Key stages follow a predictable timeline. The penumbral phase begins at 3:44 a.m. ET / 12:44 a.m. PT on March 3, when the moon first starts to dim. The partial eclipse begins at 4:50 a.m. ET / 1:50 a.m. PT, as the darker shadow becomes clearly visible. Then, totality arrives at 6:04 a.m. ET / 3:04 a.m. PT and lasts until 7:03 a.m. ET / 4:03 a.m. PT. Afterward, the moon gradually brightens as it exits the shadow. The whole show concludes at 9:23 a.m. ET / 6:23 a.m. PT.，详情可参考im钱包官方下载
