Did I mention on here, one of our former administrators, Lori had her Georgia house hit by a small meteorite. It punched a hole in one portion of their ceiling and went out another...  :o They went out the next day but could never find the fragment.

Barb, I may already have mentioned that we had a similar experience here back in February.  We had just completed getting a metal roof on the house the previous Friday, and that following Monday received a hard hit to the roof from something that we could never locate the remains of. 

Another blessing of putting the metal roof on was that when the solar panels were removed during the work, we discovered that squirrels had chewed the covering off of two cables that would have ignited the roof had they touched together.  Fortunately, this was corrected as soon as it was discovered, and of course the metal roof now is too slippery to allow squirrels to nest underneath the solar panels.  Readers who have solar panels and an asphalt or cedar shake roof may want to have the roof inspected periodically.

Wow RR - that is fortunate you decided to put a metal roof on your house, when you did.  :o
That is useful data - thanks.

Man videos 'meteorite strike' in Cairns, Australia; loud explosion heard

https://www.sott.net/article/364137-Man-videos-meteorite-strike-in-Cairns-Australia-loud-explosion-heard

The city's "big bang" mystery continues to deepen with residents split on whether it was caused by a meteorite, gas bottle explosion, electrical transformer failure or sonic boom.

Beginning with the latter theory, a single FA-18 Hornet was heard flying loudly over Cairns on Sunday night, with a Department of Defence spokesman confirming it landed at Cairns Airport while carrying out a training exercise from RAAF Base Townsville.

But no jets were operating late on Saturday night when a god-almighty "explosion" was heard across the city.

As for the gas bottle theory — the most popular on social media — emergency services had no report of any such activity despite speculation it was the product of juvenile delinquents running rampant at Jensen St in Manoora.

The Cairns Post was called by an anonymous man trying to sell CCTV footage he swore showed a jolt of light shooting up a power pole and causing the ensuing aftershock.

"I'm sure this is the location of what caused that massive bang though," he said.

Just wonder if there will come a point when the fireballs and debris showers are so dense that we'll need hard hats?

Public Service Reminder from the Chelyabinsk event: Never stare at a meteor or comet, as a terminal explosion could cause corneal damage, as it did to many in Russia.

From Wikipedia:

Quote
Russian authorities stated that 1,491 people sought medical attention in Chelyabinsk blast within the first few days.[3] Health officials said 112 people had been hospitalised, with two in serious condition. A 52-year-old woman with a broken spine was flown to Moscow for treatment.[24] Most of the injured were hurt by the secondary blast effects of shattered, falling or blown-in glass.[24][71] The intense light from the meteor, momentarily 30 times brighter than the Sun,[47] also produced injuries, leading to over 180 cases of eye pain, and 70 people subsequently reported temporary flash blindness.[72] Twenty people reported ultraviolet burns similar to sunburn, possibly intensified by the presence of snow on the ground.[72] Vladimir Petrov, when meeting with scientists to assess the damage, reported that he sustained so much sunburn from the meteor that the skin flaked only days later.[73]

Short minute long film of the immediate aftermath of the front end of a sturdy vehicle taken out by an exploding meteorite that appears to have left a 2' diameter fragment.  Glass is broken, camera explodes, front tire is flat, hole where vehicle front end used to be.
