Summary[edit]
| Description |
Ελληνικά: Έκλαμψη τηλεπικοινωνιακού δορυφόρου iridium (iridium flare). Οι δορυφόροι έχουν ηλιακά πάνελ για τη τροφοδοσία τους με ηλιακή ενέργεια. Αυτά, καθώς οι δορυφόροι περιστρέφονται γύρω από τη Γη, ανακλούν το φως του Ήλιου και προς την επιφάνεια της Γης. Σε κάποια δεδομένη χρονική στιγμή, ο δορυφόρος θα διέλθει πάνω από κάποιον γήινο παρατηρητή με τέτοιο τρόπο, ώστε τα ηλιακά πάνελ να ανακλούν το ηλιακό φως κατευθείαν στο σημείο που βρίσκεται ο παρατηρητής. Τότε αυτός μπορεί να δει αυτή την έκλαμψη σαν ένα προσωρινό έντονο φως που μπορεί, τη νύχτα να φτάσει σε φαινόμενο μέγεθος ακόμη και το -8 (σαν ένα πολύ αργό αλλά πολύ φωτεινό «πεφταστέρι»). English: iridium flare above Athens. When an iridium satellite passes above an observer and its solar panels are in the proper angle against the Sun, so to reflect sunlight directly to the observer. Then, the observer sees this flare which can reach an apparent magnitude of up to -8 or even more sometimes (like a very slow but very bright meteor). |
