Topic: Astronomy Page Sun Spot image

[andro700]

For some reason my sunspot image is not showing up. Here is a link to my page. I am not sure who wrote the script though.

It's not directly your problem.  It has to do with NASA no longer using that image as a link.

[gwwilk]

My image is found here in 'include-wxastronomy.php':

Code: [Select]

// SUN: images available from: NASA Goddard Space Flight Center (128x128)      .
   $sunURL  = 'http://umbra.nascom.nasa.gov/images/';
and my Sun Image is

Code: [Select]

  // pick your sun image from one of the above choices
   $sunImg = $sunK128;
The choices I have in 'include-wxastronomy.php' are:

Code: [Select]

  $sunA128 = array('latest_aia_171_tn.gif',
     'http://umbra.nascom.nasa.gov/images/latest_aia_171.gif');   // Fe IX, X 171 Å (blue   ... sun spots and flares)
   $sunB128 = array('latest_aia_193_tn.gif',
     'http://umbra.nascom.nasa.gov/images/latest_aia_193.gif');   // Fe XII 193 Å   (green  ... sun spots and flares)
   $sunC128 = array('latest_aia_211_tn.gif',
     'http://umbra.nascom.nasa.gov/images/latest_aia_211.gif');   // Fe XV 211 Å    (yellow ... sun spots and flares)
   $sunD128 = array('latest_aia_304_tn.gif',
     'http://umbra.nascom.nasa.gov/images/latest_aia_304.gif');   // He II 304 Å    (orange ... sun spots and flares)
   $sunE128 = array('latest_xrt_tn.gif',
     'http://umbra.nascom.nasa.gov/images/latest_xrt.gif');              // Soft X-ray image in the titanium-polyimide
   $sunF128 = array('latest_solisMG_thumbnail.gif',
     'http://umbra.nascom.nasa.gov/images/latest_solisMG.gif');   // Photospheric longitudinal magnetograms (gray  )
   $sunG128 = array('latest_solisHe_thumbnail.gif',
     'http://umbra.nascom.nasa.gov/images/latest_solisHe.gif');   // He I 10830 Å spectroheliograms         (orange)
   $sunH128 = array('latest_solisCh_thumbnail.gif',
     'http://umbra.nascom.nasa.gov/images/latest_solisCh.gif');   // Ca II 8542 Å longitudinal magnetograms (red   )
   $sunI128 = array('latest_K_line_thumbnail.gif',
     'http://umbra.nascom.nasa.gov/images/latest_K_line.gif');    // RISE/PSPT Ca II K filtergrams          (blue  )
   $sunJ128 = array('latest_mk4_thumbnail.gif',
     'http://umbra.nascom.nasa.gov/images/latest_mk4.gif');       // White-light Mk. 4 coronameter          (halo  )
   $sunK128 = array('latest_hmi_igram_tn.gif',
     'http://umbra.nascom.nasa.gov/images/latest_hmi_igram.gif'); // Helioseismic and Magnetic Imager (HMI) (orange ... smooth)
but I won't guarantee the validity of all of the links, just the one I'm using.

Still not working. I will look at it more in the next couple of days. Felt like crap all day did not work on it to much.

Spaceweather-dot-com has a nice one that's updated frequently if you want to try a different one.
Hope you're feeling better soon.

Spaceweather-dot-com has a nice one that's updated frequently if you want to try a different one.

Nice image.  Is there a thumbnail, Dan?  Loading such a large image just to squeeze it down to thumbnail size seems wasteful of time and bandwidth.  As now, the large image could then be linked to the thumbnail.

Nevermind...I found the thumbnail on their site.  These image urls are coded with the date, so to obtain the most recent one would require coding the date information into the url.  I'll think about doing this just for kicks.

Here is code that displays the Spaceweather.com sunspot image.  In 'include-wxastronomy.php' substitute this section (shown in context):

Code: [Select]

date_default_timezone_set($SITE['tz']); # Reset 'tz' to default
$yr4 = substr($yrmoday,0,4);
$yr2 = substr($yr4,2,2);
$mo = strtolower(substr($yrmoday,4,3));
$today = substr($yrmoday,7,2);
// End Spaceweather.com calculations

              title="<?php echo langtransstr('Click for Larger Sun Spots Image'); ?>"/></a><br />
      </td>
      <!-- EARTH IMAGE -->
I've added a link to the Spaceweather.com site in the 'Sun Spots' title over the thumbnail.
(My apologies for the formatting--I use tab2, and it gets messy here.)

Got it working! Thanks for the assistance gwwilk, very much appreciated.
