| MGL0910_16 shot with gun strings 1-4. String 1 remains a problem. During the early morning local time gun string 1 continues to deteriorate. This string is causing no end of problems.
While moving gun string 2 out of the way, it becomes entangled with gun string 3. Almost all of MGL0910_23 is shot with only two gun strings (3 and 4). Gun string 1 is not working; gun string 2 is entangled.
At the end of MGL0910_23 gun strings 2 & 3 are disentangled. For most of MGL0910_20 the Langseth array comprises gun strings 2, 3 and 4 and part of gun string 1.
After completion of MGL0910_20 gun strings 1 and 2 are recovered and swapped. The purpose here is to get the problematic gun string 1 into the 2 position so that it is easier to work on this string. We are hoping that in this new configuration gun strings 1, 3 and 4 will be relatively stable and that with the problematic gun string 1 hardware in the 2 position we will be able to do maintenance on while underway. It is anticipated that for this inner volume the availability of 75% of the array may be sufficient. Only time will tell; it is a risk.
