Home/BlogDespite some clouds, I was able to capture time lapse video of Asteroid 2014 JO25 passing by last night. Nearly 2 hours of time exposure photos are compressed into 23 seconds, from 9:20 p.m. until 11:09 p.m. CDT (watch full-screen, and make sure the highest definition is enabled, 1080p):
The asteroid is traveling from near the left side toward the right. The clearest view, unobstructed by clouds, is near the end of the video.
The dumbbell-shaped asteroid was measured a few days ago by radar to be about 1 mile long, and was about 1 .5 million miles away from Earth at the time of the video.
Taken with a Canon 6D, Canon 200 mm f/2.8 lens at f/4.0, ISO2500, over 500 individual 10 sec exposures taken every 12 seconds, mounted on an Astrotrac star tracker, which in turn is on a Manfrotto geared head on a tripod.
Dr. Spencer
That was great time lapse! Thanks.
1.5 mega miles (6 times as far as to the moon) isn’t even close. I enjoyed the guitar challenge the second time around better.
Given the cross sectional area of the earth, I calculate there will be 140625 of those for every direct hit. 🙂
well, now, you just ruined all of the panic, didn’t you?
I’m feeling giddy today. Must be spring. : )
Yes but what number was that one…… 140624
panics on again
Harry, I can’t do all the heavy lifting here.
Roy…you didn’t spot any black holes or remnants of the Big Bang, did you?
Oh, sorry, you’d need a radiotelescope for that.
Is the west coast ready for another storm?

ren…”Is the west coast ready for another storm?”
We’re always ready for storms, ren. They are part of life around here, living near the Pacific Ocean.
What we are not ready for is another Little Ice Age but I fear one is coming.
How’s things going with the Sun?
Greenhouse gas warming easily swamps any cooling from a Maunder Minimum-like sun this century. Cooling by 2100 would only be, at most, 0.3 C below IPCC projections. We will not be entering another Little Ice Age.

WE can only hope those you cite are correct. The last thing we need or want is cooling. Warming is the way to go, with more CO2 to go with it.
Longer growing seasons and the atmospheric carbon to help it along.
3 B people who live in the tropics disagree. But hey, just keeping thinking only about yourself.
DA,
I live in the tropics. I don’t disagree with Lewis.
Maybe you can name at least one of the three billion people you quote.
In any case, the facts don’t change – no how many people claim that the temperature of a thermometer on the surface can be raised by putting more CO2 between it and the Sun, it stubbornly refuses to comply!
That’s your cue to deny, divert and confuse. Go for it!
Cheers.
David makes up stuff as he goes along.
Notice his constant requirement of citations is missing. But, going along for the ride, there are billions more who live in the tropics who have proven by their migratory patterns that they want less ice and snow and cold.
Most important are the farmers, none of which that I’m aware of, plant in the snow and ice.
Weird, Lewis — I cite the science all the time, more than anyone else who comments on this blog.
And you? Never ever that I’ve seen.
So you don’t get to judge. Stick to snark, Lewis — it’s the only thing you’re good at.
Flynn, you need to decide if you’re denying tropical warming or the greenhouse effect.
Or are you just thoughtlessly denying everything and anything?
The Sun will show who governs the Pacific.

The climate is very insensitive to changes in total solar irradiance, warming by only about 0.1 K/(W/m2). It is barely a factor in short-term climate change.
An active jet stream will be one ingredient helping to fuel multiple rounds of severe thunderstorms that could include tornadoes in April’s final week.
The first disturbance rippling through that jet stream will bring severe storms from the central Plains into the lower and middle Mississippi valleys midweek. Right behind that, another potentially more robust weather system could fire off more severe weather in the southern Plains Friday, which may then shift farther east into next weekend.

For the record. Would this be considered an Anthropogenic forcing?
“On 6 August 2014, the spacecraft reached the comet and performed a series of manoeuvres to eventually orbit the comet at distances of 30 to 10 kilometres (19 to 6 mi).[13] On 12 November, its lander module Philae performed the first successful landing on a comet,[14] though its battery power ran out two days later.[15] Communications with Philae were briefly restored in June and July 2015, but due to diminishing solar power, Rosetta’s communications module with the lander was turned off on 27 July 2016.[16] On 30 September 2016, the Rosetta spacecraft ended its mission by hard-landing on the comet in its Ma’at region.[17][18]”

Dr. Spencer, I’ve been following you for many years and I must say that you time lapse photos of the asteroid is outstanding!
Hope to get some real good pictures myself on August 21 of this year.
Liked the time lapse.
Do you think the storm named Arlene in the Atlantic ever actually had any ‘tropical’ characteristics?
I wonder will my quartz crstals have extra healing power when the asteroid is near? Maybe we can collectively heal climate change as one concious effort… who is in? lol.
Areas from Romania to Moldova and Ukraine were the latest in Europe to receive rare and disruptive April snow this week.
Unusually cold air plunging southward and connecting with a storm tracking eastward across central Europe allowed the snow to unfold late this week.
“The storm initially led to accumulating snow for Germany, southern Poland and into the mountains of the Czech Republic earlier this week,” AccuWeather Meteorologist Tyler Roys said. “Even Vienna, Austria, received snow.”

With the various ice ages, I side with more CO2 too. Can’t hurt. It’s obviously not a primary driver. And let’s face it, we’re one huge cinder cone or comet hit away from billions dying. We know such events happen. More CO2 now!

Dr. Roy Spencer very sorry, but it might help?
“While stem cells show promise for heart attack treatment, the process of harvesting and reintroducing the cellswhich can take days or weeksis too slow for this window. A new study in the American Journal of PhysiologyHeart and Circulatory Physiology reports a more practical approach called microsphere therapy that can be kept on-hand and administered more readily than stem cells.
Heart attacks occur when the hearts blood vessel is blocked and blood flow stops, cutting off oxygen to the heart. Reopening the blocked blood vessel is the first step in treating the heart, but restoring blood flow is not enough to heal the heart. Oxygen deprivation damages the heart, and restarting blood flow can worsen the damage. Studies have reported that stem cells can effectively support the heart not by becoming new heart cells, but by releasing healing proteins, including ones that promote blood vessel growth.
Blood vessels are important for recovery because they give the bodys repair processes access to the damaged regions. Specific proteins can stimulate blood vessels to grow back, but using proteins directly is not effective because they degrade easily and are difficult to store. To extend the shelf life of proteins, researchers from Erasmus Medical Center in the Netherlands used a biodegradable material called PolyActive, which keeps proteins intact, protects them from degrading and steadily releases them over a period of time. In addition, proteins in PolyActive can be stored without losing their effectiveness.
For this study, the researchers combined blood vessel growth protein vascular endothelial growth factor (VEGF) with PolyActive to form microspheres and tested the microspheres effectiveness in pigs with induced heart attacks. The researchers observed that the microspheres were not toxic and stayed in the heart for at least 35 days.”

Solar wind and electric-microphysical process is the key mechanism that
affects climate
We investigated the influencing mechanism of high-energetic particle
precipitation modulated by solar wind on the Arctic Oscillation (AO) and North
Atlantic Oscillation (NAO). On a day-to-day time scale, Zhou, Tinsley, and Huang
(2014) and Huang et al. (2013) found that the minima in AO and NAO indices only
lagged 0~2 days of the solar wind speed (SWS) minima during years of high
stratospheric aerosol loading, which suggests a much faster mechanism of solar
influence on the atmospheric system compared to the ozone destruction process. From
the perspective of year-to-year variation, Xiao and Li (2016) and Zhou et al. (2016)
showed a robust relationship between SWS and NAO in boreal winter. These
aforementioned studies indicate that the wintertime Iceland Low in the North Atlantic
was very sensitive to solar wind variations and played an important role in the process
of solar wind and electric-microphysical effects on climate. Moreover, under the
condition of a weak electric field, we have demonstrated the marked impact of cloud
droplet electricity on the collision efficiency of cloud condensation nuclei. This, in
turn, suggests that the collision in a cloud microphysics process constitutes the core
link between atmospheric electricity and climate (Tinsley and Leddon 2013; Tinsley
and Zhou 2013, 2014). Furthermore, Tinsley and Zhou (2015) improved the collision
and parameterization scheme that varied with electric quantity in a cloud
microphysics process and quantitatively evaluated the effects of high-energetic
particle flux on cloud charge.
This achievement not only supports the marked association of solar activity with
weather and climate change on various time scales, but also but also avails the
quantitative accession of solar impacts on climate. It is worth noting that the
successful establishment development of a theoretical model regarding of the
influencing process of solar energetic particles on the atmosphere improves the
development of global climate models.
