Honolulu Star-Bulletin Thursday, July 17, 1980 Those Strange Glows on the Moon -By John Noble Wiltord, N.Y. Times. YORK-On the day before the first lunar landing July 1969, Apollo 11 structions Mission Control, a investigating astronauts front orbiting the moon and, on inthe crater Aristarchus. They were seeking the source of a phenomenon that had puzzled astronomers for years, a strange glow that occasionally flared out of Aristarchus. looking north up towards Aristarchus now.

Neil A. Armstrong, the commander, radioed. "There's a an area there that is considerably more illuminated than the surrounding area. It just has -seems to have a slight amount of fluorescence to it." At the same time, two amateur astronomers in West Germany reported in the independently, seeing, crater. Neither they nor the astronauts -nor, for that matter, professional astronomers- -could explain what they were seeing.

It was just one more of those fascinating episodes, known as transient lunar phenomena, suggesting that moon, though without air or life, is apparently not completely dead. Recent analysis of Apollo data and groundbased observations indicates that these glows, hazes, mists, brief color changes and temporary obscurations of lunar surface features are probably related to tidal forces that trigger the release of gases. According to Dr. Allan A. Mills, a University of Leicester astronomer, the escaping gasses could stir up clouds of dust, which he calls moon smoke.

These dust clouds could so scatter sunlight or perhaps produce electric discharges as to create brief eruptions of light. tidal effect of Earth's gravity tugging at the moon is one important scientific results of the Apollo explorations. Seismometers left by the astronauts found that moonquakes occurred most frequently when the moon came closest to Earth each month. Mills has noted that the 1,400 reported transient lunar phenomena over the years also occurred most frequently when the moon was at the perigee of its orbit, or closest to Earth. Mills reviewed the likely explanations for these lunar phenomena in an article published recently in the Journal of the British Astronomical Association.

A summary of his conclusions also appeared in the June 12 issue of the British journal Nature. Although some of the reported episodes were undoubtedly atmospheric, physiological or instrumental 'illusions, Mills and other astronomers said that many of the observations were of real events. They generally cover an area about 10 miles wide and last an average of 20 minutes. No permanent changes have been observed on the lunar surface after such an event. About 300 of the events have occurred at Aristarchus, a 23-mile-wide crater with majestic cliffs.

In 1958, Nikolai A. Kozyrev of the Pulkovo Observatory at Leningrad created a stir when he reported seeing a -long reddish from the central peak of Aristarchus. From a spectrograph of the event, he determined that the light was caused by the emission of low pressure gas. In 1963, astronomers at the Lowell Observatory at Flagstaff, saw red and pink patches of light in the region of Aristarchus. EVEN outgassing more came conclusive from evidence 15 of lunar Apollo sensors that radioactive radon emissions, the most active being at Aristarchus.

This indicated to scientists the presence of other gases necessary for transporting the radon to the surface. On July 4, the most recently reported transient lunar phenomenon was at Alphonsus, another crater known for these mysterious occurrences. Winifred S. Cameron, who catalogues such events, said an amateur astronomer in Florida noticed an unusual dark patch in Alphonsus. Two months ago, she said, a mist was observed at Piton, a mountain in the Mare Imbrium.

Most of the transients seem to appear in the Social Worker Wants Her Reduced! CHIPPEWA FALLS, Wis. (AP)-A letter from Chippewa county social worker Jane Emerson may have made labor bargaining history. She asked county supervisors for a salary cut of five cents an hour to allow her to qualify for a Federal Housing Administration mortgage loan. She said the five cent reduction, amounting to a loss of $90 a year, would make her eligible for a five percent FHA loan. Amused members of the county's personnel negotiations committee took no action on the request, but suggested Emerson take time off from work to reduce her income.

One member of the committee suggested Emerson's letter be framed and saved for contract bargaining time. FREE SPINAL EXAMINATION SATURDAY JULY 19TH DR.

Alphonsus and Plato, or around the rims of lunar basins, like Imbrium, Cameron said. She is affiliated with the National Space Science Data Center, operated by the National Aeronautics and Space Administration at Greenbelt, Md.

Long ago, astronomers assumed that these transients were volcanic eruptions. But no fresh lava regions have been seen on the moon either by telescope or in spacecraft photography. Mills, in his article, ruled out another possible explanation. He said that bombardment of the lunar surface by protons in the solar wind was too weak to produce luminescence. Comparing the epicenters of moonquakes and transient phenomena several years ago, Dr.

Barbara M. Middlehurst, formerly of the Lunar Science Institute at Houston, found that the phenomena occurred almost vertically above regions of shallow quakes. This association indicated that the quakes could be the force initiating outgassing through faults and fissures. MILLS goes further to dust propose above that the escaping gas blows the lunar surface and sunlight scattered by the dust particles accounts for the bright glows. He conceded that the scattering of light by moon "smoke" is an incompletely understood phenomenon.

And it does not explain phenomena seen in regions of the moon that are in darkness. Another mechanism-triboelectric chargingmay thus also be at work, Mills said. That is, friction from the movement of gas-borne dust produce electrostatic discharges in much the same way volcanic eruptions on Earth often generate lightning. Middlehurst said that Mills' explanations were reasonable." PEARLRIDGE CENTER 487-6441 after INVENTORY Far Eastern SALE STORE HOURS: MON-FRI 10:00 a.m. to 9:00 p.m.
