season as the period of time between the solstice and the equinox, or vice versa, and each season – winter, spring, summer or fall – lasts three months and usually has three full moons, with an interval of about 30 days, and since the full moon lasts for a month, last June came a few days after the summer solstice, so we will see four full moons this summer, which will end with the autumnal equinox of next September.

This will be caused by atmospheric conditions, including water droplets in the air or certain types of clouds, or particles ejected into the atmosphere is also due to volcanic ash and smoke.Blue moons are also created in images using special blue filters for cameras or in image processing software.
He pointed out that in general, the designation of blue moons is issued every 2-3 years, as the last blue moon was on October 31, 2020 – coinciding with the meeting of Mars at that time, and coincidentally, the This year’s blue moon will appear near planets again, but this time Jupiter and Saturn will use the blue moon designation again in August 2023.
