C/2001 HT50 (LINEAR-NEAT) imaged 2 Nov. 2003 by Begues Obs. Pepe Manteka at Begues Observatory early yesterday caught this image of
C/2001 HT50 (LINEAR-NEAT).



Bits & Pieces

Precovery:  MPEC 2003-V05 yesterday announced that Maik Meyer had found PHO 2003 FC5 in images from NEAT's Mt. Palomar telescope from 16, 18, and 26 August and 22 September 2002. This object was discovered by LINEAR on 27 March 2003 and, from its brightness, is estimated to be roughly 770 meters/yards wide. Maik Meyer tells A/CC that, "Although [2003 FC5] was quite faint, it was clearly visible in two days and for another two days I used Astrometrica's superb track&stack feature to get clear data."

1937 UB Hermes:  Tomorrow 1937 UB Hermes will make its closest Earth approach this year, at about 18.6 lunar distances. Rafael Ferrando sent this image below of the famous visitor (shown as a multi-frame streak) from Saturday night at Pla D'Arguines Observatory in Spain.

Comet news:  The Minor Planet Center issued update MPECs today for ten comets under recent observation, from C/2003 R1 (LINEAR) through COMET P/2003 U3 (NEAT).

Meteor news:  The Geological Society of America (GSA) has a news release today, "Extraterrestrial Enigma: Missing Amino Acids In Meteorites" (first seen at EurekAlert). This comes from the GSA Annual Meeting in Seattle, Wash., where a paper has been presented on "The significance of protein amino acids in carbonaceous meteorites" by Michael H. Engle and Stephen A. Macko (abstract).

Uttar Pradesh event: A Press Trust of India story at rediff.com today, "Meteorite-like object lands in UP village," says people in western Uttar Pradesh "claimed to have seen the object, weighing about 19kg, falling from the sky around 1900 IST with a loud noise" Sunday, and found it in a crater "approximately three feet deep."

More solar blasts:  Space.com reports today that "The Sun cut loose with three severe flares in less than 24 hours through Monday morning," which could result in more aurora at lower latitudes overnight and especially tomorrow night. From last week's extensive aurora displays, Alan Fitzsimmons of Queen's University Belfast has posted photos he took Wednesday night in Northern Ireland. See also SpaceWeather.com's October Aurora gallery with several pages starting from October 29th from around the world and across the southern U.S.

A/CC's close coverage of 1937 UB Hermes developments has now been consolidated as
"1937 UB Hermes Day-by-Day."

Risk monitoring
3 Nov.

Today JPL put 2003 UX34 back on its Current Impact Risks list, following new observations reported in today's Daily Orbit Update MPEC (DOU) from early yesterday from the Spacewatch 1.8m telescope.

The DOU carries observations of 2003 UQ25 from yesterday morning from the Spacewatch 1.8m and from Desert Moon Observatory in New Mexico, and now both JPL and NEODyS have removed this object.

A set of six observations spanning less than five minutes is reported from the 2.5m Isaac Newton Telescope at La Palma in the Canary Islands for 2003 UO12 from Saturday night, and more than seven hours later the Spacewatch 1.8m caught it from Arizona. Today both risk monitors lowered their risk ratings for this small object with a single impact solution, in the year 2067.
