We found that we were using old flats since SRO started up this Fall, so we're in the process of reprocessing images from 2014-10-11 until current.  You may get a few "you've got data" messages.  You might try a couple of randowm fields to see if the new flats make any difference in your photometry (our guess is that you won't see much change, and the processing can be ignored).

BSM_HQ is getting a new set of filters for testing, compliments of Chroma Technology.  These are colored glass filters, cheaper than the dielectric filters.  We will be testing these for a couple of weeks using the old ST-7 camera.  The ST-8 has been repaired and will be installed after the filter testing.

BSM_NM has a new ST-10XME camera and 10-position filter wheel.  The available filters are BVRI, griz, Halpha and a diffraction grating.  We've also done a few other changes, so it may take a few days for this system to become stable.

OC61 is offline for about another week.  The Robofocus controller has failed, and we are getting a new one shipped to Mt. John.

Everything else is working the same as from last month.
