Leather Scale Armor

For the purpose of our Larp events I started making my own costume for the character I usually play. For the armor I decided to create a lightweight Scale armor made of leather. First I had to find out what shape of scales would give me the desired look. Scales can be found in a variety of shapes from simple squares to more complex patterns.

Scales and rivets.

After cutting out all the scale pieces (a lot of them) add poking holes through the corners, it was time to bind them together. This can be done in many ways, for example binding them with rope, metal rings, rivets… The look I was going for involves rivets (around 200 rivets used for the whole armor). Every scale, except those on the edges of the armor, is connected to four neighboring scales.

Breast-plate (front view).

For fastening the armor around the torso, there are two leather straps located just under the armpit. They can be easily adjusted by the wearer at any time.

Back-plate (back view).

Armor is not finished yet and it is still in the process of making. The next step is to add pauldrons to cover the shoulder area and upper arms.

Geminids 2014

Every year from 12. to 15. there is an increase in number of observable meteors as the Earth passes through the debris left by an asteroid known as 3200 Phaethon. Geminids are therefore somewhat unusual as meteor showers go. While most meteor showers are born from comets, the Geminids appear to be a leftover of an asteroid. In good conditions, away from street lights, up to 130 meteors can be seen per hour.

This year’s bad weather conditions continues throughout the month of December. I was able to observer the shower only one night. Bellow is the only brighter meteor that I was able to capture during the observation.

Sky this month – December 2014

Here is a list of astronomical events for given month. Location dependent events listed here are visible from central Europe.

DECEMBER 2014:

1 – The Phoenicids (PHO) meteor shower peak, with variable ZHR. The peak time is forecasted to be between 23:00 UT and 1:00 UT on December 2.

6 – Full Moon at 12:27 UT.

9 – A double shadow transit of Jupiter’s moons occurs from 4:18 to 4:27 UT. At that time Jupiter is very high in the sky in Europe.

14 – The Geminid (GEM) meteor shower peak, with ZHR around 120, peak at 1:00 UT.

20 – The December Leonis Minorids (DLM) meteor shower peak, with ZHR around 5.

22 – New Moon at 01:36 UT.

13 – The Ursuids (URS) meteor shower peak, with ZHR around 10 (can be variable up to 50), peak at 20:00 UT.

Sky this month – November 2014

Here is a list of astronomical events for given month. Location dependent events listed here are visible from central Europe.

NOVEMBER 2014:

1 – Mercury reaches its greatest elongation 18.7° west of the Sun, shining at magnitude -0.5. The best morning apparition of Mercury of 2014 for the northern hemisphere observers.

2 – Asteroid (1118) Hanskya occults a +8.5 magnitude star at 19:43 UT for 9 s and magnitude drops for 6.7, detailed info.

5 – The Moon occults bright star ο Psc (mag. +4.3) at ~17:00 UT. For the exact times see the detailed timetable.

6 – Full Moon.

10 – The Southern Taurids (STA) meteor shower peak, with ZHR around 5. Very slow and often bright meteors.

12 – The Northern Taurid (NTA) meteor shower peak, with ZHR around 5. Very slow and often bright meteors.

17 – The Leonids (LEO) meteor shower peak at around 22:00 UT, with ZHR around 15.

18 – Saturn at superior solar conjunction. Not observable as the planet is placed behind the Sun.

22 – New Moon.

Solar prominence 31 October 2014

Short animation of the ever changing solar prominence. It consists of 38 frames at frame-rate of 15 fps. Still frames were acquired from 11:10 to 11:50 UT. Every still frame is registered and processed imaged, made out of 45 seconds long video. Seeing conditions were very poor.
