New images of Jupiter’s pole show enormous, gorgeous storms

NASA’s ‘Juno’ spacecraft was launched in 2011 and entered Jupiter’s orbit in July 2016. Tasked with studying the gas giant, early data from Juno suggest that among other insights, scientists had underestimated the intensity of Jupiter’s ‘mammoth, lumpy’ magnetic field.

Juno is on a polar orbit around Jupiter, passing close to the surface every 53 days. Each time it makes a pass, it collects data using various instruments, including its ‘Junocam’ camera. It takes around one and a half days to send back 6MB of data. 

Taken in Jovian orbit from a height of 32,000 miles, this image show huge earth-sized storms raging on Jupiter’s south pole. Each storm is made up of cyclones that measure 600 miles in diameter.

And we thought Seattle’s weather was bad…

Yep, That’s an OCF Magnet at The South Pole.

05 Feb

Back in 2009 we had a little game going wherein people left Strobist OCF magnets at various places around the world. Some were dropped off and tweeted for the first finder to claim. Others were just placed and photo’d in what can only be considered some pretty impressive spots. One might say it even got a little competitive.

Five years later, reader Sebastian Stewart has just dropped an OCF A-Bomb. He has placed an Off-Camera Flash magnet at the South Pole.

Sebastian is on a team of NASA scientists who measure atmospheric conditions by shooting (frickin’) lasers into the air and measuring the returns they get from various particles. As such, he travels around the globe. Which makes any OCF challenges a bit easier, natch.

Says Stewart:

I finally returned to the South Pole for work, I actually just returned to the states after about seven weeks of travel, split between New Zealand and Antarctica.  I’m only stateside for a few weeks before jetting off to SE Asia for a month of more work.

I was at the Pole replacing an old legacy instrument that was barely hanging on.  The new instrument I replaced it with is unique in it’s ability to differentiate between spherical and non-spherical particle shape, and give us some information about what exactly is reflecting the laser light back to the instrument.  It’s much more reliable and should provide a great data set for the coming future.

I remembered to bring your OCF magnet to the Pole with me!  I attached two photos for you – one of me holding the magnet in front of the geographic pole sign (the actual 90?S latitude point – the Earth’s axis) and one at the ceremonial pole ~30 feet away (solely for photos and PR stuff – you can see the flags of the Antarctic Treaty signatory nations in the reflection).  I am sad to admit that the sign was aluminum so I couldn’t stick the magnet to it, but I did my best at holding it still for the photo.

Magnetic South Pole, my ass. Aluminum? Pfft.

As it happens, Stewart has availed himself of some pretty cool travel photography opportunities as a result of his far-flung atmospheric science. You can see his work at sebastianstewart.com.

Many, many thanks for the photo evidence, Stewart. Lotsa luck to anyone trying to top that. And trust me, there have been some worthy efforts to date. Just none quite this cool.

Which Begs the Question…

You may find yourself wondering, what was the previous high-water mark?

There were some cool placements, including some classified locations not generally available to the public. Military bases in deserts, that sort of thing. But I previously had thought this one all but unbeatable:

That’s not just any Mercedes AMG. That one happened to be parked at One Infinite Loop in Cupertino California back in the day. No license tag, tho. Hmm.

And that trunk is not magnetic either. But chewing gum works. Name withheld (and metadata stripped) to protect the innocent.

I had thought Jobs’ car as an OCF placement to be unbeatable. I was wrong. But still, I don’t see anyone topping the South Pole.

Using a super clamp to mount your Zoom H4n on your boom pole – DSLR FILM NOOB

18 Nov

www.dslrfilmnoob.com Super Clamps are handy little devices. You don’t have to use them with a manfrotto magic arm for them to come in handy. One Great use for them is mounting your zoom h4n. Using the stud that comes with your super clamp you can mount a threaded cold show adapter rcm.amazon.com or threading it into the super clamp stud: rcm.amazon.com Either way provide you with a great way to mount your zoom h4n to your boom pole. The zoom h4n is light enough that you wont be over taxed by the extra weight, and with the multiple mounting options on a super clamp you could always mount a wireless transmitter/receiver to send audio out or bring it in from other sources. When i have to operate the boom mic from long distances I often attach a wireless transmitter to send my audio back to the camera. That way my 7d has a good solid sync track for dualeyes to work with. Equipment used in this video: Canon t2i canon 35mm f1.4 Zoom h4n Cowboy super clamp and manfrotto super clamp Sennheiser g2 wireless transmitter
