Can anyone tell me (or point me in the right direction to find) when Mira is next at maximum brightness? Google has let me down badly and I can't find a straight answer.
Read the instructions on how to use the bulletin. Unfortunately the latest bulletin covers to the end of 2005 only. You could add 332 days to the last maximum.
Here is an article about Mira which has maxima predictions but, again, stops at April 2005!
