Notes:
I was able to make an observation on the last day of the year (the new millennium starts in 2001 as we all know). I noted a very strange group of 5 small, dark (1-2/10) condensations along the northern edge of the NEB (NEB-N) which I think you will find interesting. I do not believe that these features have been previously reported (am I correct?). Please let me know what you think of this unique observation. Significant detail was noted as well throughout the disk. Would you please forward it for me to John Rogers and A.L.P.O.
