Announcement: New Applications
We are excited to announce the launch of our new applications! We're opening up early access to our new applications for searching, downloading, and submitting photometric observations. You can now access these applications through these links:
We ask for your feedback in order to help us improve these applications. Please send feedback for the applications above to feedback@aavso.org. Note: please avoid duplicating submissions across the two submit applications.
The short answer is "No!" - it is not valuable to sepnd your effort monitoring tnem. The longer answer is that there are numerous photometric surveys that record such stars as "by-catch", so they won't actually be lost if they aren't truly constant - but the likelihood - very high, normally - is that they are actually constant and were mis-classified for some obscure historical reason.
Ok, Thanks! The reason this came up is I was perusing the Sky Atlas 2000 and noticed quite a few "variables" plotted besides the ones I am familiar with. Upon looking them up, a significant number of them were CST. I even looked at some light curves, but just saw random scatter.

What does CST stand for?

"constant":
CST
Non-variable stars (constant), formerly suspected to be variable and hastily designated. Further observations have not confirmed their variability.
oh good to read your posts as i was planing to observe this star but then this is a constant so no need really. thanks
