據中國之聲《新聞縱橫》報道，在剛剛過去的中秋之夜，一顆“火流星”滑亮了雲南省迪慶州的夜空。根據相關天文機構公佈的資訊，隕石墜落的地點，可能位於香格里拉市的巴拉格宗景區範圍內。

事發一週之後，昨天（11日）下午，記者專訪了巴拉格宗景區相關人員。對方稱，目前還是沒有確定隕石墜落的具體位置。最近，有很多人員都在當地尋找隕石，但至今沒有任何訊息。雖然隕石還沒有找到，但在網上有關隕石歸屬的問題已經引發了討論。

巴拉格宗景區的工作人員洛桑培楚說，事發當時，景區的多位工作人員都目睹了那顆“火流星”，“因為我們酒店的位置，剛好是在一個U字型的峽谷裡，感覺突然間天空特別亮，有個東西就飛過來了，打在對面的崖壁上，過了幾分鐘之後，就聽見咚的一聲，附近村民有明顯的震感。”
