Today the moon is 226,480 mi away and looks 32′ 46″ across.
Solunar periods
Today's activity: medium- 12:37–2:37 am Major · the moon passes overhead · high activity
- 1:09–3:09 pm Major · the moon passes underfoot · high activity
- 9:01–10:01 am Minor · moonset · medium activity
- 6:14–7:14 pm Minor · moonrise · medium activity
According to solunar theory, fish feed more when the moon passes overhead or underfoot (major periods, about 2 h) and when it rises or sets (minor periods, 1 h). It works best around new and full moon.
