BREAKING NEWS...UPDATE To 08Aug2011 Ohio Fireball Reports To ELPALLSKY... Ontario Canada Fireball Cameras Capture Possible Meteorite Producing Fireball Over Ohio

NASA Releases Ohio Fireball Data Indicating Meteorite(s) May Be On The Ground In Ohio

Aug 17, 2011, at 9:46 AM, Cooke, William J. (MSFC-EV44)
On August 8 at 1:22 Eastern Daylight Time, 4 all sky cameras belonging to the Southern Ontario Meteor Network detected a fireball entering the atmosphere 54 miles above Lake Erie (80.944 W, 41.945 N), moving SSE at 25 km/s (55,900 mph). Decelerating rapidly, the meteor was last tracked north of Gustavus (80.667 W, 41.411 N), moving at approximately 10 km/s. Altitude at this point was 38 km (23.6 miles). There is high confidence that this meteor produced meteorites, based on the following indicators:
(1) Deep atmospheric penetration (last tracked to 38 km altitude before it passed out of camera field of fiew. It certainly went deeper)
(2) Significant deceleration
(3) There was a doppler radar signature (KCLE) 2-3 minutes after the event, which indicates debris falling through the atmosphere
Darkflight calculations yield results consistent with the dopper returns. Calculated impact locations as a function of mass are:

1 gram: 80.5027 W, 41.3824 N
10 grams: 80.5163 W, 41.3379 N
100 grams: 80.5158 W, 41.2910 N
1 kilogram: 80.5074 W, 41.2440 N

Brightness/infrasound measurements put the meteor mass in the 10 kilogram range. Fragments are anticipated to be less than 100g in mass.
Attached graphics include a composite of the meteor as seen by the Orangeville camera, a map showing the darkflight impact locations, and a segment from the KCLE radar with the meteor begin and end points labeled.
It is requested that anyone finding fragments of this meteorite note the location of the find and contact this office. Please observe the wishes and rights of all property owners.

Possible Large Green Meteor Fireball British Columbia, Canada 15AUG2011

Two Initial Reports Of A Possible Large Meteor Fireball Event BC Canada ~9:45-10:30 p.m. PDT 15AUG2011

Email From:

Horst U.-British Columbia Province, Canada:

Hello,
Was searching for the subject event and came across your website.
I was at home on the deck. It was a clear sky; the moon had not fully risen yet.
The object came from North-west, and while going South-east ( away from me ) the angle of the arc increased, i.e. it didn’t stay at the same height. It took about 4 seconds for the object to go ( what appeared to be ) almost vertically down when it reached my event horizon. My house is 350 meters above sea level.
There was no streak or smoke trail & no fragmentation.
The fire ball was extremely bright; I would say 20 times brighter than Venus.
Years ago, the international space station flew by ( west to east ) right after sunset. The space station was about the same size but not nearly as bright as the fire ball last night and also the apparent speed was much slower.
I established the trajectory by plotting the angle the house sits with respect to South ( using Google map close-up ), and added about 10 degrees because the object when it crossed over was not perpendicular to the street line ( equal the deck line ). In other words, it went a little bit to the left.
I would guess that the object hit the ground somewhere along the yellow trajectory line ( see attachment ).

I hope my observation is of interest to you.
Your response is greatly appreciated.
Best regards,
Horst U

Did anyone see large green fireball lastnight? Around 10-10:30? Over East Vancouer Island. Look like it came really low to ground.
