Skip to comments.Mars-sized 'Light-bridge' on Surface of Sun Appears to Signal Break-up of Vast Sunspot

Amateur astronomer and Florida resident Howard Eskildsen snapped an image of the "light bridge"which has a length that's roughly equal to the diameter of Marsin a recently formed sunspot dubbed AR2770, spaceweather.com reported.
These phenomena are caused by strong magnetic field concentrations, which inhibit convectionthe transfer of heat from one place to another within gases and liquids. This process heats the solar surface.
Hot "bubbles" of plasmacharged particles that are one of the four fundamental states of matterare transported from deeper, hotter layers to the surface, whereas cooler plasma is transported back to the interior...
According to Felipe, light bridges are bright, elongated structures that are commonly present in sunspots, which connect regions across the cooler, darker abyss of the sunspot.
They are created by the intrusion of plasma where the magnetic fields are weak into the strongly magnetized sunspot. In the light bridges, convection can still take place, which is why they are hotter than the rest of the sunspot and, thus, look brighter.
While there is still much we don't know about light bridges, they usually herald the break-up of the sunspot in question.
Currently there is not much activity on the sun and AR2770 is one of the most interesting features on our star at this time, according to Felipe. In fact, AR2770 is one of the first sunspots from the next 11 year solar cycle that scientists think is starting around now.

Now it's only half vast.
Thank you. I'll be here all week.
Let me go on the record:
I’m in favor of more Sun-Spots.
“Appears.” Please inform us when and if this happens. I will be looking forward to a final synopsis of the “appearance.” I will not hold my breath. Thank you.
If you live somewhere where the winters are harsh you’d best be chopping and stacking firewood for the next couple of months.
Well, the two “compounds” I’ve owned are located in flora mature neighborhoods.
>42 years of cutting growth out.
Unfortunately I’m counting on natural gas to continue to flow from places in the northern Rockies and places a bit to the east [ND].
I’m 87 and spend a lot of time just sitting in my garden for years but this year I have had my ears sunburned 4 times with peeling in between...
“In fact, AR2770 is one of the first sunspots from the next 11 year solar cycle that scientists think is starting around now.”
Is this a reverse polarity sunspot?
Are we entering a sun polarity that is the same or opposite that of earth?
Me too. I need better radio propagation.
Is this going to lead to mass corona ejaculation?
O dear God
Charge of the light bridge-gade.
You should wear a hat when sitting outside.
