Lunar Observing

[هانیه امیری]

Hello dear moonwatchers

In this topic, we will discuss about everything which relates to our Moon & its observing points such as watching it's surface features

We will learn here about the only world other than the Earth which man could land on it

so join & help us:have%20a%20nice%20d

Saturday, May 5, 2012: Tonight's full Moon will be the year's closest and largest one

Full Moon arrives at 11:35 p.m. EDT ,in Libra. Coincidentally, our satellite reaches perigee, the closest point in its orbit around Earth, at 11:34 p.m. EDT. It then lies 221,802 miles (356,955 kilometers) away from us. But the Moon will be only 8% closer and larger than average and will shine only 0.16 magnitude brighter than average

I hope the clouds will be clear for all and allow us to watch and photograph tonight's fantastic moon

Have a nice and clear night sky:have%20a%20nice%20d

Thank you Mr farshad for sharing your wonderful shot with us. I will use your shot to describe the famous craters of moon and some tips to observe them




Tonight's moon is the biggest and brightest since 2006 and until 2018 and unfortunately some cities lost this chance due to the bad condition of weather





Clear skies to all of you:have%20a%20nice%20d

Ok, let me start with Some Definitions for Moon features

How Are Lunar Formations Named?

Craters:


Large craters: Famous deceased scientists, scholars and artists;

Small craters: Common first names.


Catenae, Dorsa, Rimae:

Feature names derived from nearby craters.

Lacus, Maria, Paludes, Sinus:

Latin terms describing weather and other abstract concepts.

Montes:

Terrestrial (earthlike) mountain ranges or nearby craters.

Rupes:

Name of nearby mountain ranges (terrestrial names).

Vallis:

Names derived from nearby features.

Even though we’ve been studying the moon for decades, we still have a lot to learn. One of the best ways to learn more about the moon is studying its craters.



Studying craters may sound strange, but craters can tell us a lot about the moon’s surface: how old is it, how thick the soil (FYI: lunar soil is called regolith) is, what types of erosion processes took place on the moon, and what might be underneath the surface. Of course, studying craters will also give researchers a better idea of how hard and how often the moon has been hit with various objects




Let's continue with the first and the most famous crater of the moon.



Certainly the most obvious crater on the Moon is Tycho in the southern hemisphere - which named after the Danish astronomer Tycho Brahe (1546-1601

Tycho Crater, about 85 kilometers across, is clearly visible on our Moon's surface. The freshness of the crater and the rays of material radiating from it suggest that this is a young crater; there has been little erosion for it. Tycho Crater appears close to the south pole of the Moon. This circular crater is surrounded by a bright ejecta blanket. Rays of ejecta extend across the lunar surface

Omar Khayyam is a lunar (http://en.wikipedia.org/wiki/Moon) crater (http://en.wikipedia.org/wiki/Impact_crater) that is located just beyond the northwestern limb of the Moon (http://en.wikipedia.org/wiki/Moon), on the far side (http://en.wikipedia.org/wiki/Far_side_%28Moon%29) from the Earth (http://en.wikipedia.org/wiki/Earth). It lies in a region of the surface that is sometimes brought into view of the Earth due to libration (http://en.wikipedia.org/wiki/Libration), and under favorable lighting it can be viewed from the edge. However under such circumstances not much detail can be seen, and the crater is best viewed from orbit (http://en.wikipedia.org/wiki/Orbit).

This feature is located at the western edge of the larger walled plain Poczobutt (http://en.wikipedia.org/wiki/Poczobutt_%28crater%29), and the northwestern rim of Omar Khayyam is overlain by the crater Zsigmondy (http://en.wikipedia.org/wiki/Zsigmondy_%28crater%29). The east-southeastern part of the interior floor of Omar Khayyam is overlain by a smaller and younger crater. The remainder of the interior floor is split in half by a ridge attached to the western outer rim of this crater, giving Omar Khayyam the appearance of a formation composed of multiple merged impacts.

The outer rim of Omar Khayyam is heavily eroded, and has a wide gap to the southeast. A small crater overlies the western rim, and multiple small craterlets mark the sides and parts of the interior. The floor to the southwest is somewhat smoother than elsewhere.

this evenin' we've experienced an unsuccessful new moon observing:(
it was our initial observation in lunar observing...the horizon was hiding by thick clouds....and the surface of hole city was full of dust
the illumination of this new moon was about 1.5% and it's altitude was 4 degree

Thank you dear gandom for your comment & report :)

I hope better observations for you in the future & we will be glad to see your reports from them

Thank youuu ;)
