When to Observe ?

The geocentric new Moon will occur on Friday 27 October 2000, at 07:58 UT. On this day (27 October), the program Moon Calculator by Dr. Monzur Ahmed -according to Yallop criterion- showed that the crescent will be visible by telescopes from parts of western America continents. While it is not expected to see it on this day by naked eyes. On the next day (28 October), the crescent should be visible by naked eyes from nearly every where. Consequently, arrange to observe the crescent after the sunset of 27 or 28 October. Kindly click on the below icon to see the visibility parabola as plotted by the program Moon Calculator

Results of seeing the crescent, and the first day of the month in different countries will be added here Inshalla as we receive the reports from ICOP's members. If you wish to be a member in ICOP, or to know more about it, kindly click here.

Results of Observation

So far, the earliest sighting of the crescent was on Saturday 28 October from Mauritius by Mr. Hamade Aubdoollah. On this day, the crescent was also seen from Iran, UAE, Jordan, Nigeria, Morocco, Canada, and USA.

Friday 27 October

  • Saudi: ICOP member, Mr. Saleh Al-Saab said: "The crescent was not seen, it was about three degrees above the horizon, the sky was not clear enough. Saturday is the first day of Sha'ban."

  • Jordan: The western horizon was partly cloudy.

  • USA: ICOP member, Mrs. Alphecca Muttardy said: "In the Washington, D.C. area, skies were crystal clear on Oct. 27, 2000, except for a haze along the horizon about 2 degrees high. The moon WAS NOT seen by naked eye between sunset (6:15pm) and moonset (6:45pm). In fact, NO VERIFIED SIGHTINGS from continental North America were reported to the Committee for Crescent Obervation. As the new crescent should grow larger with the passage of time, a failure to see the moon in N. America means that all claims of seeing the moon in the Middle East 8 hours earlier were incorrect. ISNA seems to be taking Sunday, October 29, 2000, as the first day of Sha'ban."

Saturday 28 October

  • Mauritius: ICOP member, Mr. Hamade Aubdoollah said: "I am pleased to inform you that Shabaan crescent was visible in Mauritius on Saturday 28th Oct 2000 and Sunday 29th Oct is InshaAllah 1st Shabaan 1421."

    • Morocco: ICOP member, Dr. Hamid TOUMA said: "I am pleased to inform you that the Crescent of Moon was seen on Saturday 28 Octobre 2000 at Rabat at 17 h 50 mn, a few minutes after the Sunset. As you know that the new moon was on Friday 27 October 2000 at 9 O'Clock 59 mn (AM) in the Moorning and in the afternoon of the same day at 18 h, just after the sunset, the Crescent was only under of 12 hours of life so it was impossible to observe it in the same day (creteria of danjon), but on Saturday at 18 h (PM) it has 34 hours of life, so it was visible very good. So the first day of Shaabane was officially in Morocco the Sunday 29 octobre 2000. Thank you."
