[BAA Comets] George Alcock Memorial Lecture + new comets discovered from Brazil and Australia

[Richard Miles]

Thanks for doing this, Nick.

I see that since my talk last night, two new comet discoveries by amateurs 
have been announced !

First is a periodic comet. P/2017 K3, orbital period 12.8 yr, by Goran 
Gasparovic based in Croatia but he was using a 0.5-m scope at iTelescope 
Siding Spring, Australia.

Second is by Cristovao Jacques namely C/2017 K6 (Jacques) using the SONEAR 
facility at Oliveira, Brazil. That makes 3 comets with his name on in the 
last 3 years. The same 0.45-m f/2.9 telescope has now been used to make a 
total of 5 comet discoveries in less than 4 years. One of Cristovao's 
earlier successes was using a 0.28-m f/2.2 reflector.

Congratulations to both observers. The total for last year (2016) was just 1 
comet by any amateur (namely C/2016 R3 (Borisov)).
So far this year we have had 6 amateur discoveries announced and we are not 
yet halfway through the year.

Richard
