Observation
The star is easily found because of its brightness and apparent proximity to the star Capella. It is the apex of the isosceles triangle forming the 'nose' of the constellation Auriga. The star is bright enough to be seen from most urban locations with moderate amounts of light pollution. Visual variable star observers make an estimate of its brightness by comparing its brightness with nearby stars with a known brightness value.

Famous quotes containing the word observation:
“It is a great pity—but ‘tis certain from every day’s observation of man, that he may be set on fire like a candle, at either end—provided there is a sufficient wick standing out.”
—Laurence Sterne (1713–1768)
“Let observation with extensive view;
Survey mankind, from China to Peru;”
—Samuel Johnson (1709–1784)
“I should say that the most prominent scientific men of our country, and perhaps of this age, are either serving the arts and not pure science, or are performing faithful but quite subordinate labors in particular departments. They make no steady and systematic approaches to the central fact.... There is wanting constant and accurate observation with enough of theory to direct and discipline it. But, above all, there is wanting genius.”
—Henry David Thoreau (1817–1862)
