Group Description

Subscribers to CVnet-circular will receive a weekly CV Circular summarizing the previous month's CV activity and the observers who are supplying the coverage. The CV Circular is generated using the most up to the minute data from the AAVSO International Database.

The star name is given first, then the type of variable in parenthesis.
The following numbers are the magnitude of the variable for each of the prior 30 days (in parenthesis).
The magnitudes are calculated by averaging the observations in the AID.
The magnitudes listed are averaged from Johnson V and visual data combined, as if they are the same.
If there is no data for the date there is no circular entry.
If only upper limits (less than) observations are reported the faintest magnitude is used.
The observer codes for those submitting data on each star in the prior 30 days are listed in alphanumerical order.
A key to observer codes is included at the end of the circular.

Some uses for this Circular:

You can see at a glance what your star of interest has been doing for the last 30 days.
You can see which stars are heavily observed and which receive little attention.
You can use it to help make decisions in building your own observing program.
You can see who is observing the same stars as you, and if you wish you can communicate with them on shared interests.
You can sometimes identify discrepant or misreported data and help to sort things out with headquarters and the observers.
