Of course it happens while im skiing. And while I am (like now 😂)

I cant even go skiing. We have really stormy weather here in Austria and +10°C ☹️

Lucky too warm here

You can thank stereo b for that not being a thing

but than we also could not see the far side... Stereo Behind would be on L2, We need one farther out than STEREO A, like on L3 or something like that

It started spinning for some reason/ some sort of glitch and the antennas couldn’t communicate with earth

So it’s gone

Dang..

But what exactly is the difference between STEREO A and STEREO B? Aren't they the same thing?

Exactly the same thing, only on different positions. one is right, one is left.

Stereo A (Ahead) sees the Sun, before it is facing us.

Stereo B (behind) sees the Sun after we did, thus making it able to see what regions are up to once they rotate off the limb.

For some reason though in 2014 there was full disk images combining stereo a and b

That could see the entire sun

STEREO A is closer to the Sun than Earth making it have a shorter orbit while STEREO B is further away having a longer orbit. In 2023 after about 17 years both satellites and Earth will be nearly aligned and the closest together since the STEREO satellites were launched in 2006.

We really really need new solar observation probes on all sides of the Sun. 

We do.  I find it shocking that we have no significant solar observatory missions coming or even proposed. Nothing.

ESA has two or three probes coming that will fly eccentric orbits around the sun hoping to catch glimpses of the polar regions that we know little about.  The Russians have two probes coming along intended to leave the solar system at a high enough speed to take measurements of the interstellar medium from up to 85 AU by the middle of the century.

But as far as steady observation of the sun like STEREO, there's nothing even planned.

Voy a ser honesto... no lo entendí en el último tweet  😅 (tal vez podría ser el primer idioma es español y soy un aficionado en esta área)

hola solo dijo que uso la palabra "amenaza" por el filamento solar, pero nada mas  eso dijo en el twitter ese (wave only said that he used the word "threat" because of the solar filament, but that's all he said on twitter)

I dont want to lose hope that someday, somehow, Stereo B will be revived.

No. I dont want to take your hope but i quote: "Four years after the initial loss of communications anomaly with STEREO Behind observatory, NASA has directed to cease periodic recovery operations with the last support on October 17, 2018." 

2016 they could periodicly communicate with STEREO B, but the Battery State was very very low and because of the Spin it could not be stabilised, so the solar panels also couldnt charge the battery

Quote: "Communications with Solar Terrestrial Relations Observatory-B (STEREO-B) were lost on Oct. 1, 2014, due to multiple hardware anomalies affecting control of the spacecraft orientation. Communications with STEREO-B were re-established on Aug. 21, 2016, during a monthly attempt to reach the spacecraft using NASA's Deep Space Network. During the next weeks, the NASA and the Johns Hopkins APL STEREO teams worked tirelessly to discover the spacecraft's current conditions and to recover the spacecraft fully. The attempt to recover the spacecraft was not successful. STEREO-B has now been out of contact since Sept. 23, 2016. 

Well, they now dont even try to re-establish the contact, even if they could (and they can) track STEREO B with the DSN (DeepSpace Network)

😔

These 2 Sunspots appear very "indented" on the HMI Dopplergram... 

The umbra is a colder region and thus tends to be a bit “deeper” than the solar surface. That’s also why it’s not possible to determine the magnetic layout of sunspot regions that are so close to the limb.

Ohhhhh thanks, i didnt know that! Well, learned something new 😁

Does this say anything or what is tahat dopplergram for?

Is AR2936 or AR2954 to be correct a dud?

well yes, but also no. 

I dont know what may be still behind the limb aaaaand we dont know if it developes more Sunspots. Now we have to play the waiting/patience game. Just wait, and see.

The region might have connected to you with telekinesis and heard you talking about it shrinking...🤪😅

look, it wouldnt do that, or would it?

well ok then.

HOW do we know? Because i dont know how it can be said that a specific region is that region of the past rotation...
