The Tears of St. Lawrence are intensifying

While yesterday was the Feast of St. Lawrence, the Tears of St. Lawrence are to intensify today.

Your planet is moving through the debris field of a comet, Swift-Tuttle.  Over the next few days there will be more and more meteors and fireballs.   Spaceweather says that the best viewing will be before local sunrise when the constellation Perseus is high.    That’s why this annual meteor shower is also called the “Perseids”.

What’s happening in more prosaic terms?  Comet debris particles a few cm wide are hitting the atmosphere with an average speed of 59.6 km/s (133,350 mph).  The average magnitude of the resulting fireballs is -3.7, about as bright as Venus.   The Perseids produce more fireballs than any other meteor shower.  Swift-Tuttle has a huge nucleus–about 26 km in diameter, much larger than most comets.  Therefore, Swift-Tuttle produces more meteoroids, which produce fireballs.

I like the “Tears of St. Lawrence”.

Speaking of the Perseids, and speaking pf PANDEMICS, check out an engaging  “apocalyptic” series by Steven Konkoly.    The first two books are….

The Jakarta Pandemic – UK HERE.

“The unstoppable H16N1 virus rapidly spreads across the United States, stretching the fragile bonds of society to the breaking point. Schools close, grocery stores empty, fuel deliveries stop, hospitals start turning away the sick…riots engulf the cities. As hostility and mistrust engulfs his idyllic Maine neighborhood, Alex quickly realizes that the H16N1 virus will be the least of his problems.”

It goes on with The Perseid Collapse  – UK HERE.

Just trying to cheer you up!

And, for the rest of your space weather reports, I am delighted to report to you hams that your yellow star might be waking up a little.  Solar Cycle 25 is slowly coming on.   At Spaceweather there is a good shot of a sunspot, AR2770.

Also, a big space rock, 2011ES4, is going to whiz by at .3 LD, that is, about 115000 miles away, about 1/3 of the distance to the Moon.  Mark your calendar for 1 September.

    Jakarta Pandemic? I don’t have the book but we’ve got the real thing right here in the north-west corner of Java.

    Interesting. I had never heard that name for the Perseids before. Is Tears of St Lawrence the older of the names (I imagine it would be)?

  3. Your instinct seems right to me. It has an ancient feel, though it could be medieval.
