Namun demikian, ada satu laporan terlihatnya hilal pada petang hari Rabu, 17 Januari 2018 yang diperoleh dari satu orang pengamat di wilayah Amerika Serikat. Sebagaimana laporan di situs moonsighting.com, Mr. Norm Margus melaporkan berhasil melihat hilal dengan bantuan teropong binokuler.

Mr Norm Vargus from Mt. Wilson, CA reported: The crescent moon was seen by optical aid only on Wednesday, January 17, 2018. Exact location: The main parking lot at Mt. Wilson Observatory, CA, USA 1700m above sea level. The parking lot offers expansive views to the west and is an excellent location for viewing sunsets and new moons. Exact time: It was first seen in binoculars at 5:33 pm and followed in a spotting scope and binoculars until 5:45 when it sank into clouds. Altitude of the moon: The horizon was indistinct with clouds and the moon’s height was not measured. It’s height was calculated to be about 4º above the horizon. Location of the moon: The moon was found above and to the left of the sun, but 20 minutes after sunset. Mooncalc 6.0 showed it to be nearly directly above the sunset point at the time of first sighting. Orientation of the moon: The moon faced the 5 o’clock position. The tips of the crescent extended from the 3:30 to 6:15 positions. The arc was very small due to low contrast. Crescent movement: The moon set down and to the right. Sightings was with optical aid by one adult, me. The contrast of the moon was poor with the thin clouds covering the horizon and it could not be spotted naked eye.
