Have you ever seen the moon drop?

Have you ever looked up the night sky within a half-an-hour time frame and found that the moon has “dropped”? The first photo was taken on 5 Aug 11.10pm while the second photo was taken at  11.51pm.

But of course, this was just the moon’s oscillation around earth, and if you can catch the timing, you will be able to see the moon setting from the horizon in the western sky. In fact, moonset is the correct term  to be used. From the National Environment Agency website (http://app2.nea.gov.sg/moonrise.aspx), I saw that the moonset timing on 5 Aug was past midnight (i.e. early morning of 6 Aug). Hence, I picked another day when I can be around to spot the moonset.

On 3 Sep, I saw the same moonset. The pictures were taken at 10.27pm, 10.56pm and 11.19pm (when the clouds were not shrouding the moon crescent).

For those who have got sick of watching sunset, why not try watching the moonset the next time?
