I don't know why, but as you can see in Steve's plot from earlier this morning, the PMC transmission has been going down significantly all weekend. The PMC refl camera was very bright. I tweaked up the alignment (mostly pitch), and now we're back to normal.
The IMC was having trouble staying locked all morning, and I'm hoping that this PMC adjustment will help - the MC already looks better, although it's only been a few minutes. |
