Professional meteor hunter Steve Arnold is asking home and business owners in central Maryland and southern Pennsylvania to check their security tapes from early Monday morning for evidence of the meteor that scores of residents across the region have been reporting.

Most reader reports to this Blog put the time between 1:00 a.m. EDT and 1:15 a.m., July 6, with many focused on 1:08 - 1:10 a.m. 

Arnold, co-star of the Science Channel's "Meteorite Men" program, is hoping to use the tapes to triangulate on the meteor and calculate its path. From that, he hopes to launch a search for any bits of the space rock that may have made it to the ground.

"That security camera footage is badly needed," Arnold told me in an email note. "I am optimistic, as there should be a few thousand cameras that caught it on tape. The key is to find at least three good camera angles to triangulate from. By 'good,' I don't necessarily mean the clearest, or in color, but ones that have physical objects visible in the distance so that when visiting the camera in person, with a compass, one can tell exactly where the fireball extinguished. This way a definite line can be drawn from the lens of the camera to the object and on the the point of 'redardation.' Three good lines intersecting gives us what we need."

Arnold also asked me to see whether the region's weather radar captured a trace of the falling meteor. I've asked the National Weather Service at Sterling to look into it.

Security camera footage has been used before to document fireball meteors. There are lots of them on YouTube. So, if you own or have access to security camera tapes in the region, check your Monday morning data for the flash. If you find something, you can contact me at frank.roylance@baltsun.com, or Steve Arnold at MeteorHntr@aol.com. Or, copy us both.
