Nights are moderately long (though dusty and/or smoky) in these parts.

The orbital period of 0.18864 days according to AAVSO appears well determined.  What is the value of further lengthy observation runs?  Is there a suggestion that the period may be changing or are we looking for flickering in the accretion disk?

I am prepared to spend some telescope time if it is worth my while but there other calls on it too.

(Added in edit: not that it makes any difference tonight. Complete cloud cover as of about 45 minutes ago.)
