- Appearing as such but not necessarily so; seeming: an apparent advantage. ...
- Synonyms: apparent, clear, clear-cut, distinct, evident, manifest, obvious, patent, plain.
- These adjectives mean readily seen, perceived, or understood: angry for no apparent reason; a clear danger; clear-cut evidence of tampering; distinct fingerprints; evident hostility; manifest pleasure; obvious errors; patent advantages; making my meaning plain. Usage Note: Used before a noun, apparent means "seeming": For all his apparent wealth, Pat had no money to pay the rent.

- Apparent Rest .
- Metelli (1940) was so impressed with this lack of potential motion that he called this phenomenon "apparent rest". Apparent rest may be understood as a demonstration of the role of occlusion on motion integration. ... For an alternative interpretation of apparent rest in terms of a homogeneity principle, see Metelli (1965).
4. Apparent Superluminal Velocity of Galaxies
- math.ucr.edu
- Apparent Superluminal Velocity of Galaxies.
- Indeed, we can calculate that if its real velocity is v, then its apparent velocity in this case is v/ sqrt(2)-(v/c) which could be higher than twice the speed of light without v being greater than c. For galaxies moving at more acute angles to the line of sight the apparent velocity can be much higher. Similarly, if the object is moving away from us, the apparent angular velocity will be too slow, if you do not correct for this effect, which becomes significant when the object is moving along a line close to our line of sight.

- In actuality, it is a trick of the orientation of the jet and the angle it forms with the Earth which produces the apparent super-luminal speed. ...
- 326 yr, the time of apparent emission from the base of the triangle as viewed by a distant observer. ... 754 yr, which is the apparent time it took the jet to move from one side of the triangle's base to the other, a distance of. ... Thus, the apparent velocity is. ...
- 191 yr, the time of apparent emission from the base of the triangle as viewed by a distant observer. ... 789 yr, which is the apparent time it took the jet to move from one side of the triangle's base to the other, a distance of. ... Thus, the apparent velocity is. ...
- There are obviously many combinations of angle and apparent velocity with respect to the observer which require a velocity of the jet with respect to its source equal to or greater than c. One additional example is a jet of gas streaming from the center of M87, with an apparent velocity of 2. ...
- 754 yr, and the apparent velocity along the base is again. ... Thus, in RCM, the velocity required of the gas jet with respect to its source to produce an apparent velocity of 1. ...

- Near the horizon, refraction will raise an object on the horizon (like a star or the Sun) to an apparent position about 0. ... More variable local atmospheric effects, like the Novaya Zemyla Effect, can increase the effect of the refraction by an order of magnitude or more! This refraction effectively hastens the apparent rising of the Sun and delays the apparent setting of the Sun. ...
- Near the horizon at B (where sunlight strikes the atmosphere at a low angle and must travel through significantly more air to reach Earth's surface), atmospheric refraction can raise the actual position of an object on the horizon to an apparent position 0. ...
- 5°, so atmospheric refraction raises the actual Sun that is just below the horizon to an apparent position that is just above the horizon. ...
- The diagram to the left shows the apparent Sun (in yellow) just beginning to set, while the actual Sun (in white) has just set.
- Since the Sun's rate of motion across the sky is 1° every 4 minutes (15°/hour), the apparent Sun will set 2 minutes later than the actual Sun.
- Similarly, the apparent sunrise occurs 2 minutes earlier than actual sunrise. ...
- On the diagram to the right, drawn for NY at latitude 41° N, the apparent Sun is just beginning to set as the actual Sun (directly below it) is just finishing setting. Notice that the apparent Sun must move farther than 0. ...
- An interesting additional effect of atmospheric refraction is the fact that the apparent sunrise and sunset azimuths are shifted north (in the northern hemisphere) of due East by (0. ...

- You might think that the meaning of a word like apparent would be, well, apparent. ... Used before a noun, apparent means seeming: For all his apparent wealth, Pat always had trouble paying the rent. Used after a form of the verb be, however, apparent can mean either seeming (as in His virtues are only apparent) or obvious (as in The effects of the drought are apparent to anyone who sees the parched fields), so be careful that the meaning you want is clear from the context.
10. RR Lyrae Stars and the Distance to M4
- www.astro.washington.edu
- If we can determine a mean apparent magnitude (m) for an individual star in a globular cluster, we can calculate the distance to the star and thus the globular cluster by using the magnitude equation: .
- At 7000 light years distance (2150 pc), M4 is the nearest globular cluster, as seen from its large apparent size. ...
- Using the calibration of standard stars, we find a "diameter-versus-apparent-magnitude" correlation by assuming the two are linearly related. ... Once we have this relationship, we simply measure the diameter of Star #42 in each of the 20 frames and determine the corresponding apparent magnitude from the graph. Since the change in the star takes place as time passes, we then graph apparent magnitude versus time to see the change in its brightness. ...
- What you will turn in: 1) your table of apparent magnitude versus diameter for the standard stars; 2) the graph of apparent magnitude versus measured diameter; 3) your completed table on the apparent magnitude versus time for Star #42, 4) the graph of apparent magnitude of star #42 versus time; and 5) the answers to the "calculations" and "questions" sections. ...
- Click on the image ON-LINE and you will get an enlarged interactive version set up in a program that allows you to measure the width of the standard stars (indicated by their apparent magnitudes being written next to them) in pixels. ...
- Once you have calculated the diamters of the standard stars, plot apparent magnitude versus diameter (in pixels) on the graph (Apparent Magnitude vs Measured Diameter in Pixels). You will then have a graph of the apparent magnitude of each standard star (y axis) as a function of its measured diameter in pixels (x axis). ...
- Using your calibration-of-apparent-magnitude-versus-diameter graph from the standard stars, interpolate the apparent magnitude for the variable star for each frame and record in column 6. Plot apparent magnitude vs. time (where the time is given in the fraction of the day since the observations started) on a apparent magnitude of star 42 versus time graph. ...
