geophys.ac.cn is the website of the Beijing National Observatory of Space Environment, a legitimate research station under the Chinese Academy of Sciences. The domain has been registered for over ten years, and the site clearly identifies its parent organization with a real contact email. That transparency is reassuring – this isn't a fly-by-night operation.
However, the site lacks HTTPS encryption entirely. For a government scientific site, that's unusual and means any data you send or view is not protected. While you probably won't be making purchases here, if the site ever asks for credentials or personal information, proceed with caution. Most research institutions in China have modernized their security, so this gap is worth noting.
There's no privacy policy or social media presence, but those are typical for an academic resource site. If you need raw space environment data, geophys.ac.cn appears to be the real deal. Just don't treat it like a secure modern website – keep general safety habits in mind.
