宇宙天気予報センターは、宇宙天気に関する観測、予報、警報を提供する米国の公式情報源です。このサイトでは、太陽風の速度と密度、惑星間磁場、X線束、陽子と電子の束、惑星のKp指数など、太陽と地球近傍宇宙の現在の状態が表示されます。
警報、注意報、警告は、 地磁気 嵐、太陽放射嵐、無線通信障害について、NOAAの1～5段階スケールを用いて、電力網、衛星、HF無線、GPSへの影響度を予測します。オーロラ予報マップ、太陽画像、3日間予報も含まれており、データは機械可読形式でも利用可能です。
非常に質の高いデータとグラフィック
このサービスは、衛星、電力システム、航空、測量、無線通信の事業者だけでなく、オーロラ観測を計画しているすべての方にとって有益です。無料で登録も不要です。データは数分から数時間間隔で更新されるため、各プロットのタイムスタンプを確認してください。

|---|---|---|---|
| Institutional role: SWPC is part of the NOAA National Weather Service. It issues forecasts such as the 3-Day Forecast and the 27-Day Outlook, plus alerts, watches and warnings. | Institutional role: It is an independent service that republishes and visualizes data from other organizations. Its reports draw on SIDC and NOAA SWPC, and its solar images come from SDO, STEREO, PROBA-2, SOHO, GOES and SOLAR-1. | Institutional role: The ESA Space Weather Service Network is a federated European structure with a coordination centre in Brussels, five expert service centres and a data centre in Redu, Belgium. | Institutional role: It is an independent, editor-led site run by Tony Phillips. Content mixes news, scientific data and photographs from professional and amateur astrophotographers. |
| Products and scales: Ratings follow the NOAA Space Weather Scales for radio blackouts (R), solar radiation storms (S) and geomagnetic storms (G). Community dashboards target aurora, aviation, electric power, emergency management, GPS, radio and satellites. | Products and scales: It provides flares, sunspot regions, CMEs, coronal holes, Kp index, auroral oval, magnetometers, webcams and aurora forecasts, plus an archive of solar and geomagnetic data back to 1996. | Products and scales: An ESA page lists services for spacecraft operations, human spaceflight, launches, communications and navigation, power grids, aviation, pipelines and auroral tourism, each with data products, toolkits and expert support. | Products and scales: Coverage includes aurora, solar activity, the magnetosphere, meteors and near-Earth asteroids. A searchable archive starts on 1 January 2001. |
| データアクセス: The data service at services.swpc.noaa.gov provides text, image, product and JSON endpoints. NCEI is the long-term archive, and an FTP warehouse is also available. | データアクセス: It offers a website, mobile apps for iOS and Android, push notifications, an RSS feed and social media channels. A programmatic data interface is not described on the page checked. | データアクセス: Access is through a dedicated portal run by the coordination centre. The page checked does not describe an API. | データアクセス: The sources checked describe a website and an archive and do not describe an API. |
| Cost, ads and terms: The data access page states no licence, usage terms or access restrictions and refers to the NOAA and National Weather Service disclaimer. | Cost, ads and terms: The website and app are free but show advertising, a Pro subscription removes ads, and donations and merchandise support the service. | Cost, ads and terms: The site carries advertising, for example for books, telescope retailers and observation tours. | |
| Status and caveats: It presents NOAA scales and alerts that describe expected impact on infrastructure. Products update at different intervals, so the timestamp of each plot should be checked. | Status and caveats: Alert types can be switched on or off in the app. | Status and caveats: The ESA page describes the network as pre-operational with live support only in working hours, so its current status should be verified on the ESA portal. | Status and caveats: It is not described as an official or government source, so it complements, and does not replace, an operational service. |
