Lunar X - 2018 Start Times

Recommended Posts

2018 Lunar X Predictions (approx "start times"):


Using Werner (1.2 Sun Alt) with coordinates of:

LAT      -28.0

LON     3.3


Date                Time           Sun Angle at the X at this time


01/24/2018    0442UT          -.975 @ X

02/22/2018    1807UT          -1.025 @ X

03/24/2018    0657UT          -1.064 @ X

04/22/2018    1913UT          -1.082 @ X

05/22/2018    0702UT          -1.079 @ X

06/20/2018    1837UT          -1.054 @ X

07/20/2018    0614UT          -1.010 @ X

08/18/2018    1809UT          -0.956 @ X

09/17/2018    0632UT          -0.920 @ X

10/16/2018    1930UT          -0.901 @ X

11/15/2018    0859UT          -0.903 @ X

12/14/2018    2246UT          -0.935 @ X


Average = -.0.992 @ X


Someday, when I have time, I will use Sun angle at the X of -1.000 to predict the start of event.  Either way, the times are very close as the start of the event which is somewhat subjectional...

I'm having some trouble finding the right time to try and observe this..


Am I missing something or are there some very different opinions on when this event occurs? EarthSky says you can see the Lunar X four hours around the first quarter. I saw on another source it was 2 hours before first quarter..


Heavens Above tells me first quarter in my location is around 10:30pm tonight and I live in the UK. So according to the times posted on this thread.. Ive already missed the Lunar X as it was at 0442 this morning.. I'm rather confused. Any help would be appreciated.

      No extraordinary images for this lunation, because of the turbulence and the use of infrared filters.
      Here are some images of the 24th, I am working on those of the 25th which will be of the same style.
      Clear skies.

      Just a quick enquiry ... was strolling the lunar surface on Iroc and bumped into this area of florescence on the lunar surface.

      Any thoughts anyone? (Co-ordinates at bottom of screenshot if you want to get better definition from original website).
      Was struggling to see clear heavy impact crater that would account for the wide spread of surface debris?
      Didn't think it was image flare - not expert on that so could be wrong - but noticed on RHS there appears to be traces of surface debris scatter?
      It almost seems like someone threw a very low velocity ‘flour bomb’ at the surface of the Moon?🤨
      Have there been mineral studies done on these areas of exceptional lunar florescence? ... I tapped the phrase into SGL’s Search ... but surprisingly it came up with ‘no results’??
