Tomeasure these basic quantities, we conduct a deep narrowband imagingsurvey in four different fields, Chandra Deep Field South (CDFS),Chandra Deep Field North (CDFN), and two COSMOS subfields, for a totalsurvey area of 1.2 deg&lt;sup&gt;2&lt;/sup&gt;. We discover 25 blobs at z = 2.3 withLyα luminosities of L &lt;sub&gt;Lyα&lt;/sub&gt;= (0.7-8) ×10&lt;sup&gt;43&lt;/sup&gt; erg s&lt;sup&gt;-1&lt;/sup&gt; and isophotal areas of A&lt;sub&gt;iso&lt;/sub&gt; = 10-60 sq arcsec. The transition from compact Lyαemitters (LAEs; A &lt;sub&gt;iso&lt;/sub&gt; ~ a few sq arcsec) to extendedLyα blobs (A &lt;sub&gt;iso&lt;/sub&gt; &amp;gt; 10 sq arcsec) is continuous,suggesting a single family perhaps governed by similar emissionmechanisms. Surprisingly, most blobs (16/25) are in one survey field,the CDFS. The six brightest, largest blobs with L &lt;sub&gt;Lyα&lt;/sub&gt;gsim 1.5×10&lt;sup&gt;43&lt;/sup&gt; erg s&lt;sup&gt;-1&lt;/sup&gt; and A &lt;sub&gt;iso&lt;/sub&gt;&amp;gt; 16 sq arcsec lie only in the CDFS. These large, bright blobs have a&lt;/p&gt;
