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 (°)
2006 Mar 22 16:53 -28.725 Sep 15 01:28 28.725
2025 Mar 22 06:47 -28.719 Mar 7 15:56 28.710
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
2080 Sep 21 02:33 -28.695 Oct 5 09:52 28.682
2099 Sep 21 11:16 -28.686 Mar 29 02:46 28.678

20 Jan 2025 Cookham Dean Primary school - (outreach)
Monday, 20 January 2025, Cookham Dean Primary school (outreach).
MAS team: Robin O, Steve B (report), Andy T (report)
Steve B
This was one of our regular visists to the school to deliver talks to the Year 5 students on astronomy as part of their STEM activities.
I was the last to arrive, so parked in the street outside whilst Robin and Andy managed to find a space in the staff car park. It was a cold overcast day with no possibility of observing the sun, so I unloaded my kit to set up in the school hall which was being cleared after lunch. Robin soon joined me, whilst Andy set up in one of the classrooms.
The year was split into two halves, each of around 10 or 12. The first half soon arrived in the hall where we split them into two teams of around 5 or 6 each. The first activity was to lay out the Solar System using the split scales, one for Planets, the other for orbital Distances. Both teams completed the task with good accuracy. This was followed by a short question and answer session.
Whilst I arranged the solar system kit for the next half, Robin delivered a talk on telescopes. Having explained how they work and showing his telescope, I demonstrated my Dobsonian and we concluded with another Q and A session. The students were very keen, posing many questions. Indeed the Q&A had to cut short when we noticed the second half of the year were queuing outside !
We then went through the same activities again for the second half. Although there were fewer questions, I soon noticed that we had over-run by 15 minutes. Realising that parents would be waiting outside, we brought the talks to an end.
Andy T
Inside the classroom Andy used Stellarium to show the young astronomers what was visible in the night sky. With four of the five naked eye planets above the horizon in early evening this was a good time for them to start observing. After locating Venus, Saturn, Jupiter and Mars pupils were shown how to use the Plough to locate Polaris in the north and how that enabled them to discover the direction of south, east, and west.
Showing the class an inflatable Earth they were asked to estimate the size of our Moon on the same scale. A good number were able to get close to the correct answer, and Andy showed them a juggling ball of the right dimensions. They were then asked estimate how far the Moon should be from Earth. As often happens the distance was greatly underestimated. Explaining that the Moon was ten times the circumference of Earth away was followed by slowly unreeling a string of the correct length resulted in the Moon being in the corridor outside their classroom while earth was in the far corner several metres away.
Both these demonstrations were punctuated by many interesting questions that prompted good debates amongst the class.
