Congrats to Dave Grennan on his SN discovery.

Dave as my post said:

I used to put C for no filter but now you just leave out the letter for no filter.

Glad your skyward observational skills are better than your reading skills.

Actually Kieran, I did read your post. If you leave out the reference filter for your magnitude estimate, then it is not used in the calculation of the H and G parameters even though it will appear in the observations. This is of course the main reason you would submit a mag estimate. Are you on the MPML? It's all on there.

I am on MPML but its linked to my old yahoo address which was spam central so I tended to just delete nearly everything. I find MPML a bit of a pain since you have to check it too often and sift the wheat from the chaff. Why don't they just but a latest news link/update on the MPC site?

Congrats and very well done Dave. Many of my friends have been asking me what this discovery is and how was it done. I have just seen what I consider to be the best coverage and explantion so far. It is by Mark Keenan of the Sunday Times (it is in the 'Home' supplement -- P12/13) with some great pictures. I suppose we are all at different levels in Astronomy and something like this would inspire you to push on to another level.
I can't wait for the next golf game so I can say to the lads 'there you go .... that's how it is done'.

Here's another good article that paints the bigger picture:

Congratulations Dave!
It must be a wonderful feeling!
