Still no sign of Solar Cycle 24

with 7 comments

Here’s the latest trend chart from NASA. Apparently the Sun knows nothing of the predictions of NASA solar scientists regarding solar cycle 24.

Today’s pictures of the Sun show an absolutely featureless disk:

and the magnetogram shows absolutely no sign of any magnetic activity

I’ve no idea what this portends for the Earth’s climate so we’ll just have to see what happens next.

  1. Cool. When did you start this site?

  2. Give it time I suspect it’s a little early yet.

  3. I started this a few months ago. I just wanted to get a handle on the current state of solar science.

    At the moment, the late arrival of Solar Cycle 24 and the predictions of its strength seem most noteworthy.

    Any help with pertinent solar physics articles gratefully received.

  4. Glad to see you’re still writing in this blog.

    It’s astounding that we have still not seen a single Cycle 24 spot at this late date. Admittedly, that fact could change tomorrow, but it’s an interesting surprise. Surprises are learning opportunities!

  5. Still nothing on the disk. According to solarcycle24.com, that makes 15 straight days so far.

    I was rather skeptical about Archibald’s claims as to the late arrival of Solar Cycle 24, but the longer this goes on, the more likely that the next cycle will be weak rather than strong.

    I suppose that the main question is what effect this will have on the Earth’s climate and in particular its cloudiness from Svensmark’s hypothesis. We enter some interesting times…

  6. Link to “Spotless Days” page,

    http://users.telenet.be/j.janssens/Spotless/Spotless.html

    with records of periods of spotless days => 20 days since 1849
