Sun position plugin
A question: at noon I see the azimuth at zero degrees. Is it correct?
I thought the azimuth defined as
a horizontal angle measured clockwise from the north
not from the local meridian.
... a second thought ... are you in the southern hemisphere?
It could be because in Astronomy the azimuth may refer to the South, instead of North (but I am not an astronomy specialist). The South reference was used in former times, but today this is not clear because sometime it refers to North and sometime still to South....
-See Astronomy section-
With this plugin if you take a point far in south hemisphere at near 12:00Z, you see the azimuth of the sun close to 180°. It varies from 180° to -180°, not from 0° to 360°, as shown in this example (-172°):
So it’s different from what is used in navigation technic.
This is the best link that explains this convention.
BTW in traditional astronavigation or celestial navigation, the solar azimuth is measured from the north...
I am trying to install sun position plugin, but despite it says that plugin was installed, it does not appear menu. i tried it on my laptop (windows) and iPhone. Do you have an idea what might be the problem?

I tried too, and it appears it only works on dektop as one-shot action, i.e. only when left panel info is displayed (screenshot); on closing left panel, next click on map returns usual results...
@Oilyan @vsinceac I'm not sure what the problem is. I just tried it again and for me, it still works for me (both on PC and on mobile). You should be able to find the option to open it in the context menu (right-click on the map on PC; long tap on the map on mobile). You can move the picker afterward as well, just make sure not to clock on a city label as that opens the weather forecast and closes the plugin pane.
Am I right in thinking this doesn't work on the iPhone app?
I went to www.windy.com/plugins on my phone browser and searched for windy-plugin-sun-position, then installed it, but when I log in on the browser it switches to the app since I am already logged in there. On my app the plugin doesn't appear anywhere.
Would appreciate any ideas. Thank you
The plugins are not available in the App.
They are available in a mobile browser (chome or safari). Type or paste: https://www.windy.com/plugins/windy-plugin-sun-position in the address bar.
(With the most recent Windy app update on iOS, the app diverts the windy.com/plugins to the browser, really cool. Unfortunately it does not seem to work on Android yet)
I have just released version 0.3.2 of the plugin. The plugin was broken because the pluginDataLoader changed. I only used the pluginDataLoader for a timezone lookup. As that wasn't a good solution anyway I am now using the tz-lookup package instead. So hopefully it wont break as easily in the future.
Furthermore this update makes use of the query string: For example you can now directly open https://www.windy.com/plugins/windy-plugin-sun-position?photoSun=true&astroSun=false&moon=false to get only photography sun details.
Thanks. Maybe a bug? Should golden hour not come after sunrise?
No, the golden hour is defined as sun elevations between 6 degrees above and 4 degrees below the horizon. So the golden hour does start before the sunset and also continues until after sunrise. The entire time range in orange is the Golden Hour. Also, in very high latitudes the entire day might be "golden hour" as the sun never reaches higher than 6 degrees above the horizon.
(Also see the screenshot in the original post, it was always this way ;) )
