Is it possible to add moon info for "lunatics" :) Simon Brown <simon@...>, 27 Eki 2022 Per, 08:44 tarihinde şunu yazdı:

Could be done, what would you want to see? I think I've seen this on EME programs.

For what it’s worth, some limited lunar data are already available. If the ‘Sub-lunar’ box is checked in the upper toolbar, the current position of the moon is shown on the map. If you move the mouse pointer to the moon, the information box over the moon will display the great-circle bearing to that portion of the Earth where the moon is directly overhead.
Yes, other information may be useful (time of moon rise/set for your home QTH, phase, declination, elevation, etc.), but some of the desired information may already be available. Good luck.

FWIW,.
The info I have is: Phase, Age of current cycle, Illuminated fraction, Distance from Earth, lat/lon, Phase name, Zodiac name.

Thanks Simon. That would probably cover most of the needs of an EME user. Add azimuth and elevation and the list would be complete.
There is a useful app available for smart phones (both Android and Mac/iOS are supported) called LunaSolCal. It shows all of the data for both the moon and the sun for any location of interest. Interested users can find it in the app store for their particular phone. A Windows version is also available, but I haven’t tried it yet.
I only point this out to provide some insight as to other data elements that potential users would find of interest. As for lunar information, LunaSolCal provides time and azimuth of lunar rise, set, and lunar ‘noon’, as well as phase, age/visibility (degree of illumination), date and time of next new moon and full moon, lower culmination, declination, distance, date of next perigee and apogee, date and time of next lunar eclipse, etc.
Thanks for such a great program as Simon’s World Map, and for your willingness to make it even better by responding to user requests. Thanks and 73 Simon.

To me elevation, azimuth, declination, moonrise, and moonset are all we need. Doppler is a plus.

Um, I would think that a very useful tool would be a Moon grey-line sort of display. All places that can see it have one faint color overlay and all other places a darker overlay when it is enabled. AND that could turn off the Sun display, perhaps. I suspect the Moon does not care much if the Sun is up. (But, that big noise radiator up there might mask the Moon bounce, of course.) {^_-} On 20221027 03:58:41, Ken Sejkora

Ken, is there a chance you could make the font somewhat larger? Some folks have eyes that have aged out of their warranty period. {o.o} On 20221027 04:31:56, Ken Sejkora

I think Simon might have a point. Unless I’m missing something, I think the only parameters one would absolutely need to know to aim an antenna array for EME communication would be the azimuth and elevation of the moon relative to one’s home QTH. Obviously, moonrise and moonset are critical to determine if the moon is even visible. In addition to knowing those elements at the home QTH, knowing those parameters at a potential DX location would also be helpful to determine if EME with that location might even be feasible.
I’m not sure what benefit knowing the declination provides. Granted, it lets one know if the plane of the moon orbit is north or south of the Earth’s equator, but the overall effects of declination would be reflected in the azimuth and elevation readings for any given point in time. Declination might be nice-to-know information, but I’m not sure if it is need-to-know information.
Please enlighten me if my assumptions are incorrect. Everyone have a great day. 73

Hi Simon,
here is a good summary of the moon parameters with respect to EME:

In the crudest sense if elevation is below 0 degrees forget communicating with the Moon. A little less crude might be elevation below 5 degrees to avoid some of the multipath artifacts. And more refined would be an ability to work from a 360 degree photograph from the antenna site so if the elevation hits an obstacle shown in the picture it's noted to the operator. (Fun job for somebody masochistic enough and complete-ist enough to actually enjoy torture.) The "below X degrees is MUCH easier and can implement inside even fairly distracted operators' minds. {^_^} On 20221028 06:07:11, Ken Sejkora

Have spent a few days looking at moon information - getting declination and RA very accurately isn't easy, I've compared to a couple of well-known websites and I'm a bit out but these websites don't agree with each other!
Anyway, attached is a screenshot with some info. Position, scaling, moon image etc. being added.

Hi Simon As a definitive check, JPL Horizons site is probably the best reference. Yes, moon elevation below the horizon is useful, as EME is possible down to about -0.9 deg elevation owing to atmospheric refraction. We used this 'extra' window when working ZL on 10GHz from Start Point in Devon a few years back. 73 Charlie DL3WDG On Sun, 30 Oct 2022 at 07:11, Simon Brown <simon@...> wrote:

Ah,
Good to know. Didn't find the moon info with a quick look, do you have a link to current data?

Hi Simon Unfortunately the site doesn't have a current value. You have to go through a little pain to enter your location and then request an Ephemeris table (selecting the wanted parameters beforehand) and then running a current one. For accurate current data, WSJT-X uses the orbital models same as JPL. Also PSTRotator outputs very accurate results in real time. Charlie On Sun, 30 Oct 2022 at 07:39, Simon Brown <simon@...> wrote:

Hi,
Thanks - WSJT-X is the clue, I'll look at the source to see why the values are a bit different to mine. Declination difference is 0.5 degrees and I'm using a high-precision model so I must be doing something stupid.
