7 Mar 2025 (and 22) Major Lunar Standstill
March 7 & 22, 2025
A 'Major Lunar Standstill' is when the range of the declination of the Moon reaches a maximum (of almost 60 degrees). As a result, at high latitudes, the Moon's greatest altitude (at culmination, when it crosses the meridian) changes in just two weeks from high in the sky to low over the horizon.
They occur every 18.6 years as a consequence of the (18.6 year) period in the precession of the Moon's orbital nodes. Note also that the greatest extremes always occur near the equinoxes.
The last was in 2006, the next in 2025, here's a few more dates (Dec = declanation, as in RA/Dec) :-
Greenwich Mean Time (GMT)
Year Minimum Dec (°) Maximum Dec (°)

2043 Sep 12 11:52 -28.703 Sep 25 14:42 28.712
2062 Mar 31 23:35 -28.700 Mar 18 10:23 28.705

Maidenhead Astronomical Society may use Laser Pens as a pointer during outreach events and talks. Any such use will comply with our Laser Pen Policy, which may be downloaded from here (.pdf)

Children under the age of 18 and non-approved adults are not be allowed to use the laser pen at any time. Any member of the public bringing their own device (without pre-approval) is asked not to use it during one of our events (and will be asked to leave if they are not willing to comply with this request).
