We have updated the spreadsheets listing known variable stars with companions.

When you make charts for new variables, always check the notes in the chart regarding the presence of close companions so you can be prepared and perform your photometry acordingly.

In this update, there are some interesting stars, like CE Lyrae. This one has a 13.4 mag. companion only 5.3" away and all the observations (visual and V) are for the blend of the two stars.
See this phase plot based on AAVSO data.

Is anyone able to split the two and follow CE Lyr when it goes down to <16 V?

Another interesting case is V0759 Oph. This time the companion is unresolved so you can't do anything about it but it is amazing to see how something we can't see can be detected indirectly by looking at the star's light curve.
This is the ASAS-3 light curve of this object.

The new objects are shown in blue cells in the new spreadsheet.
