The Asteroid/Comet Connection's
daily news journal about
asteroids, comets, and meteors

Today's issue status: done

Cover: Erich Meyer took advantage of last night's lunar eclipse to pick up the dim (mag. 21) and fast-moving 2004 HG12 at Linz Observatory in Austria. Just large enough to be categorized as "potentially hazardous" (JPL H=21.97), it had been reported only once since April 22nd, back on the 27th, and goes out of view this week. Twenty 60-second exposures are stacked on the object's motion, so stars appear here as bumpy streaks.

Details: 2004 HG12. 2004 05 04.84 UT. +21mag. 20x60-sec exposures. Motion 6"/min. Field 11'x16', North up. 0.60m f/3.3 Reflector + CCD. 540.

News briefs

Southwest meteor:
All-sky cameras at Sandia National Lab in Albuquerque, N.M. and on Jim Gamble's roof in El Paso, Texas 220 miles (350 km.) due south, both caught a bright meteor at 1:10am this morning. Below is Jim Gamble's composite image of the event in the northwest quadrant of the sky, shot from a camera pointed down at a hemispherical mirror (description). The A/CC-assembled animation has parts of frames from both cameras, reoriented so the left-hand Sandia view

W. Australia fireball: The Australian Broadcasting Corporation today reports speculation that the April 30th Perth meteor (report) may have landed in the ocean 100 km. west of Geraldton.

Comet C/2001 Q4 (NEAT) from
Desert Eagle Obs. 4 May 2004

Now in northern skies: Bill Yeung caught comet C/2001 Q4 (NEAT) at Desert Eagle Observatory in Arizona "just 10 degrees above SW horizon" at 8pm MST (not MDT) last night. This 3-sec. exposure (18" f/2.8 ST10XME) shows signs of what have been called dust "shells," "waves," or "hoods" in images from the southern hemisphere (see Lovejoy and Masi and Mallia). Clay Sherrod also reported C/2001 Q4 last night from Arkansas by telescope and binoculars. See finder chart and a article today.
