It has been pleasing to see that this challenge has generated interest, both in debate and in observations. This was always the intention and I have also learned things I was not aware of astronomically which, as mentioned, is why I’m a member etc.
The challenge was not meant as a UK based challenge and that is not inferred anywhere in my piece. So it is doubly pleasing that observations are coming in from well outside the UK.
There are always differences of opinion, both here and on other fora. The level of expertise also varies enormously but that is to be expected and not, in my opinion, something to use as a criticism of other internet fora. The more useful tack would be to correct errors and impart knowledge when it is apparent that someone doesn‘t understand something. Of course, the manner in which this is done is important.
