W5LUU's Moon Data for year 2010

IMPORTANT NOTICE: W5LUU has decided not to continue with his task of editing this calendar, so we could not expect a 2011 calendar. After so many years of excellent job we can only give a big thanks to Derwin and whish him all the best.  However, EA6VQ has created his own calendar of weekends and best days for EME on 144 MHz.

 

 

MOONDATA UPDATE-2010 AND RELATED COMMENTS By Derwin King, W5LUU

The best EME conditions occur when:

  1. The earth-moon distance is at the absolute minimum and
  2. The moon is in the coldest sky region along the moon path.

The effect of distance is independent of frequency, but sky temperature decreases with frequency, up to ~1 GHz and then levels out. The EME signal-to-noise ratio, in dB, is degraded, from the minimum, by a factor (DGRD, see below), which varies over hourly, daily, weekly, monthly and yearly time periods. As a guide for the basic weekend EME conditions for 2010 the W5LUU WEEKEND MOONDATA 2010 lists the DGRD, in dB, for 144 and 432 MHz, and other pertinent EME information for each Sunday at 0000 UT. Factors such as local noise, antenna beam width, side lobes, polarization, etc. can also affect the s/n ratio of moon bounce signals. Low sunspot activity in 2010 minimizes disruptive ionosphere disturbances. Good conditions will prevail.

For frequencies below 1296, 2010 will be the best EME year until 2019 or later. Some Good and Excellent days occur on weekends, but more during the week. Days listed below have a 144 MHz DGRD that is a minimum at d, day and h, hour and may last for + or - several hours.

January: 02d/ 2310h (0.18 dB) and 30d/1051h (0.02 dB)
February
: 26d/2215h (0.60dB)
March: 19d/1930h, (0.41dB)
April: 22d/1430h, (0.65dB)
May: 19d/1930h (0.68dB)
June: 16d/0233h, (0.5dB)
July: 13d/1034h, (0.25dB)
August: 09d/2056h, (0.13 dB)
Sept.: 06d/0730h, (0.23 dB)
October: 04d/1822h, (0.66dB) and 31d/0003h, (0.75 dB)
November: 27d/0534h, (0.81dB)
December: 24d/1150h, (0.63dB).
