I was checking my feed to FR24, and noticed that the default map location for me showed 2 odd markers.
I take it these 2 markers (the round ones) are indicative of some kind of balloon? They are both at a very high altitude, so I assume they are some kind of project, or are for meteorological purposes.
Registrations were: N257TH and HAL02.
I looked on FA, and while I could find the registration, it seemed to have a differing track from FR24 (unfortunately, I did not consider to screencap that at the time), and none of the vector or altitude data. [edited to add this paragraph]
(It’s flattering that the FlightAware forums are the go-to place for ADS-B questions, but for technical support for FR24-specific questions you’re probably better off asking them)
Part of my rose-colored glasses attitude to asking on FR over FR24, is that it was obvious where the forums are here. Plus I’veexperienced the quality of responses one gets hereof.
Having delved a little deeper into FR24s site, now it’s somewhat obvious where to go for their forums too.
