| As the obscuration of the Sun increases the sky darkens, although it never gets as black as dead of night. |
|
| The obscuration of a celestial object which cannot be observed because another object is located between itself and the observer. |
|
| This results very easily in strong obscuration and influence on the antenna by these other objects. |
|
| It is however possible to reduce considerably the effects of extinction by combining 2 photometric bands in order to correct for obscuration. |
|
| They are also susceptible to local obscuration on the upslope side under moist flows from practically any direction. |
|
| The maximum obscuration of the sun takes place exactly at sunrise, so the best place to be to see it is the Yorkshire Coast with the horizon provided by the North Sea. |
|
| Supporting the Infantry in the assault entails close in fire, obscuration, precision strikes and the ability to effectively seal off or channelize an advancing enemy. |
|
| At the time of initial licensing, every licensee has the option of receiving a paper copy of the alcoholometric tables, laboratory table, obscuration tables or a compact disc containing all the tables, free of charge. |
|
| The angle?3 for categories H7, H8, H11, H14 and angle? for H13 defines the distance to the reference plane to which the obscuration shall at least extend. |
|
| The above-cited text is particularly interesting because it clearly describes an obscuration of the Sun, which, though causing dusk conditions, was not quite total where it was seen. |
|
| The faint galaxy, which lies in the direction of the constellation Sagittarius, had remained undetected because of obscuration caused by stars and dust lying in the disk of the Milky Way. |
|
| Occultation, complete obscuration of the light of an astronomical body, most commonly a star, by another astronomical body, such as a planet or a satellite. |
|
| The obscuration of the Sun due to its passage behind the Moon. |
|
| There was complete opacification of the left maxillary sinus with obscuration of the osteomeatal complex. |
|
| Light reflection complicated by the spectral reflection from the snowflakes and obscuration of landmarks by falling snow can reduce visibility and depth perception to nil in such conditions. |
