On August 12 an IP from EUMETSAT changed some of the capitalization followed immediately by same person Does this make it authoritive It certainly seems that EUMETSAT have their own convension but many others uses the capitalization as originally provided in this article such as this one from the UK s Met Office and from Space Flight Now and from RMETS ORG and this one of the owners and of course the ESA links However this article from the Guardian and this from the BBC follow EUMETSAT s convension Also the Met Office can t make up their minds as with this article EUMETSAT might be the operators but are they the authority in the naming convention used Anyway if there are no objections after a suitable period to give time for other editors to review this I see no reason not to make the change Chat
