Dr. Svalgaard: Is that satellite still in storage that could provide more useful information in regards to what is happening on the Sun? I don't know which one you are thinking of. Our greatest hope was the Glory satellite that was lost during launch en.wikipedia.org/wiki/Glory_(satellite) |

Dr. Svalgaard: Can another Glory satellite be produced?

Our greatest hope was the Glory satellite that was lost during launch en.wikipedia.org/wiki/Glory_(satellite)I was probably thinking of Glory. But for some reason, I seem to remember another satellite waiting for a launch date. Must be getting old. |

Any chance we could get any useful information from one the mini- to micro-satellites? Could they handle wavelength output?
Canada is doing a bunch of the mini-sats.

Hi Leif I found something may or may not be significant. Check this out. Go to the Red Trace on the 4th Panel from the top The Panel entitled...... Latest 14 days of SEM ch2, ch4 data ending.... umtof.umd.edu/sem/This is the 304A uv trace from SOHO for the last 2 weeks Now go to the top panel of. www.usc.edu/dept/space_science/OLD_WEB/semdata.htmThis is the historical values for Cycle 23 Notice that the value of the peak of the current cycle. The Photon Count is slightly above 30. Now check out the peak values in 1999. They appear to be nearly the same. What is different is the values at the low portion of the 27 Day Cycle. In the second half of 1999 the photon count never dropped below 20 where as on March 27 th as well as for most 27 Day Roatation Minimums the photon count is down to 7. A resting count at Solar Minimum is 5 to 6. This scale is log. Would this validate the theory of "Blind Spots" ? |

The plots are hard to compare as they pertain to different wavelength bands (1-500A and 260-340A) and have different units (counts minus a background and photons) so you cannot just compare the numbers. I have not gone to the trouble (if it is even possible) to make put the numbers on the same scale, so can't really comments on your question.

Leif the 1-500A is the ch2 trace which are in Blue.....Ignore them The 304A measurements are ch4 traces which are in Red. Look at the top of the SEM page for the description and then go to the historical page. One says 260A to 340A the other says 304A +/- 40A. They are saying the same thing stated in two different ways. The quantity measured on the Y Axis is photons/cm 2/second for both graphs. On the historical chart it's a linear scale. On the sem page it's a log scale. On the X axis they are measuring time. On the historical page they measure in years. On the sem page the units vary depending on which panel you are look at. The bottom panel shows a 14 day span. These are the same graph of the same quantity from the same instrument with different scales. The people at USC made this unnecessarily complicated. It took me a cou year to figure out what they were doing. I've been trying to get a hold of Darryl Judge or his staff for the last two years. The fire is pretty much out but I would like to know if they are archiving the data they receive during Cycle 24. |

The fire is pretty much out but I would like to know if they are archiving the data they receive during Cycle 24. One one Figure for ch4 it says 'counts/sec' on the other one 'billions of photons per cm2 per sec'. That looks like very different units to me. |

Perhaps if one hunts around on the websites one may find comparable data. Let me try that.

Dr. Svalgaard:
Are you satisfied with the current satellites as far as providing basic facts?
Or would you like another one launched that can do more?

Perhaps if one hunts around on the websites one may find comparable data. Let me try that. Here is the SEM-EUV run simce 1995:  The red and blue curves are the observed fluxes. The purple and green curves are calculated from a fit to the SSN over then interval 1996-2008 (cycle 23). For cycle 24 the observed values fall significantly below what we would expect for the SSNs observed. My inclination would be to interpret that as progressive degradation of the instrument. This is bolstered by this plot of the ratio between the observed and calculated fluxes:  |
