title: Python Pandas Timeseries How to find the largest sequence where the values is higher than a specific value
body: <p>How do I find the largest sequence in a timeseries.
  For example I have a <code>DataFrame</code> like this:</p>
  
  <pre><code>index      Value 
  1-1-2012   10
  1-2-2012   14
  1-3-2012   15
  1-4-2012   8
  1-5-2012   7
  1-6-2012   16
  1-7-2012   17
  1-8-2012   18
  </code></pre>
  
  <p>Now I want to get the longest sequence:
  Here it would be the sequence from <code>1-6-2012</code> until <code>1-8-2012</code> with 3 entries.</p>
  
  <p>Thanks
  Anja</p>
