this bug was first reported here :
https://bugs.mageia.org/show_bug.cgi?id=32739#c9

unfortunately the .xml files of opencpn-weatherfax-plugin  need frequently to be adapted to the changes inside the internet-weatherfax providers site


and the WeatherFaxSchedules.xml file already needed to be adapted to the changes of the frequency and time of the radio fax providers
(fortunately this file seems to be up to date for some time now)

Thank you as usual for your watchful eye & work on opencpn.
Since you are effectively the maintainer of this pkg, and already working on it, assigning to you. When it is ready, please suggest how it might be tested - even if only to check that a certain file contains certain key information.

Bad news from aviationweather.gov  (a site of NOAA)

The site https://aviationweather-cprk.ncep.noaa.gov/ is discontinued
We will have to remove 
/usr/share/opencpn/plugins/weatherfax_pi/data/
WeatherFaxInternetRetrieval_Aviation_Weather.xml
from the rpm
:-(

Here is my question :
Category: Bug
Subject: https://aviationweather-cprk.ncep.noaa.gov/ not reachable

I have tried several times to go to this site https://aviationweather-cprk.ncep.noaa.gov/ to download satellite images

I could do this in january 2024 but that seems no more possible
has this address been changed ? or this site is temporarily not reachable ?

And here is the answer

Hi Philippe,

Please note that the URL for our website changed on October 16th as part of a major website upgrade. The new address is https://aviationweather.gov (note the lack of "www'). If you are using a link which contains "cprk" or "bldr", those links will no longer work. They have not been operationally supported since October 16th and the servers were fully decommissioned last week. Please update your links to use the new site. We have a URL migration guide available at https://aviationweather.gov/help/#url and a video tutorial for the new site at https://www.youtube.com/watch?v=Sdkx3UWeflI .

As part of the website upgrade, the static satellite images have been discontinued. This is because the new website is centered around an interactive and fully customized map, and the satellite imagery has been incorporated into that map. To view satellite imagery on the new site, click the "Weather" menu at the top of the screen, then click "Observations". After the map loads, click the layer icon in the upper right corner of the map. This is where you can turn on/off the satellite imagery and switch between different types such as visible, IR, and water vapor. Additional customization settings are available by clicking the gear icon to open the settings menu (press the blue “close” button to apply any changes).

Kind regards,
Lewis Kanofsky

And here is my comment for upstream developers 

https://github.com/rgleason/weatherfax_pi/issues/157#issuecomment-1941974341

An update of opencpn-weatherfax-plugin is inside updates_testing 
correcting this bug : https://bugs.mageia.org/show_bug.cgi?id=32782#c3

-------------------------------
Bugfix Advisory 
------------------------------

Since january the US National Oceanographic and Atmospheric Administration (NOAA)
doesn't provide anymore aviationweather faxes
This addresses need to be removed from the plugin

Some typos in ASCAT addresses preventing to get some faxes are corrected

RPMs for each arches
opencpn-weatherfax-plugin-1.9.110.1-4.git20231106.mga9
----------------------------------

To test this
Before the update
- opencpn-weatherfax-plugin proposes aviationweather faxes but you can't get them

- you can't get ASCAT faxes for San Fracisco and Charleston

after the update 
- opencpn-weatherfax-plugin doesn't propose aviationweather faxes

- you can get ASCAT faxes for San Fracisco and Charleston


NB inside the ASCAT faxes the wind arrows don't cover the whole square window
it's normal and due to the way the satellites function : they draw alternate strips around the globe
(I will attach two pictures to explain this)

one coverage by the satellites

The satellites need several passage to cover the whole planet
Each passage generates strips of images

the squares on this world map draw the limits of the faxes we can get at the date and time we download them

These squares may be partially fulfilled 
see next attachment

Created attachment 14408 [details]
ASCAT fax covering Greece

As you may see, the wind arrows cover only two strips on the fax
it's the normal behaviour

A fax got later will have only one strip fulfilled covering the sea in the south of Peloponnese

PS
This may be proposed to QA as soon as the rpms are uploaded to the repos (they are already built by the BS)

MGA9-64 Plasma Wayland on HP Pavillion
No installation issues overwriting previous version.
Beats me how to test this, I looked at previous update, but I see no icon in the iconbar, not do I have a clue how to "activate" this.
Video from Google does not help either  since this demonstrates the use in some unspecified geo-application.

Hi Herman

You need to activate this plugin :
In the menu bar choose "tools" ("Outils" in French)
When it's unfold choose "options"
then choose "plugins" ("Compléments" in French)
then activate the WeatherFax plugin by clicking its button
Then click the button "apply" and "OK" in the bottom of the plugins window

the icon of weatherfax will appear in the icons bar (I will attach this icon)

Click on the icon => a little window appears
in this window click on "retrieve" ("récupérer" in French)
choose "internet"
a new wider window appears 
in the list of providers :
there's no more AviationWeather

choose ASCAT B
in the list of ASCAT B regions choose San Francisco
in the upper part select one of the two (Metop B ascending or descending)
then click on "selected"

a new window appear with a stripe of wind arrows over the ocean in the region of San Francisco

@Philippe
I'm still missing something Tools Options occurs in a lot of programs, which one are you refering to???

You can't test this plugin outside of OpenCPN !

First step : launch OpenCPN...
 and then you can follow what I explain in https://bugs.mageia.org/show_bug.cgi?id=32782#c11

Looking further around, I realized opencpn is an application on its own. Follwing your guidelines, I got a window of part of the North Sea. Tried San Francisco as well.
So as far as I see, this works OK.
