Quadrantids: The San Francisco Chronicle has an article today, "Intense meteor shower could illuminate Bay Area skies early Jan. 4." It tells about a paper by Peter Jenniskens who predicts the Quadrantids will produce "as many as 150 flashes per hour streaking through the darkness between 1 a.m. and dawn on Sunday, Jan. 4," and who has linked this meteor shower with 2003 EH1.
According to Jenniskens, a Japanese astronomer and comet hunter named Ichiro Hasegawa first calculated that the Quadrantid meteors must have come from a comet that Chinese, Korean and Japanese astronomers had described brightening in what must have been a violent explosion that occurred between Dec. 31, 1490, and Feb. 12, 1491. [And] the first observations of the Quadrantid meteors were recorded by an Italian astronomer on Jan. 2, 1825.
2003 EH1 is an unusual near-Earth asteroidal object discovered by Brian Skiff at LONEOS on
March 3rd (MPEC 2003-E27), and last reported seen April 23rd. It travels a comet-like eccentric (e=0.618) and highly-inclined (70.8°) Jupiter-approaching path. From its brightness, EH1's diameter is roughly estimated at 1.5 km. (0.97 mile), and possibly up to 2.7 km. (1.7 miles).
Meteor catch: An article at the Indianapolis Star today tells about, and shows, the December 1st find of a rock "4 or 5 inches around" that had burned into stack of foam insulation at a house construction site near Shelbyville, southeast of Indianapolis, Indiana, "embedding itself 7 inches deep." This story was picked up by the Associated Press and is appearing in slightly different form on many news sites, including WRTV Indianapolis today.
The Wednesday Daily Orbit Update MPEC carries no observations of objects recently in view that have impact solutions, which is not an unusual situation during the time of the full Moon. 2003 WW26 was removed from the European Spaceguard Central Node Priority List today as going out of view after today for most observers, and 2003 WT153 went out of view after the 1st of this month.
