	<abstract content_type="html">Since the very beginning of the space venture, discrepancies between
hydrodynamic models and observations have raised the attention to the kinetic
effects taking place in the interplanetary medium. After discussing some of
these constraints, a review on the state of the art knowledge on the waves in
the range &lt;i&gt;f&lt;sub&gt;ci&lt;/sub&gt;&amp;lt;f&amp;lt;f&lt;sub&gt;pe&lt;/sub&gt;&lt;/i&gt; (&lt;i&gt;f&lt;sub&gt;ci&lt;/sub&gt;&lt;/i&gt; â€“ about 10&lt;sup&gt;&amp;minus;1&lt;/sup&gt; Hz â€“ is
the ion cyclotron frequency, and &lt;i&gt;f&lt;sub&gt;pe&lt;/sub&gt;&lt;/i&gt; â€“ a few 10 kHz â€“ the electron
plasma frequency) observed in the free solar wind, i.e., not magnetically
connected to the Earth&apos;s bow shock, is addressed.</abstract>
