LNM issues included in chart corrections

These updates include all those derived from Coast Guard Districts 1, 5, 7, 8-gulf, 9, 11, 13, 14 and 17. District 8-rivers, formerly called district 2, publishes a Local Notice to Mariners but it does not include chart corrections in the usual format. The Coast Guard also has Antilles and Marianas sections, but I have not attempted to do anything with those.

The Coast Guard started to put Local Notice to Mariners online in 1995. The first issues online in the various districts are as follows:

           First

  13       14/95
  14       17/95
  17       17/95
The following issues are missing for one reason or another. Some of the files appear to be on the server, but actually they contain different issues from the ones claimed. There are also some issues that are present but not in a format I can read.

There is an automated process which looks for new issues of LNM on the Coast Guard FTP site, brings them to my machine, and scans them for corrections to be included in these files. This process runs every night, unless my machine is down, the Coast Guard's machine is down, and so on. However, the LNM issues appear on the Coast Guard site in batches, often after a delay of a week or so.

If the automated system can process the LNM issues without human intervention, then the updates are posted immediately. If there is a problem which needs my attention to correct (which happens 5-10% of the time) then the corrections for that district are delayed from a few days to a week or so until I can attend to them.

Here are the latest issues that have been included in the corrections:
