Failed to parse TLE message

While running auto-scheduler I got quite a few messages like the following:

2019-10-14 16:35:07,536 - root - INFO - Fetch from

2019-10-14 16:35:08,785 - root - WARNING - Failed to parse TLE for LO-19

The problem occurs with a couple dozen satellites, meanwhile other satellites TLE seems to be recovered well.

Any idea?

This tle source is corrupted since a few days. I have commented (erased) out the nasabare line from the sources.csv file to keep running.

However, I think it is now fixed so it may be useful to clean the cache in /tmp/cache/tle*.

Indeed, the TLEs are malformed. Some negative numbers have been replaced by ‘n’ for some satellites. For now the auto-scheduler will skip those. If they’re important you can schedule them manually, but also check if the TLEs are fixed. @pierros has informed AMSAT of the issue.

Apparently AMSAT is aware of the issue and are looking on ways to fix it.
