The Moon That Never Sets

It turns out that those of us living in mid to low latitudes have only been seeing half of the moon's trajectory!
Living in mid to low latitudes, we are used to the moon rising in the east and setting in the west. If we observe closely, we will notice that the moon's path shifts north and south every month, while the sun only shifts north and south once a year. From February 22 to March 7, I traveled to the Arctic Circle in northern Norway (around 69֯ N ). In the first few days, I found that I couldn't see the moon at all, day or night. It then dawned on me that the moon's path was too far south during those days, and because of the high latitude here, the moon was not visible.
However, in the latter half of the trip, on March 4 and 5, I discovered that the waxing crescent moon stayed in the sky all day and night! If the weather was clear enough, we could observe this waxing crescent moon remaining at the horizon for 5 to 6 days, much like the phenomenon of the midnight sun in the Arctic Circle, where the sun stays on the horizon continuously.
Unfortunately, due to the weather and my travel schedule, I couldn’t capture the entire trajectory of the moon across the sky. But during the early hours of March 5, while photographing the aurora, I managed to capture two segments of the moon's path. The left image shows the time from 00:30 to 01:52 on March 5, and the right image is from 02:48 to 04:07. In the left image, the moon is still descending, while in the right image, the moon appears to be moving horizontally just above the horizon. From the position of the North Star above, we can see that the moon has reached its lowest point and is beginning to "rise" again, though the movement is so subtle it’s almost imperceptible.
Additionally, the moon that appeared in the northern low sky at this late hour was a waxing crescent moon, which shouldn't have been visible at this time and direction! This phenomenon, where the moon never sets, is actually the other half of the moon's trajectory below the horizon. This is a sight we living in mid to low latitudes have never imagined, and it’s truly fascinating!
