Still requesting reports from eye-witnesses!

Here's the good news:
Ernie Iverson's All-Sky Camera in Carson California
captured an image of this fireball on his video!!

Jim Gamble contacted Ernie within an hour of my post
and alerted him to check his video. Being a day-time
fireball it was difficult to find, at first, but the
brightest part of the flight was definitely captured.

Ernie used a program to determine start and ending
azimuth and elevation readings. And Rob Matson used
these numbers to run calculations which generated
graphs depicting a range of predicted Bolide Velocity
and Bolide Azimuth. Everyones efforts resulted in
confirming that the fireball passed over San Diego
County, maybe as far south as Chula Vista, or even
Tijuana.

Now here's the bad news:
Still no report of a sonic-boom.
It's possible that a sonic-boom occurred over Baja
California and was not reported in this country.
Also, we need more eye-witness reports!
Just one more eye-witness or new video would help us
constrain the wide ranges in our calculations.

Hard to believe that with all of the meteor observers
in this area and we can't find any more eye-witnesses.
Unfortunately, this was a day-time fireball. Had this
event occurred at the same time, but in January,
LA/San Diego rush-hour would have been treated to a
great light-show, and it would have been featured in
all the news wires and TV with "video at 11"!

Looking forward to making one more "UPDATE",
one with all "good news".

With best regards,

(meteorobs) Daytime Fireball in SoCal seen from LA

Just received a report from one of my team members who
witnessed a daytime fireball at 4:55PM PDT while
driving east at the intersection of 118Fwy and Tampa
Blvd. in the north end of San Fernando Valley.
Obviously bright (being a daytime fireball) but
remarkably green-colored (in a sky that is still blue
and only 5% clouds).

Unfortunately, the observer was unable to see the
termination, having the fireball "vanish from sight"
while it was still traveling "down to the SE".

I apologize for the lack of detail in degrees elev and
all, but I'm going straight to requesting if anyone
has heard of any reports of a sonic boom in the
Riverside - San Diego County area of Southern CA?

This just occurred so this is all the info' that I
currently have.

Hope to hear from some other observers, soon.
Bob V.

Have just put in a request for videotape review from
our L.A. Sandia all sky camera location and hope to
have an answer later tonight. The operator was not in
at the time I called. He normally runs videotape 24/7
but also has Sentinel auto-detect. It's possible that
if the event was bright enough, Sentinel may have
auto-triggered on it. We'll see.
