Hmm that’s actually something I hadn’t thought about, but yeah it probably wouldn’t work for an offline mode… If the app is already open, maybe it would work, but I’m not 100% sure. In general, it does require internet to connect to your home assistant (my phone is setup with wireguard to VPN into mind so it’s not internet facing). So yeah unless it can be used during those random connection drops, maybe not a perfect option :(
Huh, I’m pretty sure neowise had a lower magnitude. I was in a city at the time and could see it through the light pollution at night with the naked eye. This one disappears quickly in the dark after the sunset goes towards astronomical dusk… And the moon light is also making it impossible to see. Maybe looks brighter at sunset in specific parts of the world, but at least my experience in its glory was nothing like Neowise.
Also earthsky claims magnitude -5 to -7. I don’t believe that. For context, the magnitude of Venus is about -4 and that planet outshined the comet greatly.
