Don’t be daft chips, it happens every single month. Trust me, I know the tides, and I have a front row seat.

isn’t it imaginable there might have been some anomaly in the air, maybe a warmer cloud or something like that, so Luna appeared larger to certain people while it wasn’t essentialy closer in fact?Very unlikely. Plus, it’s been widely said that the moon has in fact come closer than usual; that’s not something up in the air, it’s factual.

If you’re talking about the perigee and apogee - then they occur frequently, just the recent perigee they called a “super perigee” and has the moon at it’s closest to earth for the past 18 years, and coming 20 years
As said, he may have seen just that.However, I am accurate to say your location is not a factor (noticeable). The orbit means differences of up to 50,000km in the moon’s proximity. Perigee is still perigee whether you’re in US, UK, SA, Aus or Timbuktu!
So I’m confused about your post now

I’m simply saying Chips, that if you fish off the beach at high tides like I do, with only the sea as your horizon, then you actually notice these things. The moon is at it’s closest observable point to you when it rises over the horizon and as it rises it gets further away, so you can really see when it’s big and in your face, which happens on the biggest tides every single month.
As you know, the proximity of the moon to us determines the height of the tide, we get one big high tide of around 13 metres and then roughly 2 weeks later we get our smallest high tide of around 6 metres where I am, that should give you some idea of the difference in pull acting on the sea between the perigree and apogee as you put it. It shouldn’t take you more than a second or two to realise that’s a big difference in proximity to us, but I doubt you ever get a chance to regularly observe that difference.
If you live in land, you probably only see the moon when it’s already up off of sea level and probably don’t look at it much anyway, when you fish and have nothing but sea and darkness to look at, you look at the moon a lot. So super perigree or not, the moon looks bloody big when it’s at the closest point in it’s orbit.
Simply put, if you don’t observe the moon much, and one night you happen to be in the right place, at the right time, with a good view of the horizon, then you will think the moon is massive compared to what you usually see, super perigree or just your average one. Does that make sense to you?

That is actually false. This part is an optical illusion caused by the atmosphere.
The difference in distance you get in a day is negligible.

That maybe so, but you can still tell when it’s bloody bigger than usual. lol.

As FF says, illusion. The distance between the moon and yourself is greater when it is on the horizon than when overhead.
As for monthly tides, there are the spring tides every fortnight which generally have the greatest regular range and are larger than the perigee typically as far as I was aware?
Obviously tides are also affected by the perigee/apogee - but only every couple of months do the two coincide to give the greatest tidal range. At least that’s all I remember from it being explained when we were sailing!

Saturn is easier to observe (well, moon is easier than all), and now she in the good position for observe from earth, SO don’t waste your time to see the moon, because you can see it everyday.
I seen the saturn in the night time of day before yesterday, a orange tiny spot in the sky. But unfortunately, when i deployed my small telescope, clouds fall….
In the next few month, July, you can see the Jupiter and Saturn in one single night, wow that’s very exciting.
-
So this is beginning to look like I’m simply being decieved by a full moon (which obviously looks bigger than normal anyway) at high tide, and an optical illusion caused by the atmosphere. So about the only bit I’ve got right is that the stood in the right place at the right time the moon can look bloody huge.
I can live with that. -
Sorry have to come back to the last page:
I am sure that the distance between earth and moon is dependent on where on earth you are. Just an example (i know this wont happen in real but its better for understanding):If you live on the north pole and the moon crosses the northern sky then i am sure you are closer to the moon than you are from the south pole or equator
Generally it interesting how many start are there or planets that you could see and the less of us know them by heart

That’s also not true. The optical illusion is not caused by the atmosphere but rather by other circumstances that are still being debated.

Btw. this does not only apply to the moon, but any object in space you can see from earth. (like the sun!)

From what I understand (and I grant this is very limited!) The moons orbit is slightly eliptical, but not by very much. Apparently it varies over a period of around 14 lunar months, thus resulting in greater tides at certain times during the course of the year. In addition to this, there are other changes that occur, such as the moon being at full or the earth and sun being closer to the sun (due to variation of the earths orbit of the sun) that have an impact of how close the moon looks or how bright it is. I would say that the media often exaggerate these kind of things. I’m not sure on the credability of whether or not this is truly the closest the moon comes for another 20 year, seeing as it was supposedly closer than it came this time around only a few years ago.
Anyway back to mercury, I wouldn’t want to live on that planet, that’s for sure.

OKay… Here is Saturn … with bad weather…PS: Guys, i worked with it for a whole night, i need some encourage please
Thats awesome! Hopefully youll get a clearer night at somepoint so its not so blurry
good job!

Thank you cheese
I will still work with this, maybe next time for Mercury, when air is clear and i’m free.

Sorry, I hate to be ridiculously pedantic, but you mis-interpret. The distance from the moon to YOU may vary depending upon where YOU are. You are varying the position of a person on the earth, or talking about the distance from specific points of surface to surface. The specific points vary based upon their location given rotation.
However, I must point out the specifics of my post:
The distance from the centre of the moon to the centre of the Earth is not dependant upon where on the earth you are standing
As for your second point, not necessarily. Simple and most extreme counter example is during winter for the Northern Hemisphere (no daylight at north pole) and a New Moon (moon between sun and earth). To put more into this, the moon doesn’t orbit around the poles, but around the elliptic plane with some variation (admit, my interpretation isn’t necessarily 100% accurate).
Earth: http://en.wikipedia.org/wiki/File:AxialTiltObliquity.png
Lunar Orbit: http://en.wikipedia.org/wiki/File:Lunar_perturbation.jpgThe Moon differs from most satellites of other planets in that its orbit is close to the plane of the ecliptic, and not to the Earth’s equatorial plane. The lunar orbit plane is inclined to the ecliptic by about 5.1°, whereas the Moon’s spin axis is inclined by only 1.5°
http://en.wikipedia.org/wiki/Orbit_of_the_Moon
Earth axial tilt is 20 something degrees. So I think the moon is pretty much “closer” to the equator* than north pole, but I’ve not done any math based upon my rudimentary understanding to verify, so possibly talking out of my buttocks
As for photo of Saturn, awesome
What were you using equipment wise?*where equator does not refer to the whole equator of the earth, as obviously a point on the equator on the opposite side of the earth is further at a single point in time than the north pole. Talking about an individual point where the point along the equator is, at that point in time, the closest point along the equator to the moon, whereas the north pole remains…the north pole throughout.
