Since the start of the campaign on 19th June we have had over 15000 photometric observations logged to the AAVSO database for our three target stars from volunteer astronomers all around the world. Access to the AAVSO database of photometric observations is freely available to anyone online and light curves can be generated using the AAVSO light curve generator. An example of the excellent work carried out by some of the observers is given below, with a light curve of Ross 1154 captured on the night of 12th July showing a large flare.

So who are these intrepid observers? What motivates them? And how do they carry out their work? We decided to ask some of them to find out.
I first spoke to the Belgian astronomer Franz-Josef (Josch) Hambsch.

Can you give any details of your observatory and the equipment you use?
I have a remote observatory in the Atacama ...
