Wedensday 18 February 2015

Thursday 19 February 2015

According to the Universal Hejric Calendar (UHC), which is based on the calculated crescent visibility, the start of this month in the Eastern Region will be on Friday 20 February 2015 and in the Western Region will be on Friday 20 February 2015. Kindly notice that the UHC is a pre-calculated calendar, which adopts a certain criterion to start the new Hejric month. Your country/organization might adopt different criterion to start the new Hejric month. So it is highly advised to read the UHC website before giving any judgment.

- Results of seeing the crescent, and the first day of the month in different countries will be added here Inshalla as we receive the reports from ICOP's members. If you wish to be a member in ICOP, or to know more about it, kindly click here.

I sighted Venus high above the horizon; the crescent should have been to its lower right.  Since more clouds were moving in towards the expected crescent location, I left this site for anther location in Christiansburg, a Town a few miles to the south.  While driving, at 6:37 pm, I saw the crescent by naked eye.  I stopped by one of my sighting locations in Christiansburg to take pictures.  At this time, the crescent was very close to the clouds hugging the lower western horizon.  The horns were at 4:00 and 7:30 O'clock (4:00;6:00;7:30).  Mars was also sighted just above Venus.  I left the area at 6:49 pm prior to moonset (moonset: 7:14 pm).

United States


1 . Time of observation: Before sunrise. Seen: ICOP member Mr. Jim Stamm from Tucson City in Arizona State mentioned that the sky was clear, the atmospheric condition was superb, the crescent was not sought by naked eye, the crescent was not sought by binocular, the crescent was seen by telescope, the crescent was not sought by CCD Imaging
Mr. Jim Stamm said: "Old Moon Crescent Observation Report
======================================
Observed:   Wednesday; February 18, 2015  -  06:47 (Local)

Location (WGS 84) = Tucson (Windy Point), Arizona (USA)
   Longitude = 110.71 W
   Latitude  =  32.36 N
   Elevation =   2003 meters
   Time Zone =   -7.0 hours

Surface conditions near location:
   Temperature =   8 °C
   Humidity    =  60 %
   Pressure    =  30.1 in.

   Haze to the west, but little seen to the east.

Topocentric and local time values from “Accurate Times”:
   Moonrise (at sea level)  =  06:27
   Sunrise (at sea level)   =  06:55
   Time from new moon at   06:47   =  11 hr. 41 min.
   Moon lag time                   =     28  min.
   Relative Altitude                =    5.6  degrees
   Elongation from sun          =    6.1  degrees
   Crescent width                  =       6  arc seconds
   Illumination                       =    0.3  percent


Crescent first observed through 8” SC telescope:
   Time   =   06:45 
   Moon Altitude  =   0.9 degrees

Final observation with telescope:
   Time   =   06:47 
   Moon Altitude  =   1.3 degrees

This was a most interesting and rewarding observation.  It became a priority for Mt. Lemmon because the first sighting of a crescent under 7 degrees was made under similar conditions from the same place, and this elongation was close to 6 degrees, significantly less than the 6.5 degree elongation observed previously.

Planning was meticulous, with a couple of dry runs at the desk the day before.  The sky looked great the next morning, and the temperature on the mountain was warmer than expected.  Aligning the scope took a little longer than usual, but all of the following steps went off without a hitch.  The only element that did not cooperate was the limiting magnitude.  I was charting 10th magnitude stars, but I was only seeing 8th magnitude.  That prepared me for a negative observation.  However, I was pointed really close to the horizon - still in the “red zone,” so 10th magnitude was overly optimistic.  Only one or two of my confirmation stars showed up in the field of view.  That was OK, because I was already locked on the correct location - even two minutes earlier than planned.  Only the focus remained a little less than assured.

When the time came (06:40 a.m. local) to engage the clock drive set on lunar motion, I still hadn’t seen anything except a lot of those “false crescents”.  The physiology of the eye is diabolical, creating arced images just the size of the expected crescent.  Fortunately they were whiter than real crescents are, and they were of the wrong orientation.

Then at 06:45, after getting above the “red zone”, some of the “false” crescents began showing up in the right orientation, and at the right spot in the field of view.  They were not as bright, and much shorter in arc-length, and more importantly, they lasted long enough to see them vibrate when I tapped the telescope tube.  This still wasn’t long enough for me to confirm that I had seen the crescent, but they were multiple, periodically appearing for the next two minutes.    Taken together I was confident that my sightings were real.  I had observed a crescent with an elongation of 6.1 degrees from the sun  ....  EXCEPT  ....  the dust specks on the lens of the eyepiece showed that the crescent had moved about an arc-minute or so during those two minutes.  The movement was up, away from the sun.

The drive was set on “Lunar”, so the scope should have approximated the moon’s movement toward the sun.  That drive movement is constant, while the actual apparent velocity of the moon is variable, so I will need to determine if that factor can explain the movement in the field of view.  Also, refraction is a significant factor near the horizon, so I’ll need to determine if that could account for an arc-minute or so.  Generally, the effects of refraction should be the opposite of what I observed.  If anyone can help me out by suggesting other factors, I’d appreciate it.

Overall, the impression of this observation was that this first sighting was similar to the last sighting of some previous old moon crescents, where I would follow them up, tapping the scope for as long as possible, sometimes even observing after sunrise.

If I can resolve the conundrum of the apparent aberrant movement of the old moon crescent, and then observe tomorrow’s new moon around noon, I may be able to observe “opposing” moons of less than 30 hours.

The next day:

I set up the scope this afternoon and acquired the crescent at 1:29 local (MST;-7hr).  The first thing that I did was set the scope to follow the moon at the lunar rate.  Just like yesterday, the scope was advancing faster than the moon was across the sky.

I am embarrassed to admit that I should have considered this to begin with.  The clock drive rate would naturally be set at the moon's apparent velocity across the sky at it's median distance from Earth.  The moon would lag as it approached perihelion and advance as it approached aphelion.  The moon was lagging, the moon was close to perihelion, the moon was right where it was supposed to be.
