30 - 31 May Lunar Observations

I woke up much later than usual on the morning of May 30. The sky was already of a blue hue and hardly any stars were visible. I was only able to squeeze in a few shots before having to prepare for work.





 The sky was clear on the morning of May 31. I had to setup outside since the Moon was low enough for it to be obstructed by the neighboring houses. I was able to capture a several good close ups of the lunar surface.

May 26, 2013 Lunar Observation








Last night's Moon, a day after the full flower Moon. I used eyepiece projection to get a magnified image of the lunar craters. The Moon this month is in its perigee position, making it closer than it is before.

How Big is the Super Moon?

When looking at the super moon high up in the sky, most people don't really appreciate the increase in size. The reason, most probably, is that they have no way of actually comparing the size or relative scale. Most people expect a really dramatic increase in size.

I decided to stitch two lunar photos of mine which has been acquired using the same imaging setup [Skywatcher Explorer 150PL with Nikon D3100 at prime focus]. Here you can see the actual difference in size of the moon at perigee position and during normal days.



Here is a comparison done by Raven Yu of last month's Paschal Full Moon and the Super Moon.

Hopefully during the apogee position (November) we can make a more distinct comparison. :)

My super moon image, as well with that of a fellow pastor's kid from the Philippines, got featured in news-press.com

Update
Both images from the Philippines have been used by Michael Braun in his online news article for the Marco Island Sun Times:

Super Moon this Sunday

May 5-6, 2012 will not just be a full moon, but a Super Moon.
As the moon revolves around the Earth it an elliptical path it sometimes moves further away and sometimes moves closer. When it is at its furthest from us it is known to be at Apogee. When it is closest (about 50,000 km) then it is in Perigee. That closest approach makes it known as a super moon since it will appear much bigger and much brighter.

LUNAR HOCUM

Recently, my mom is bothering me about some news of a so called "super moon" thingy majig that her Facebook friends have been talking about. They say it's going to cause disasters and all sort of stuff and now with the occurrence of the tsunami in Japan I'm sure they're gonna spill out more assumptions, which to say, no offense, is nonsense!

So here I am to correct this hocum with scientific facts about the moon.

The moon as it orbits around the Earth will eventually come closer and also farther because of its elliptical orbit. The closest position of the moon to the Earth is called a Lunar Perigee. The Farthest position of the moon from the Earth is called a Lunar Apogee. While it is true that the gravitational pull between the moon and the Earth causes a tidal bulge, the Perigee position will not cause it to create the devastating scenarios that are spread through rumors.

Now what about the Tsunami in Japan, well the moon is not even over Japan at the time of the tsunami nor was it in its Perigee position. It is pure coincidence. The Earthquake doesn't relate with the moon's so called relative closeness to the Earth.

From POPSCI it says:
Past supermoons have coincided with natural disasters--the Indonesian earthquake in 2005, Australian flooding in 1954--but scientists note that those are unrelated, more likely than not. Says John Bellini, a geophysicist at the U.S. Geological Survey: "A lot of studies have been done on this kind of thing by USGS scientists and others. They haven't found anything significant at all." The tides will pull a bit higher, but earthquakes are almost completely unaffected and volcanoes are not likely to show unusual behavior. John Vidale, a seismologist at the University of Washington in Seattle, said "Practically speaking, you'll never see any effect of lunar perigee. It's somewhere between 'It has no effect' and 'It's so small you don't see any effect.'"

In reality, the Lunar orbit is expanding outwards. The moon as it revolves around the Earth slowly moves away into space. This means that when the moon approaches it's Perigee it is still further out into space compared to when it was before. Proof of which is the occurrence of annular solar eclipses which means that the moon is further out and their angular diameter is not big enough to cover the sun completely.
So, scientifically speaking, there is no way that the moon caused the tsunami.

Not understanding something and spreading false facts about it can cause confusion. The Mars hoax for example where they say that Mars will appear as large as the moon in the night sky is theoretically impossible. We have to be careful about the things we share.
