Solar Activity and the Southern Delta Aquarid Meteor Shower

Source - Space Weather News for July 28, 2010: http://spaceweather.com

SOLAR ACTIVITY PICKS UP: Earlier today, magnetic fields looping over the sun's southeastern limb became unstable and erupted. The blast produced a bright, towering prominence that attracted the attention of amateur astronomers around the world. Meanwhile, on the sun's northeastern limb, a big new sunspot is emerging and it is crackling with C-class solar flares. Visit http://spaceweather.com for images and movies.

METEOR SHOWER: The University of Western Ontario meteor radar is picking up strong returns from the Southern Delta Aquarid meteor shower, which peaks on July 28th. Sky watchers (particularly in the southern hemisphere) should be alert for meteors between about 10 pm and dawn. "Visual rates could be as high as 20 per hour," notes Bill Cooke of NASA's Meteoroid Environment Office, "although glare from the nearly full Moon will make many of the fainter meteors difficult to see."

Are We Alone - What's Your Poison

“Aspirin and Old Lace?” Okay, it would take a bottle full of pills in a glass of elderberry wine to really harm you, but aspirin can be deadly. So can too much of anything, including water. Dose is key in toxicology, after all, but there are some poisons that can do deadly work in tiny amounts.

Hear about the chemistry of poisons … why Botox may freeze your emotions as well as your face… which animal is most lethal to humans… and how 19th-century poisoners got away with murder – until the birth of forensic science.

Seattle Astronomical Society meeting - Wednesday, July 21, 2010

The next SAS meeting which will be on Wednesday, July 21, so that all can plan ahead for attendance. SAS membership is unnecessary to attend the meeting, so all of our group members who are not SAS members will be welcome. The topic promises to be really fascinating.

Topic: Real Time Spectroscopy with RSpec

Presented by: Tom Field

At the next meeting, Tom Field will give a presentation of his new program "RSpec" that does real-time astronomical spectroscopy. He will review a bit of the history and science around spectroscopy and then discuss various projects that amateurs can undertake. As many members know, spectroscopy is one of the primary tools that are used in astronomical research. If you've got a DSLR, webcam, or classical CCD and a even a small telescope, RSpec and a simple grating is all you need to get into this interesting aspect of astronomy.

Tom says, "Spectroscopy isn't rocket science, but it is one of the last frontiers for amateurs to get involved in on a large scale. It's exciting to be able to actually see the composition of stars with some simple backyard gear. And, once you have some hands-on spectroscopy experience, you'll find that a lot of the articles in Sky & Telescope and on the web take on a whole new meaning in light of your new understanding of the field."

Solar Activity Surges on the Eve of South Pacific Eclipse

Source - Space Weather News for July 10, 2010: http://spaceweather.com

A LIVELY SOLAR ECLIPSE: Fast-growing sunspot 1087 is crackling with C-class solar flares. A spectacular eruption recorded by the Solar Dynamics Observatory is featured on today's edition of Spaceweather.com. This surge in activity comes on the eve of a total eclipse of the sun over the South Pacific. Will eclipse chasers see material blasting away from the sun when the Moon hides the blinding stellar surface? It's a possibility. Stay tuned to http://spaceweather.com for updates and pictures from the path of totality.

SUNSET CONJUNCTION: Look west at sunset. Venus is passing by 1st magnitude star Regulus. They're only a little more than a degree apart. Bright Venus catches the eye first. As the glow of sunset fades, Regulus pops out of the twilight a little below Venus. The view through binoculars is superb.

Are We Alone - Rend Me Your Ears

Shh - can you keep it down? Nope. Not unless you want to do away with civilization. Our buzzing, humming, whirling, machine-driven world is a poster child for technological progress, right? As is hearing loss. It’s driven one man to search the world for silence. We’ll hear what he didn’t hear, and what Einstein predicted we should hear in deep space, where gravitational waves may reveal the hidden sounds of the universe, including the birth of black holes.
