Lulin Observatory

Lulin Observatory is a astronomy topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Lulin Observatory rather than just read about it. In short: The Lulin Observatory (Chinese: 鹿林天文台; pinyin: Lùlín Tiānwéntái, obs. code: D35) is an astronomical observatory operated by the Institute of Astronomy, National Central University in Taiwan. It is located at the summit of Mount Lulin in Xinyi Township, Nantou County.

Key takeaways

Lulin Observatory belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Lulin Observatory to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Lulin Observatory from memory before moving on to harder problems.

Reference excerpt

The Lulin Observatory (Chinese: 鹿林天文台; pinyin: Lùlín Tiānwéntái, obs. code: D35) is an astronomical observatory operated by the Institute of Astronomy, National Central University in Taiwan. It is located at the summit of Mount Lulin in Xinyi Township, Nantou County. In 2007, Comet Lulin (C/2007 N3), was found by this observatory, and became the first comet discovered by a Taiwanese researcher. The minor planet 147918 Chiayi was also discovered here. The Lulin 1 meter had its first light in September 2002, after 10 years of development.

Telescopes LOT Cassegrain telescope (D=1-m, f/8) SLT R-C telescope (D=0.40-m, f/8.8) by RC Optical Systems or 76-cm Super Light Telescope (SLT) Four TAOS robotic telescopes (D=0.50-m, f/1.9)

Lulin Sky Survey (LUSS) The Lulin Sky Survey searched for near-Earth objects from 2006 to 2009. The Lulin Sky Survey Telescope, a 16-inch (41 cm) Ritchey–Chrétien telescope with a field of view of 27 arcminutes, was operated remotely from mainland China, with robotic software developed in-house. In addition to searching for new objects, the survey refined the orbits of known minor planets and comets, and performed photometric analysis of a subset of objects. The principal investigator, student Quan-Zhi Ye of Sun Yat-sen University, was awarded the 2007 Shoemaker NEO Grant to develop the project. Ye later identified a comet from images collected in July 2007 by collaborator Chi Sheng Lin; the unusual retrograde comet, formally named C/2007 N3, became known as Comet Lulin. It made its closest approach to Earth in February 2009. Over the course of the survey, 781 new objects were discovered, including Comet Lulin and three fragments of comet 73P/Schwassmann-Wachmann. The LUSS project benefited from its location at a longitude with few other observatories looking for minor planets.

Worked examples

Example 1 — a first encounter with Lulin Observatory

Start with the simplest possible case. Write down what Lulin Observatory claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Lulin Observatory before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Lulin Observatory ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Lulin Observatory

In research: Lulin Observatory appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Lulin Observatory in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Lulin Observatory is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1999 establishments in Taiwan, Astronomical observatories in Taiwan, Buildings and structures in Chiayi County, so understanding it makes those chapters shorter.
In everyday life: Look for Lulin Observatory outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Lulin Observatory in simple terms?

Why does Lulin Observatory matter?

Because it connects several astronomy ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Lulin Observatory?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
