Jumadal Awwal Waxing (NEW) Crescent Observation Results

So far, the earliest sighting of the crescent -after sunset- was on Tuesday 06 May 2008 from Indonesia.

Monday 05 May 2008:

  • Pakistan: Not Seen: ICOP member Mr. Muhammad Sultan Alam said: "On my request, today i.e. on May 5, 2008(Monday, 28 Rabee-uth-thani 1429 in Pakistan), many members of personal moon sighting committees of our institute "JAMIA-TUR-RASHEED" and my many friends tried to sight the moon all over the Pakistan but they could not sight the moon, as it was expected tonight that moon could not be sighted in Pakistan. Reporters are as follows:
    1. Maulana Mufti Habibullah + one scholar ("JAMIA-TUR-RASHEED", Ahsanabad, Karachi, Sindh. sky was polluted)
    2. Maulana Waqqas + 3 ulama (Nazimabad 4, Karachi, Sindh. Sky 8 degrees polluted)
    3. Maulana Mubashshir + some persons (Abbotabad, N.W.F.P. sky was partially cloudy)
    4. Maulana Shaukat (Swabi, N.W.F.P. sky was cloudy)
    5. Maulana Khushtar (Hyderabad, Sindh. sky was polluted.)
    6. Major Nasir + one person (Karachi, Sindh. sky was polluted)
    7. Maulana Abdul-Qahhar + one scholar (Pishin, Baluchistan. sky was cloudy)
    8. Maulana Abdul-Hakeem (Texela, Punjab. sky was clear)
    9. Maulana Shafee-ullah + some persons (Kohat, N.W.F.P. sky was cloudy and rainy.)"

  • Germany: Seen: ICOP member Mr. Martin Elsaesser said: "Our attempt to image the crescent around conjunction was quite successfull. We captured it just 5 minutes from conjunction. Some hours earlier we still saw a 90° arc, at less than 5° elongation. Some details and images can be found here: ( http://www.mondatlas.de/other/martinel/sicheln2008/mai/mosi20080505.html ). The imaging techniques used can definitely be improved to a near real-time experience. Also, the filters used this time captured some visible light, too. That might be of interest to someone." Note From ICOP: This crescent was seen by CCD imaging -not by direct visual observation- and it was done before sunset, thus it might not be valid for some Muslim groups as accepted sighting of the crescent to start the new Hejric month.

  • UK:
    1. Cloudy: ICOP member Mr. Sulayman Gani said: "The sighting of the Hilal was attempted by the two us from the roof of Balham Masjid. The Western Horizon was cloudy. The Hilal was not seen."

    2. Cloudy: ICOP member Mr. Abdurrashid Ayoubi from Kettering said: "Moon not sighted - cloudy horizon. Today (Monday) the moon was just over 18 hours old at sunset and so would have been difficult to observe by naked eye."

  • USA:
    1. Cloudy: ICOP member Mr. Milad Ali Ershaghi from (Claremont, CA) mentioned that it was totally cloudy.

    2. Cloudy: ICOP member Mr. Jim Stamm from (Tucson, AZ) said: "We tried to view the crescent for a few minutes after sunset through thin cloud and dust, before thick cloud covered the Moon."

Tuesday 06 May 2008:

  • Indonesia: Seen: ICOP member Mr. Mutoha Arkanuddin said: "On Tuesday evening 6 May 2008 our groups who organize by Indonesian Crescent Observation (ICO) have done sighting the crescent in many place of Indonesian Region. My team from Parangkusumo Beach who have 30 persons not success to see the the crescent because the western horizon was totally clody like the another teams in another places. However one of the teams who lead by Abdoel Moeid from Gresik (East Java) was success seen and taken the picture of the crescent.

    Observation report data:
    Location : Gresik, Indonesia

    2. Seen: ICOP member Dr. Muhammad Afifi al-Akiti from Oxford said: "Positive sighting in Oxford. The two of us sighted the Jumada al-Ula crescent at our usual site at the end of the 29th day of Rabi' al-Akhir (Tuesday, 6 May 2007). We sighted the crescent at 21.50 (position: approximately 310 degrees West; altitude around 10 degrees). The horizon was clear on the western horizon and the orientation of the crescent was 150 degrees. This positive sighting means that the first day of Jumada al-Ula in the UK is tomorrow, Wednesday, the 7th of May. Allahu akbar, hilAlu khayrin wa-rushdin x3!"

    3. Seen: ICOP member Mr. Muhammad Dar mentioned that he was able to see the crescent by naked eye.

    4. Seen: ICOP member Mr. Qamar Uddin said: "I was easily able to sight the crescent moon (Hilal) from York (UK) today (Tuesday, 6/5/2008) after the sunset (Magrib) prayer. A lot of my colleagues from York Mosque were also able to confirm the sighting, which included Shaykh Zubair Ahmed, Professor Mohamed El-Gomati, Br Hatim Salih, Br Said Jomeen and many others. I have also received reports from many other parts of UK that a lot of Ulama and ordinary Muslims have been easily able to sight the crescent moon in large numbers. We also tried to sight the Hilal, yesterday (Monday, 5/5/2008) from York Astronomical Society (YAS), but were unable to do so even with a Meade LX200 computerised telescope (as the moon was only 8 hours old!). However, one of my YAS colleagues, Paul Burgess, promised to send me a photo of the crescent from today’s sighting, which is attached. Paul said, "Here is my picture taken at 9:40pm which shows the Moon and to the left the planet Mercury". The other details of the moon in the photo (taken with a Canon 350D handheld Camera with a 80 to 200mm zoom lens at the 200mm end, 1/8th sec at F5.6, ISO 1600) are, Location: 53:52N 1:11W, Age: 32:21 hours, Lagtime: 2:23 hours, Elongation: 19:01 Deg. The above moon sighting reports fulfil the Fiqh condition of Jamme-Gafir, i.e. on a clear sky a lot of people (50 - 500) have to sight the Hilal for it to be Shariah compliant. Therefore, the Ulama have decided that the month of Rabi-ul-Thani 1429AH will have 29 days and 1 Jamad-al-Ula 1429AH will start from Wednesday, 7/5/2008, Insha-Allah. I would like to request all UK Muslims to continue making an earnest effort to sight the crescent moon every month, which is a Sunnah of the Prophet Muhammad (PBUH) for all Muslims (and a Obligatory/Fard-e-Kifayah for the community leaders!)."

    5. Seen: ICOP member Mr. Mohammad Baig from Slough said: "On Monday 5th I thought that there was a slim but fair chance of a sighting (my personal opinion) but unfortunately western horizon remained cloudy throughout the evening. Today (Tuesday 6th), it was there in its full glory and remained visible for nearly an hour."

  • USA:
    1. Seen: ICOP member Mr. Javad Torabinejad from (Blacksburg, VA) mentioned that he was able to see the crescent by naked eye.

  • Trinidad and Tobago: Seen: ICOP member Mr. Abdurrahman Ali mentioned that he was able to see the crescent by naked eye.

When to Observe Rabee Thani Waning (OLD) Crescent ?

The geocentric conjunction (Geocentric New Moon) will occur Inshalla on (Monday 05 May 2008) at 12:18 UT.

Sighting the OLD crescent on (Monday 05 May 2008) and on (Sunday 04 May 2008) is shown in the below graph 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.

  • Iraq: Seen: ICOP member Mr. Hassan Alsabbar said: "In Sunday after sunrise in Diwaniya my city I take this picture Rabee Thani Old Crescent by use Meade telescope 10inch with Sony camera a200 DSLR."

  • Germany: Seen: ICOP member Mr. Martin Elsaesser said: "The -35h old moon could be seen from Munich, Germany through hazy clouds with the naked eye and binoculars."

  • USA: Seen: ICOP member Mr. Jim Stamm said:
    "I hadn't planned to observe this event, considering it to be trivial. Then Roger Sinnott published a piece about the time interval between opposing Moons. I thought that maybe I could follow the old crescent several hours into the day and then by observing Monday's new Moon crescent, break my old record of 33 hours 9 minutes, obtained 21 January 1996.

    This observation was anything but trivial. I wanted to use my technique for pinpointing the location of the crescent despite the prediction of a naked eye crescent - for practice, and to look for ways of improving the technique. It turns out that I needed the technique.

    There were intermittent clouds all along the eastern horizon, well up into the sky. However, my plans worked well (except for not getting a limiting magnitude), and I was pointed at the correct location an hour before the Moon would rise above Pusch Ridge.

    When the time came, I was on a cloud, but engaging the clock drive, and following the invisible Moon for ten minutes brought it to a break, and the crescent was visible. However, it was too tenuous to be seen in the finder scope, let alone with the naked eye. I followed it for 41 minutes, and the image became less and less distinct. I wasn't able to measure the extent of the crescent with any precision. This was through several deep blue breaks in the clouds. At 06:13 a.m. (local) the crescent faded from view in a clear part of the sky - before the sun rose over Pusch Ridge.

    The significance of all of this? Ever since failing to see crescents which were 20-some hours from new, while easily observing them about 17 hours from new, when other conditions like altitude, atmosphere, and elongation were similar, I have considered it a mystery. I usually attributed that mystery to looking in the wrong place, being out of focus, or observing through inconspicuous weather problems. However, I was never fully satisfied with any of those explanations. Yesterday's observation has given me a hypothesis that I have long been considering.

    I believe that the reflectance for the edge of the Moon that we are seeking when observing the crescent varies considerably, and this reflectance is more determinant with respect to visibility than the calculated width of the crescent or the calculated percent illuminated. Furthermore, I suspect that the range in this effect is significant enough to become a greater factor in observability than clear sky atmospherics. Finally, I believe that we have a good enough understanding of the Moon's topography, geology, and libration to be able to predict the reflectance.
