I have just created a comparison star sequence for TU Crt, currently undergoing a possible superoutburst. The sequence can be obtained from: http://ftp.nofs.navy.mil/pub/outgoing/aah/sequence/sumner Unfortunately this is a very sparce field, and there are no comparison stars in this sequence in the range 11 to 14. This is unfortunate, and may be able to be corrected at a later date. Thanks to Arne Henden for obtaining the original field photometry from which this sequence is derived, and also for the space on his server for this and the other sequences to be stored. If you have any comments on this sequence, or any of the others in the above directory, I would love to hear from you. Bruce Sumner
