Cometary Sunday

BRIGHT MORNING COMET: Comet NEOWISE (C/2020 F3) is doing something very rare: Shining through the rosy glow of dawn. “How many times in your life can you say ‘I saw a comet at dawn’–and really mean it?” asks Petr Horálek of the Czech Republic. “It happened to me this morning!” Horálek took this picture just before sunrise over Proseč u Chrudimi:

“Pretty clear skies allowed me to capture Comet NEOWISE from the ephemeral moment of its rising to the moment I was able to see it with naked eyes–even if still very hardly–on July 4th July,” says Horálek.

Yesterday, July 3rd, Comet NEOWISE passed by the sun near the orbit of Mercury. Intense solar heating boosted its brightness to magnitude +1 (now +2), allowing it to be seen despite its close proximity to the sun. This development has turned NEOWISE into one of the most remarkable comets in years.

In Stixendorf, Austria, Comet NEOWISE was visible from the very moment it peeked above dark clouds hugging the eastern horizon. Astrophotographer Michael Jaeger recorded this video:

A tracked exposure by Jaeger shows the extent of the comet’s magnificent fan-shaped tail: image.

Comet NEOWISE is just getting started. It is barely visible to the naked eye now only because it has to compete with the glow of dawn. The situation will improve in the days ahead as NEOWISE moves into darker skies. If it retains its current luminosity, the comet should put on a very good show indeed. Set your alarm for dawn!

    Within Bellingham city limits, it’s illegal to BLOW OFF CONSUMER FIREWORKS!

    Last night I closed the bedroom window and turned a fan on HIGH to block out the COMBAT LEVEL NOISE!

    What the hell is the matter with people? The poor, frightened animals, the people with PTSD!!

    A friend emailed me this morning, reporting that in his cul de sac M80s were ignited that set off car alarms. His dog, Chloe, shivered and shaked. He’s a Vietnam Veteran for Peace — and saw no reason to wave the flag or be a *proud* American.

    A friend who lives *out in the county* where the fireworks were much worse, said one of her neighbors bragged that they had spent $2,000 on FIREWORKS. That’s not a typo! She said “too bad they didn’t blow up their billboard-sized Trump sign!

    It is a beautiful day, however. So…I’ll go with the for now!

      In the bad old days Pullman used to have the complete fire department, police department and police auxiliary on duty for night of July 4th. But then anyway some fireworks caught a roof on fire, totalling the house.

      Now personal fireworks are only legal on the 3rd & 4th. These must purchased in Pullman, which regulates the types sold. The big stuff is just for the Chamber of Commerce sponsored pro show.

    Could microplastics act as a bioaerosol that would qualify as a fomite? There are microplastics everywhere! In every nook and cranny.

    Aerosoled MPs may provide insight on why some regions experienced the Covid outbreak with no trace or history of an infected person visiting the region????

    Another hot day. I needed to drag the hoses around yesterday, it’s today and I still haven’t done it. I just don’t feel like it. I have to fill the bird bath then pull the hose out to the pool BECAUSE I HAVE TO BACKWASH THE DAMN THING YET AGAIN!

    I posted a picture of the backyard with the pool, taken from my roof, and one of Pete’s friend’s knows someone that might be interested in the pool. I won’t hold my breath though.

    I hate these down-in-the-dumps days. I’m glad I don’t have a lot of them. 😦

    An epidemiologist, an ICU doctor and a scientist all walk into a bar.

    I’m just kidding, they know better.

    Maybe it was love of beer that caused the

    Rye beer?
