SUMMARY

This discussion focuses on the reliability of satellite sight predictions for Starlink using various tracking websites. The user reports inconsistent results with Find Starlink, noting a significant discrepancy of 20 minutes between actual sightings and predicted times. Recommendations include using Heavens-Above for more accurate predictions, emphasizing the importance of setting location and time zone. The discussion highlights that if multiple sites like findstarlink.com, james.darpinian.com, and heavens-above.com align on predictions, they are likely accurate, but brightness predictions can vary significantly.

PREREQUISITES
  • Understanding of Low Earth Orbit (LEO) satellite visibility
  • Familiarity with satellite tracking websites like Heavens-Above
  • Knowledge of astronomical magnitude and its impact on visibility
  • Basic skills in setting location and time zone for accurate predictions
NEXT STEPS
  • Explore the features of Heavens-Above for satellite tracking
  • Research the effects of orbital changes on satellite visibility
  • Learn about astronomical magnitude and its implications for satellite brightness
  • Investigate additional satellite tracking tools and their accuracy
USEFUL FOR

Astronomy enthusiasts, satellite trackers, and anyone interested in optimizing their chances of spotting Starlink satellites.

Hi.

I haven't been lucky once with the times on Find Starlink, despite trying about 10 times. However, last week I once saw a group by pure accident, and when I compared with that website it was about 20 min after the last predicted time.

Are there websites with more reliable predictions?

They actively change their orbit, that makes tracking difficult.

If findstarlink.com, james.darpinian.com and heavens-above.com all agree on the predictions they are probably not too wrong, otherwise you can get at least a rough time range. The brightness predictions can be even worse than the time predictions, however. A prediction of magnitude 2.5 (easily visible from most places) can turn out to be 4.5 (really difficult to see from many places) or something like that.
