Topic: Sum/Moon Graphic

[weatherdoc]

I didn't know WD had any impact on the astronomy page. I'll have to look into WD settings, I guess. I had been trying to change WD setting back to the way I had them before I moved from VA, but the .ini and/or reg got messed up and I've not been successful fixing it [yet].

[tman1991]

I believe thats from WD - Web Files/Web Page Setup/Web Files Setup #1/ tick the "upload extra moon details".

[weatherdoc]

Yeah, I checked - it's unticked and the uploads were and are off, yet it keeps uploading a new moonicon.gif. Guess I'll have to dig into it more when I have time.

I found the problem there is a line in settings, ($jploc = './jpgraph-4.4.2-src-only/';  // relative location of jpgraph library) that I had to change from 4.4.1 to the new jpgraph location. Is running OK.  Thanks for your help. Joe

I think that you changed the Data font/color from yellow on black to black on white and that's causing WD to use a white surround on the moon image.

Is that Data font/color changed in WD?

[saratogaWX]

I don't know.  I didn't find that screen in WD.. how did you open that tab??

I based my opinion on the view for your moondetail1.gif which shows white background and black text.

That was a screen capture from https://wxdoc.info/wxastronomy.php.

In WD it seems to be created via Control Panel → Internet File Creation & Uploads → File #31 Extra Moon Details. Then click "Set" that opens the window below.

You can see that moon detail graphic in the upper right side of the window - I don't know how or where it is generated. Also the "Use these setting" switch is "Off".

And the Extra moon details and Moon icon files shouldn't be created nor uploaded since they have red dots:

I don't know how or why WD keeps uploading these three image files.

Thanks.

Here's what mine show:

Here's a brief in-flight progress report on an upcoming 3.60 release of sunposa.php:
1) it supports display of southern hemisphere locations and Alaska/Hawaii (by remapping 0..360 Azimuth to -180..+180 for the JPGraph requirement that only ascending X values be used, and switching from Line to ScatterPlot graphs)
2) incorporates test locations around the world with displays of what is being used (so it's easier for me to debug)
3) external programs to gather USNO sun/moon for the day and the Jun 21, Sep 21 and Dec 21 official values to compare with what the sunposa generates via calculations.
4) configurable max Elevation and default color for the legends

So the problem I'm debugging right now is the Solstice and Equinox calcs v.s. USNO .. the calcs aren't even close (and at some time offsets even when close), so using (3) above to grind through that issue.  When it's resolved, I'll issue a 3.60 version on GitHub.

Happy Labor Day (to all who celebrate).

[Vasco]

You're a glutton for punishment, Ken. . . Happy Labor Day, indeed 

On the subject of southern hemisphere I did notice that /moonimg contains NH-moon00.gif to NH-moon28.gif, but SH only goes up to SH-moon27.gif 

[saratogaWX]

Forgot to add.. auditing the moonimg graphics is also on the list.

[Vasco]

Have to admit it's difficult to show detail in a 50px image. . . 

Would an svg be any better?

[Conchobair]

Many thanks for these scripts, they add some great extras to our web sites...  Ive noticed on mine that i appear to be missing the text part  http://www.midkerry-weather.com/wxastronomy.php

Everything seems to be there when i do the debug

Just missing the additional text bit below the picture

If it helps in the process for sorting out southern hemisphere issues, the times for sun and moon daily events shown on my site: kstwx.net/index.php -->Almanac -->Sun/Moon Almanac match up with the data on timeanddate.com.

[Vasco]

Just missing the additional text bit below the picture

That's only produced by Weather Display.

[Conchobair]

  ah that would explain it then

[Vasco]

When it's resolved, I'll issue a 3.60 version on GitHub.

Trivial suggestion: spell out "Sun azimuth", as is done with Sun and Moon "elevation"?

[saratogaWX]

Suggestion noted.. Only English uses the 'Sun AZ' abbreviation .. all other languages use the long format.
I'll add it to the list...

I've been off on a 'side quest' to get better moonimg images.  Here's what I've done so far:

I grabbed images from NASA for a full month of views at 3 hour intervals in a mp4 file.
Source URL for the MP4 file:

  https://svs.gsfc.nasa.gov/4310/

Credit: NASA's Scientific Visualization Studio
Visualizer: Ernie Wright (USRA)

It was downloaded as media1.mp4, then processed by

   https://mp4-to-gif.utils.com/

to create an animated GIF, then the animated GIF was processed by

  https://ezgif.com/split

to extract the individual 1920x1080 frames as separate images.

The images were renamed from 'frame_nnn_delay-m.mms.gif' to 'moon_nnn.gif'
where 'nnn' is the frame number.

Per NASA docs:
  This short looping animation shows a complete cycle of lunar phases.
  The view is geocentric, lunar north up.
  The frames are at intervals of 3 hours, with a total length of 236 frames representing a synodic month of 29.5 days.
  To find the frame number corresponding to a particular age in days, use the formula

  frame number = ( days × 8 ) + 1

Then using that formula, days=0..29 images were selected and reprocessed by PHP GD to produce the ,/moonimg/
50x50 transparent gif images (using gen-moon-images.php)

Note: the Southern Hemisphere images were created by rotating the Northern Hemisphere images by 180 degrees.
See https://earthsky.org/moon-phases/do-we-all-see-the-same-moon-phase/ for why this works.

The comparison of the old v.s. new images is attached.

As an aside, I noticed the original Bashewa moon images were based on the Southern Hemisphere moon view for the Northern Hemisphere and rotated for the Southern Hemisphere.  The NASA source images are all Northern Hemisphere.

I'll release the updated images with the 3.60 release.

Wrapping up the side quest.. now back to debugging the solstice/equinox graphs.

[Vasco]

Wow!

[saratogaWX]

Ok, y'all can play with the new images if you like.  Unpack the attached into your moonimg/ directory and upload for a completely new set.
Too bad that today is New Moon.. so what you'll see is the black circle.. have to wait a few days to see the crescent start.

I see we also got a bonus: WxSpace. I presume all these scripts are just uploaded, and wxspace.php added to flyout-menu?

[meteosanjuan]

I already knew that for a clumsy like me it wasn't going to work the first time. I have unzipped respecting the folder order as is on my website.
I have configured some parameters according to the readme and weather display according to Ken's image, but I cannot see Sun/Moon Graphic

https://www.meteosanjuan.com/wxastronomy.php

https://www.meteosanjuan.com/sunposa.php?debug=y

Multiple errors are generated
Maybe it's because of the folder configuration on my server.
Please help. Thank you

Simple.. you used your national format (comma decimal) for lat and long (lat='37,360883', lon='-6,030507')
For PHP, you have to use period decimal format (lat='37.360883', lon='-6.030507')
Change that in Settings.php

$SITE['latitude']        = '37,360883';    //North=positive, South=negative decimal degrees
$SITE['longitude']        = '-6,030507';  //East=positive, West=negative decimal degrees

to

$SITE['latitude']        = '37.360883';    //North=positive, South=negative decimal degrees
$SITE['longitude']        = '-6.030507';  //East=positive, West=negative decimal degrees

That will also fix any issues with wxquake.php (and other scripts that use maps)

wxspace.php ?? -- that's not in my sunposa distribution, but the images could be used anywhere the moon graphic (based on moon age in days) is needed.

For those who are likely with too much time on their hands, I have posted the FULL SIZE 999x997 gif images
here:  https://saratoga-weather.org/moonimg-lg.zip  (11.4MB .zip)
and the full set of NASA images (1920x1080) non-transparent/black background
here:  https://saratoga-weather.org/moonimg-NASA.zip  (43MB zip)
and the new moonimg set
here:  https://saratoga-weather.org/moonimg.zip (137KB .zip)
Enjoy!
