Percy's paper on the role of visual observations

Due to the New England winter storm currently affecting the area, phone coverage at the AAVSO may be much reduced until Wednesday. The staff is still available via email, and we suggest using that method to contact us if you need assistance.

A must-read.
If you are still wondering if visual observations are needed in the 21th Century, the answer is yes.

There are CV outbursts to catch, new SNe to discover, more long-term trends to be found, more eclipses to be caught.

For those who dare to deal with small amplitude stuff, Be-star outbursts (GCAS) are also interesting. Let me give you an example:

Mu Centauri in outburst, detected visually. Last week the star had faded from its first peak but my skies have been clouded by more than a week so I don't know if it has re-brightened or not.

Cheers,
Sebastian
