Mira Predictions - 2022

Predicted Dates for Maximum and Minimum of Mira Stars on the BAAVSS programme.

Predictions are shown only to the nearest month when the star can be seen at Maximum or Minimum.  This is done simply to avoid bias!

Where two months are given, the prediction could be in the latter of one or the beginning of the other.

At present there are no BAA charts for SU Cnc, U CVn, RT CVn, RS Leo & X Lyn.  Please use the AAVSO VSP for these stars.

*=Extreme Range.  <=Fainter than.  ~= Approximately.  M-m = the fraction of the period taken in rising from Min.(m) to Max.(M).

These predictions can also be found in the BAA Handbook.
