Nothing wrong with your sun clock. You linked to a 'live' URL, so it will slowly become less salient, then meaningless with respect to the current discussion.
Better to save the image with a screen-capture tool and attach, in order to 'stop the clock'.
Hope that helps.

But we don't really need to be flooded with Vuk's plots. we can go ourselves to the site to get what we want. |

Now we are cooking with gas! SFI at 125! Go baby!

The solar wind takes 3-4 days to get here, so the changes are not related. As I said: it looks like an instrument malfunction to me. |

Has this kind of instrument malfunction occurred in the past?
And what's you're thoughts on the solar wind speed readings that also reacted in sync with this rise to a 'static state' in the Bt field.

Oops, CME. Sorry, I thought you were commenting on the SFI rise.

And what's you're thoughts on the solar wind speed readings that also reacted in sync with this rise to a 'static state' in the Bt field. yes [if memory serves]. Now, the field has been constant for 10 hours. This is definitely instrumental. Normally the density follows the field, as you can see here: hirweb.nict.go.jp/sedoss/solact3 [density green, field orange]. But there is no abrupt change in density when the field jumps to its high constant value. This is based on past typical behavior of the solar wind. It is, of course, possible that the jump is real, in which case we learn something new.: that the solar wind CAN have such strange behavior. What changed my mind was the latest data from the WIND spacecraft: pwg.gsfc.nasa.gov/windnrt/ |

Now we are cooking with gas! SFI at 125! Go baby! Paul the 304A index is much lower right now than last fall when the SFI was struggling to break 90. Unfortunately HF MUF is behaving more in line with the 304A numbers than the SFI. ;D |

@leif > ... as you can see here: hirweb.nict.go.jp/sedoss/solact3 ... That is a very informative and useful chart, fusing a month's worth of information from sunspots, flares, solar wind and geomagnetic storms! |

Unfortunately HF MUF is behaving more in line with the 304A numbers than the SFI. ;D Thanks Bob. Went back and looked and you are correct. Another thing I noticed. Looks like the 304A caught the flare perfectly, yet the 366A did not budge. 171A and 257A also responded accordingly. Given its spectral line, I had assumed 366A would be a good indicator for flares. As it does not seem to be adding to anything, I am going to remove it from the solargraph plot to reduce clutter. I will leave yours alone for now. |

The GONG Farside Page has an interesting callout. Both the GONG and SDO HMI Seismic Images are now posted on that page.
Both are showing a very strong hit in the Northern Hemisphere at 180 degrees.
GONG treats it as a returning area.
SDO HMI has it labelled as a new area with a 100% chance to emerge.
Raben Maps and STEREO's Homepage show old 1153 at about 170 to 175 degrees and the same Lattitude.
This ought to be interesting !
