I was observing with my wife and my friend Mr. Nizar Sallam, the sky conditions were superb relative to Abu-Dhabi, since we were able to see the Sun disk until it touched the sea and even until the very last part of the disk disappeared behind the sea! However, generally speaking, the conditions were hazy with very high relative humidity! The Sun disappeared at 19:14, and we were able to see the crescent at 19:34 by 7X50 binoculars, we tried to see it by naked eye, but due to the hazy weather this was not possible! So all of us were only able to see the crescent by binoculars."

    2. Cloudy: ICOP member Mr. Muhammad Afifi al-Akiti from Oxford said: "The two of us attempted moonsighting at our usual site at the end of the 29th day of Jumada II (Sunday, 15 July 2007). The horizon was overcast and the crescent could not be sighted. We received reports of positive sightings from the East. Knowledge of these positive sightings in the East, despite not being able to sight locally in the UK, makes it sufficient for us to establish the month of Rajab for the UK to be tomorrow, Monday, the 16th of July. This is by following the default rule [dabit] in Islamic Law in this matter that whenever it is known that the crescent has been positively sighted in the East, local sighting inevitably follows, but not the other way round [mata hasalati r-ru'yatu fi l-sharqi lazima ru'yatuhu fi l-gharbi wa la-'aks]. "

  • USA: Seen: ICOP member Mr. Milad Ali Ershaghi from (Claremont, CA) said: "Local sunset time was 8:03pm and moonset time was 9:17 PM. After Salat-ul-Maghrib, I went outside to find the new crescent moon, and alhamdulillah was blessed to see it at 8:46:15 pm without the use of any optical aids, the sky still partially bright, as the sun continued to descend further beneath the horizon. From where I was situated (-117°41'59.2" longitude, +34°7'9.195" latitude), the moon was visible approximately 80°W of Magnetic North, or 67°6' W of True North. The lower right quadrant of the moon appeared illumined, and alhamdulillah it was a very beautiful sight. We completed 30 days of the month of Jumada al-thani, and begin the first of the month of Rajab on the evening of Sunday, July 15, 2007, the day of Monday, July 16, 2007)."

Saudi Claims Seeing Rajab Crescent on Saturday 14 July 2007

Although it was 2 hours and 41 minutes old as seen from Makkah, and it stayed for 14 minutes only after sunset, Saudi officially declared that this crescent was seen! We wonder if all the experienced astronomers in the world were not able to see that crescent on that day from anywhere on Earth by telescopes even from far western location, then how it was visible in Saudi by naked eye! Well, we all know that this is not the first false sighting in Saudi! Kindly find below the official statement. Thus, Saudi will look for Shaban crescent on Sunday 12 August! We must feel shamed when our officials are asking us to look for the crescent when we know that the moon will set before sunset! It is not only waste of time, but it is also disrespect to the science and our minds.

When to Observe Jumadal Thani Waning (OLD) Crescent ?

The geocentric conjunction (Geocentric New Moon) will occur Inshalla on (Saturday 14 July 2007) at 12:04 UT.

Sighting the OLD crescent on (Friday 13 July 2007) and on (Saturday 14 July 2007) is shown in the below graphs using the program Accurate Times by Mohammad Odeh according to Odeh criterion. Where:-

  • It is impossible to see the OLD crescent from the areas located under the red color. Because either the Moon on this day rises after the Sunrise and/or the topocentric conjunction occurs before the Sunrise.
  • The crescent is expected to be seen by optical aid only from the areas located under the blue color.
  • The crescent is expected to be seen by optical aid from the areas located under the magenta color. In these areas the crescent could be seen by naked eye if the atmospheric conditions are superb and the observer is experienced.
  • The crescent is expected to be easily visible by naked eye from the areas located under the green color.
  • The crescent can not be seen from uncolored areas, even though the Moon rises in these locations before the Sunrise and the topocentric conjunction occurs after the Sunrise, but the Moon is not sufficiently illuminated in order to be seen as crescent even by optical aid.
  • Kindly notice that the below graph shows the possibility of seeing the crescent from areas between 60 degrees north of Equator down to 60 degrees south of Equator.

Jumadal Thani Waning (OLD) Crescent Observation Results

Friday 13 July 2007:

  • Indonesia: Seen: ICOP member Mr. Ma'rufin Sudibyo said: "The waning crescent sighting had done in Kebumen, Central Java, Indonesia (7deg 40min N 109deg 38min E, 21 m ASL, time zone = GMT + 7) at July 13th, 2007 this morning. The sky was covered by thin cloud until altitude nearly 5 degrees and eastern horizon was hidden by haze, so we had horizontal visual range only 1 km, approximately. We used naked eye for observation, and helped by callibrated internal clock Siemens C55. We also used Moon Calculator v6.0 developed by Dr. Monzur Ahmed for obtaining a table of crescent altitude vs. local time. The waning crescent had seen obscurely when we started our observation at 05:10 local time, with altitude nearly 5 degrees. Be sides the crescent, eastern and southern sky was adorned by Mars and Achernar (alpha Eridanus) as faint point light source in altitude nearly 60 degrees, respectively. The crescent had specific arc shape but with cloudy environment we couldn't identify real orientation of the arc. The crescent was seen until 05:20 local time when it was hidden by cloud, where it had elements: altitude 8,7 degree; relative altitude 17,8 degree, relative azimuth 9,3 degree, elongation 20 degree; visual magnitude -6 and phase 3,31 %. Until we finished our observation at sunset time (05:59 local time), situation hasn't changed."

  • Iran:

    1. Seen: ICOP member Mr. Alireza Mehrani mentioned that he was able to see the crescent by naked eye.

    2. Seen: ICOP member Mr. Majid Marzani said: "The crescent was seen by naked eyes. The Sky Near The Eastern Horizon Was Clear."

    3. Kuwait: Seen: ICOP member Mr. Hussain Khushaish said: "In Kuwait on Friday mornning 13 July 2007 I saw the old crescent in the following order: Moon rise at 3:21, first seen with bino at 3:38, first seen with naked eyes at 3:39, last seen with naked eye at 4:50, sun rise at 4:57, last seen with 20*60 binocular at 5:19."

    4. Lebanon: Seen: ICOP member Dr. Raad Ahmad mentioned that he was able to see the crescent by naked eye and Dr. Ahmad mentioned that the atmospheric conditions were superb.
