The cloud free DNB images from January to February 2014 were all processed. We use two
examples on Figure 1 (1524 UTC on 23 January 2014) and Figure 2 (1647 UTC on 25 February
2014) to show how DNB image performance. From the results, we could very clearly to know
the location of vessel light from Neon flying squid fishing operations. The green marks are the
reported fishing location from Hachinohe vessels. Although these reported data do not match the
