Two years ago, I saw the crescent of Dhul-Qi'dah 1426 (December 2, 2005) in the same location. Although, this year, the crescent of Ramadan was very similar to the 1426 Dhul-Qi'dah crescent, but it was thinner and also 0.5° altitude less at the sunset.
By a theodolite camera, I found the crescent situation at 18:05 LT, and waited for the observation time. At 18:05 I started the observation and every 5 minutes by the theodolite, I was controlling the crescent direction. From 18:05 to 18:22, I saw a flash in the view field. For some seconds it repeated but without any fixed image. I couldn't be satisfied that I have observed the crescent. It seemed to be a curved, but because of the very appearance, I changed my mind for observing and it disappeared.
The crescent had mixed in the thin dust. It was just some seconds after 18:22, that I recognized a flash again in the view field center. After some seconds, the mentioned flash became a clear and permanent image from a thin short arc. The image started flashing but it became fix again for a longer time. I became sure that this arc is the crescent and so surprised became of the arc length shortness.
When the crescent started flashing, I couldn't see it any more. Although I continued the observation until the crescent sinked in the middle part of the thick dust, but it was futile.
