   EVENTS NEXT MONTH (12):  
   
Sputnik 1 Launched - October 4 @ 01:00
On this day in 1957, the Soviet Union launched the first artificial satellite, Sputnik 1, into orbit. The launch threw a scare into the West and completely overshadowed the official rollout of the Avro Arrow interceptor aircraft.
   
Full Moon - October 6 @ 15:47
The Moon is most-opposite the Sun in the sky, rising as the sun sets.
   
Kepler's Supernova - October 8 @ 01:00
On this day in 1604, the famed astronmer Johannes Kepler spied a supernova in Ophiuchus. The second in about 34 years (see Tycho's Supernova, Nov. 15), and designated SN 1604, this detonation of a distant star was bright enough to be visible during the day. Thus far, it has been the last naked-eye supernova in the Milky Way. Its remnant is the subject of ongoing study.
   
Last Quarter - October 13 @ 06:12
A waning half-Moon is near the meridian (halfway across the sky) as the Sun rises.
   
Hurricane Hazel - October 16 @ 01:00
This powerful post-tropical storm moved into Ontario on this day in 1954 (71 years ago), dropping heavy rainfall and causing significant damage to the waterfront, in addition to flooding.
   
Loma Prieta Earthquake - October 17 @ 01:00
A major earthquake occurred just before the scheduled start of a World Series game, on this day in 1989. Among the many significant consequences of the quake were the heavy damage to the San Francisco-Oakland Bay Bridge, and the collapse of the double-deck Cypress Street Viaduct.
   
Happy Birthday Bill - October 19 @ 01:00
On this day, in 1964, Bill Demmery, the author of the MC-HOME suite, was born. This year, he turns 61.
   
Black Monday - October 19 @ 01:00
In 1987, on this day, a stock-market crash wiped out 22.6 percent of the Dow Jones Industrial Average, its biggest one-day drop ever, after an unprecedented period of growth.
   
New Moon - October 21 @ 00:25
The Moon is nearest the Sun in the sky and cannot be seen from the ground.
   
Black Thursday - October 24 @ 01:00
Signalling the beginning of the Great Depression, the Dow Jones Industrial Average dropped by 11 percent on this day in 1929, the beginning of many months of slides. Stock prices bottomed out in 1932. The Great Depression continued until the outbreak of war in 1939.
   
First Quarter - October 29 @ 04:20
A waxing half-Moon is near the meridian (halfway across the sky) as the Sun sets.
   
Hallowe'en - October 31 @ 01:00
This observance, originally called "All Hallows' Eve", and immediately preceding All Saints' Day, is a mostly-fun-filled celebration of the dead; a night when jack-o'-lanterns decorate doorsteps, and candies are handed out to canvassing children.
