Kohouteks Comet will become visible to the unaided eye some time in November, when it will appear as a morning star. Scientists say its brightness will increase until when to it rounds the sun reappear in the evening sky. The comet is expected to disappear from view mid-Decemb- in er mid-Februa- ry. Astronomers estimate the mass cf the comet to be nearly one trillion tons, equal to four times the weight of Mt. Olympus, located on the east side of the Salt Lake valley. Brightness is difficult to predict, since it depends on the way the comet is affected by solar winds. A comet is much like a large, dirty snowball. As it nears the sun, a wind generated by energy from the solar surface blasts the ice and creates a tail which reflects the light, he explains. Little is known about the origin of comets. Some, like the well known Halleys Comet, reappear periodically as they go around the sun in an elongated ellipse, while others swing in the solar system once and never return. Since each trip past the sun erodes the size of a comet, scientists conclude that those now in orbit must have been formed after the solar system came into being. Kohouteks Comet is the sixth new one sighted this year. Although astronomers have never observed the mechanism which permits the solar system to capture new comets into orbit, approximately three would have to be captured each century in order to sustain the present number. Kohouteks Comet will be the most intensively studied to date, and the first to be observed from space. Observations around the globe are expected to study the celestial object.

The crusade, sponsored by Beltone, is designed to build public awareness of the vital need for hearing conservation programs. Smith said the child suffering from an undetected hearing loss can also manifest such other symptoms as obviously straining to hear, confusing words which sound similar and becoming introverted or withdrawn for no apparent reason. Unfortunately, hard of hearing children often do not recognize the problem and teachers as well as parents can mistake inattentiveness or preoccupation for slow learning. A child with a hearing difficulty can encounter extreme problems in trying to learn something he simply cannot hear well enough to understand. At times he might be thought of as disobedient when in actuality he simply cannot clearly understand what is required of him. competitor with more desirable will be treated. game species.

D D D Have you inspected your electric motors lately? D 0 fl 0 n D D D D n D Electric motors are so dependable that it's easy to forget that they need attention occasionally, just like all mechanical equipment. Simple maintenance can prevent trouble or, worse yet, ,,burn-outM. Why do electric motors burn out? Generally for three reasons: (1) inadequate protection from overloading or single phasing or; (2) the motor has the wrong voltage rating; or (3) it is installed in a more difficult environment (ambient temperature, dirt, moisture, etc.) than that for which it was designed. The symptoms are fairly easy to spot. First, overheating. Second, the motors starter keeps tripping. Third, the motor wont start properly. To help avoid trouble with your electric motors and to prolong their lives, follow these guidelines: D Keep the motor clean, dry, ventilated and lubricated (use only approved D motor lubricants). If the motor is exposed to the sun, provide shade for it to eliminate excess heat. o Protect each of the incoming phase o lines with overload relays. Equip your motor starter with properly D calibrated overload relays to prevent damage in the event of a surprise overload. a motors on Utah Use Standard 230-vo- lt Power & Light Company Standard 240-vo- lt service.
