Meteorite holds clues to organic chemistry of the early Earth: study
PhysOrg Thu, 09 Jun 2011 11:04 AM PDT
Carbonaceous chondrites are a type of organic-rich meteorite that contain samples of the materials that took part in the creation of our planets nearly 4.6 billion years ago, including materials that were likely formed before our solar system was created and may have been crucial to the formation of life on Earth. The complex suite of organic materials found in carbonaceous chondrites can vary ...

2011 International Meteor Conference
International Meteor Conference
Sibiu, Romania, September 15-18
This year's International Meteor Conference (IMC)---the 30th edition already!--will take place in the historical city of Sibiu in Romania, from September 15 to 18, 2011. The standard early registration fee, including full board,
has remained unchanged from last year at 155 EUR. More details on this IMC can be found at

We also wish to point interested meteor workers attention to the fact that the period in which the early registration
fee is applicable expires at the end of the month. From July 1 onwards, the registration fee will be 170 EUR.
Every year, the IMC is an exciting event where meteor workers from all over the world meet and exchange their 
experiences. Make sure not to miss it!

Meteor Activity Outlook for June 11-17, 2011
During this period the moon reaches its full phase on Wednesday June 15th. At this time the moon will lie opposite the sun and will be in the sky all night long. This weekend the waxing gibbous moon will cause problems while above the horizon. Once it sets during the late morning hours, a small opportunity will exist for viewing meteor activity between moon set and dawn. The estimated total hourly rates for evening observers this week is near two as seen from the northern hemisphere and three as seen from the southern hemisphere. For morning observers the estimated total hourly rates should be near seven from the northern hemisphere and seventeen as seen from south of the equator. The actual rates will also depend on factors such as personal light and motion perception, local weather conditions, alertness and experience in watching meteor activity. Evening rates are reduced due to moonlight.
The radiant (the area of the sky where meteors appear to shoot from) positions and rates listed below are exact for Saturday night/Sunday morning June 11/12. These positions do not change greatly day to day so the listed coordinates may be used during this entire period. Most star atlases (available at science stores and planetariums) will provide maps with grid lines of the celestial coordinates so that you may find out exactly where these positions are located in the sky. A planisphere or computer planetarium program is also useful in showing the sky at any time of night on any date of the year. Activity from each radiant is best seen when it is positioned highest in the sky, either due north or south along the meridian, depending on your latitude. It must be remembered that meteor activity is rarely seen at the radiant position. Rather they shoot outwards from the radiant so it is best to center your field of view so that the radiant lies at the edge and not the center. Viewing there will allow you to easily trace the path of each meteor back to the radiant (if it is a shower member) or in another direction if it is a sporadic. Meteor activity is not seen from radiants that are located below the horizon. The positions below are listed in a west to east manner in order of right ascension (celestial longitude). The positions listed first are located further west therefore are accessible earlier in the night while those listed further down the list rise later in the night.
The following shower is expected to be active this week:
The wide Antihelion (ANT) radiant is now centered at 18:16 (274) -23. This area of the sky lies in northern Sagittarius near the faint star 11 Sagittarii. This radiant is best placed near 0200 local daylight time (LDT), when it lies on the meridian and is located highest in the sky. Due to the large size of this radiant, any meteor radiating from southeastern Ophiuchus, Sagittarius, Scutum, Serpens Cauda, or eastern Scorpius could be a candidate for this shower. Rates at this time should be near one per hour as seen from the northern hemisphere and two per hour as seen from south of the equator. With an entry velocity of 30 km/sec., the average Antihelion meteor would be of medium-slow speed.
As seen from the mid-northern hemisphere (45N) one would expect to see approximately six sporadic meteors per hour during the last hour before dawn as seen from rural observing sites. Evening rates would be near one per hour. As seen from the mid-southern hemisphere (45S), morning rates would be near sixteen per hour as seen from rural observing sites and two per hour during the evening hours. Locations between these two extremes would see activity between the listed figures. Evening rates are reduced due to moonlight.
The list below presents a condensed version of the expected activity this week.
Rates and positions are exact for Saturday night/Sunday morning.
Antihelion (ANT) 18:16 (274) -23 Velocity - 30km/sec
Northern Hemisphere - 1 per hour Southern Hemisphere - 2 per hour
Clear Skies!
