Rabee Awwal Waxing (NEW) Crescent Observation Results

So far, the earliest sighting of the crescent was on Monday 19 March 2007 from USA.

Monday 19 March 2007:

  • Indonesia:

    1. Not Seen: ICOP member Mr. Ma'rufin Sudibyo said: "The hilaal sighting had done in Kebumen, Central Java, Indonesia (position 7 deg 40 min S 109 deg 38 min E, mean height 21 m above sea level, time zone: GMT + 7), and March 19th 2007 at Maghrib time. Although the weather was clear, the western sky was partially closed by the cumulus clouds until altitude of nearly 10 degree above western horizon. We used naked eye and helped by calibrated-Siemens C45 internal clock for time guideline. We also used a table that contained Moon altitude versus local time, which derived from moon Calculator v6.0 (topocentric condition, geometric sunset/moonset and no refraction). Sunset has predicted at 17:50 local time, where Moon have altitude 2,20 degree, relative azimuth 3,81 degree, elongation 4,43 degree, diameter 33,36 arc min, crescent width 0,05 arc min, Moon age 8 hours after conjunction, phase 0,19 % and visual magnitude -4,4. The moonset has predicted at 17:59 local time. The sunset point at western horizon hasn't identified because hidden by cloud, also around the area where hilaal located. When Venus (visual magnitude -4,0) was seen at 18:09 local time, situation hasn't changed."

    2. Not Seen: ICOP member, Mr. Susiknan Azhari said: "The weather is good, but we can't see the hilal although moonset after sunset. In Yogyakarta (Latitude = -7,8 Longitude = 110,35) Conjungtion (Ijtima') = Monday, 19 March 2007. Time : 09.44.19 (LMT/WIB). Altitude/Irtifa'= +02 deg 00 min 26 sec. Muhammadiyah Calendar and Taqwim Standar Indonesia (Indonesian Ministry of Religion Affairs) announced that 1 Rabiul awal 1428 H is corresponding to Tuesday March 20, 2007."

    3. Cloudy: ICOP member, Mr. Mutoha MMC said: "The crescent was not seen anywhere in Indonesia because the Western sky was cloudy and the moon altitude very low (2°18') at sunset. According to Indonesian civil calendars who used the "imkanurrukyat criterion", the first day of Rabiul Awwal 1428 AH begins on Tuesday, 20 March 2007.

There were a few stars visible high up in the sky - however, much higher than where the moon would be expected to be seen. I visited Upland, Claremont, La Verne, and San Dimas, but in none of these cities was I able to see the moon. I continued looking until 8:07 PM, the moonset time obtained from the US Naval Observatory's Astronmical Applications Department website, and then returned home."

    4. Seen: ICOP member Mr. Abdul Rashid Abdullah said: "I was only visiting in the area. I was driving west bound on Interstate 10 towards Los Angeles and had just left the Palm Springs area when I first noticed the hilal. It was very faint so I looked away and then back again. I was able to observe it for at least 10 minutes while I was driving. The exact details I provided may not be so exact as I was traveling and didn't have an opportunity to write anything down, however, I did take note that the time was around 7:10 PM local time."

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

  • Germany: Seen: ICOP member Mr. Gerhard Ahmad Kaufmann said: "I wasn't prepared for any observation today, as the sky was cloudy most of the time. So I was very surprised when I looked unintentionally in the sky this evening more than an hour after sunset, and saw a very beautiful crescent with a yellowish hue, lying nearly horizontally over the western horizon. My whole family took a glance at this sight. I could have observed the crescent much earlier if I had tried, but so I only looked at it for a couple of minutes and did not notice any further observation data."

  • Nigeria: Seen: ICOP member Mr. Muhammed Ya'sin Qamardeen said: "The new Hilal of Rabiul awwal is easily sight this evening at western horizon just below shinning VENUS whichis located at about 30 degree above horizon.

ICOP Official Statement

When to Observe Safar Waning (OLD) Crescent ?

The geocentric conjunction (Geocentric New Moon) will occur Inshalla on (Monday 19 March 2007) at 02:43 UT.

Sighting the OLD crescent on (Sunday 18 March 2007) 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.

Safar Waning (OLD) Crescent Observation Results

Sunday 18 March 2007:

  • Indonesia: Seen: ICOP member Mr. Ma'rufin Sudibyo said: "The waning crescent sighting had done in Kebumen, Central Java, Indonesia (position 7 deg 40 min S 109 deg 38 min E, mean height 21 m above sea level, time zone: GMT + 7), and March 18th 2007 at Shubuh time. At that time the weather was clear and the sky was very perfect, moreover The Milky Way was seen easily. We used naked eye in observation and helped by digital camera Sony Cybershot DSC U-20 2 mega pixel without zoom for made several pictures. We also used internal clock in Siemens C45, calibrated with international time reference system served by the Telkom Co. Ltd for time guideline. We also helped by a table, which contained Moon altitude versus local time that derived from Moon Calculator v6.0 (with topocentric situation, geometric sunrise/moonrise and no refraction). This software also predicted that sunrise would happen at 05:49 local time, where Moon have altitude 14,53 degree, relative azimuth 5,05 degree, elongation 15,4 degree, diameter 33,12 arc min, crescent width 0,6 arc min, Moon age 28 hours before conjunction, phase 2,03 % and visual magnitude -5,6. Moonrise would happen at 04:44 local time. The waning crescent had seen although obscure when we was started the observation at 05:54 local time. The crescent was seen clearly since 04:58 until 05:20, when it obscured again and really unseen at 05:30 local time. Orientation of the crescent was 4 - 9. Finally, the Sun disk had started visible above eastern horizon at 05:49 local time exactly."

      Phase: 1.52%
      Width: 0.46m
      Arc Length: 75° (9.5-7)

    2. Cloudy: ICOP member Mr. Majid Marzani said: " The eastern horizon was cloudy. Thin clouds be the reason for not seeing the crescent."

  • USA: Not Seen: ICOP member Mr. Jim Stamm said:

    Location = Tucson, Arizona (USA) - Mt. Lemmon
    Longitude = 110.69 W
    Latitude = 32.4 N
    Elevation = 2210 meters
    Time Zone = -7.0 hours

    Surface conditions at time of first/last sighting at Tucson International Airport (805 m):
    Temperature = 8 degrees Celcius
    Relative Humidity = 39 percent
    Atmospheric Pressure = 1021 mb (sea level)

    Magnitude limit at 1 degree altitutde with 55 power in C-8 telescope, before onset of twilight = 8-9

    Topocentric and local time values from “Accurate Times”:
    Moonrise (at sea level) = 6:04
    Sunrise (at sea level) = 6:22
    Time from new moon at 6:14 = 14 hr. 53 min.
    Moon lag time = 18 minutes
    Relative Altitude = 3.71 degrees
    Elongation from sun = 7.36 degrees
    Crescent width = 8 arcseconds
    Illumination = .41 percent

    I was NOT able to see the crescent, even through a telescope. Haze was obvious. Even the rising sun was filtered enough to observe through the telescope.

    From my home, the mountain that I was on rises to about 7 degrees altitude in the east. When the sun pops out it is usually immediately extremely bright. Obviously this is because the thickness of the haze is much less.
