For consistent use, I'd say no. STEREO A is out in different conditions. There is even very slight differences between ACE and DSCOVR as they orbit around L1.

ive only now seen this, thank you

is this similiar to last months G4? I dont remember the data (bz wise and speed) 

Its a bummer entire Northeast of US is cloudy tonight. Wishing our european members a great show!

@Vancanneyt Sander What do you think of the conditions will reach kp9?

The last G4 was an embedded flux rope in a CH HSS, about -16nt Bz.

wasnt it more than -16 ?

Looking at the data, the lowest spike was -17.54nt I think from DSCOVR.

¿No fue más de -16?

-17 south bz when the g4 storm was on that day 24 of manzo so it can be said that this storm barely surpassed it

It's very cloudy here in the U.K. at the moment. A slight chance cloud might lift in my locality around 3 a.m. !

fingers crossed for you mike

and the bz returned to the north, well that reassures me,

The peak Dst was -163, and now we're at -170. There's also the Russell-McPherron effect near the equinoctes making geomagnetic activity more prevalent, so the fact that we're seeing more activity now despite last month's storm having occurred right after the equinox is further testament to this storm being stronger.

I did see the Bz flip just now, but it can flip back just as quickly; we'll see.

For me, it looks like clouds are going to roll in just as it gets dark… I only can hope they hold off long enough to catch a glimpse.🤞That’s if the bz is still south by then.

El pico Dst fue -163, y ahora estamos en -170. También está el  efecto Russell-McPherron cerca de los equinoccios, lo que hace que la actividad geomagnética sea más frecuente, por lo que el hecho de que estemos viendo más actividad ahora a pesar de que la tormenta del mes pasado ocurrió justo después del equinoccio es un testimonio más de que esta tormenta es más fuerte.

Vi el giro Bz hace un momento, pero puede retroceder con la misma rapidez; ya veremos.

Yes, the BZ towards the north is calm, I am at peace, it can be said that I am a hyperactive person and that when I am afraid of something I get very nervous, so as long as the BZ is in the north, calm down and I will be at peace.

what do you expect if it flips back down?

The negative Bz puts on a good show. There is no need to worry, this CME is slow compared to some others.

The sheath appears to be coming to an end, it will be interesting which orientation the magnetic field in the coming flux rope will have.

More fancy lights in the sky...that I won't see anyway.

Have you seen the drop in temperature, speed, etc?

I think that is because it has switched from DSCOVR to ACE for the moment.

A drop in temperature could indicate that we have been hit by the CME core. The core could also explain the rapid shift of the Bz.

DSCOVR having issues. ACE was down and is back up, so I'm guessing the SWPC will switch to that soon.

ah, thanks. 
So we either hit the core (isnt that a bit early?) or its the different satellite. i remember unreliable data when they switch. the BZ seems to be accurate though since the KP is lessening.

The sheath comes first and flux rope comes second. DSCOVR and ACE are slightly different, but the velocities seems to have risen to somewhere around 700km/s at this point.

Random guess of a flux rope arrival around 05:00Z, give or take a few hours
