From the “Annals of the Astrophysical Observatory of the Smithsonian Institute”, 1908:

“Mr. Langley expressed the hope that careful study of the radiation of the sun might eventually lead to the discovery of means of forecasting climatic conditions for some time in advance. It is believed that the present volume will aid materially to show how far that hope may be justified, for it contains careful and comparable measurements of the solar radiation, extending over several years. Those indicate that the sun’s radiation alters in its intensity from time to time, and that those alterations are sufficient to affect the temperature of the earth very appreciably.”

Mt. Wilson: 2008, Friday the 17th of October, 2008, 15:27 ut, Seeing 2.5, J. Boyden
No sunspots seen today.
Uccle: Image Continuum 2, no spots visible but numbered.
Royal Observatory of Belgium Drawing: No spots drawn 8:00 ut
IPS: No spots visible on Calgoora White Light Image
But we have noaa reporting sunspot # yesterday to be 24.
Yesterday was no different than today: Spots reported not visible on projections but on ccd images and Magnetograms and H-Alpha.
Are they that desperate?
Seems like it.

I have checked all the other observatories I can find, Mt. Wilson, Calgoora, Uccle and the last sunspot sighted was by Mt. Wilson on Oct. 12th. Catania I suspect is playing Hubble imager with sunspots, coming up with data that is skewing the real picture. I have watched Calgoora since this last spot 1005 appeared, and it faded off on the 12th just as Mt. Wilson last recorded it. I object to Catania polluting the pool of sunspot data just because they can. The Sept. 11th spot and one other spotted by Catania falls also under this category of CCD sunpot, and should be reviewed and the record corrected.
If Catania and other wish to further the knowledge of sunpots at minim using advanced imagers, that’s fine, but don’t do it at the expense of historical records that need to be maintained of the highest possible integrity.

nobwainer (18:16:02) :
can you explain Leif how a SC24 spot can be in the southern hemisphere
Spots from any cycle can be in both hemispheres.

is it just simply that the leading spot has a different polarity to a leading spot that might exist in the northern hemisphere right now?
Yes the two hemispheres have opposite polarities for the leading spots. Also, the high latitude is a clue.

As far as I can see, the SC23 area has now produced a sunspeck on SOHO MDI.

I’m not finding anybody’s images of sunspots except good old Catania. From looking at their image this morning, and doing a projection myself, they are imaging the Sun at very high resolution. I couldn’t pick up thos spots in a 6″ APO for crying out loud.
I call what Catania is up to image historgram stretching. That’s great if you are looking for faint galaxies to count in distant clusters, but this is ridiculous.

solarcycle24.com is reporting SC24 spot in southern hemisphere…is that correct?
Yes, and there is also a growing SC23 area near central meridian. No spot yet.

For all of you Sun Worshippers out there some very nice pictures here
Number 4 is of special interest. It shows how the facular brightening [one of parts that makes up TSI] comes about by us looking ‘sideways’ into the ‘hills’ and seeing the hotter material inside. Somewhat analogous to this: http://arfarfarf.com/photos/2006_burning_man/lava_glowing_br.php

I’m getting reports on solarcycle24.com of new sunspots in addition to 1005. But I don’t see any visible image showing 1005 any more, and nothing on the new spots by Catania.
