Maintaining my membership of the BAA is one way that I have of continually learning about this fascinating hobby. If you were able to elucidate further on your previous reply regarding the orbit etc then I and others may further learn about Sirius and it’s Pup. In this way this debate is achieving its purpose. Your reply certainly indicates that you are able to do so. In fact I am confident that you can as, of course, I am aware of who you are and your expertise in many astronomical matters.
Please note that this is designated as an Observer’s Challenge. The challenge is to try and observe the Pup, should anyone decide to try and do so. There is no compulsion. In this respect it seems that it is possibe to do so, witness images and other replies earlier in this thread. The use of the word ‘challenge’, also indicates that it is not meant to be easy.
