Rads on a Plane! Holes in the Sun! Flares!

Not for Rad Trads, unless you are also frequent flyers…

From Spaceweather

RADS ON A PLANE: Regular readers know that Spaceweather.com and the students of Earth to Sky Calculus regularly fly balloons to the stratosphere to measure cosmic rays. For the past six months, May through Oct. 2015, they have been taking their radiation sensors onboard commercial airplanes, too. The chart below summarizes their measurements on 18 different airplanes flying back and forth across the continental United States.

CHANCE OF FLARES: NOAA forecasters have boosted the odds of an M-classsolar flare today to 30%. They are responding to the emergence of sunspot AR2434 near the sun’s southeastern limb. Earlier this week while AR2434 was on the farside of the sun, it hurled several clouds of plasma over the limb: movie. This suggests it is capable of significant explosions.

Significant explosions.  That’s what we want to hear.

Then…

ENORMOUS CORONAL HOLE: A gigantic hole in the sun’s atmosphere has opened up and a broad stream of solar wind is flowing out of it. This is called a “coronal hole.” It is the deep blue-colored region in this extreme UV image from NASA’s Solar Dynamics Observatory:

Coronal holes are places in the sun’s atmosphere where the magnetic field unfurls and allows solar wind to escape. In the image above, the sun’s magnetic field is traced by white curving lines. Outside the coronal hole, those magnetic fields curve back on themselves, trapping solar wind inside their loops. Inside the coronal hole, no such trapping occurs. Solar wind plasma is free to fly away as indicated by the white arrows.

For much of the next week, Earth’s environment in space will be dominated by winds flowing from this broad hole. This should activate some beautiful Arctic auroras. NOAA forecasters estimate a 65% of polar geomagnetic storms today as Earth moves deeper into the solar wind stream. Aurora alerts: text or voice

I think this means that the ham radio bands may stink for the time being.

    Cool that it’s shaped like a whale! –or am I the only one? (tail at the bottom).

    Unfortunately, correcta-mundo, Padre.

    Yeah, I didn’t even bother getting the radio out last weekend.

    I say: you know the bands are bad when you have to pump 1KW into a NVIS dipole to be heard in a local morning net on 7.222MHz at 8:30 in the morning. And even that only merits an S7-8 from 25 miles away. Atmosphere must just suck up the RF like an Aston Martin drinks petrol in one big gulp.

    OMGosh! Where am I going to get the money for the carbon credits for a hole THIS big?

    Where is Al Gore? Did he see this yet? I am sure he will be holding committee meetings soon to find out which country is the most responsible for this global wa..whatever- caused event.
