Mr. Lucas,

I've been doing SNe hunting for about six months using a fully
automated  30cm (12 inch) Meade LX200 with a KAF-1600 based CCD 
being controlled by a self written program.  The equipment will 
produce about 200 images per  night.  With flat and dark frames, 
that is about 175 megabytes  of data per run.  I'd like to 
solicit the comments of the more experienced observers about 
how long these images should be kept. I'm accumulating a 
reference images for each of the galaxies in my observing list. 
Obviously,  these reference images should be kept indefinitely.  
I've been deleting image files that are more than six weeks old.
I get many  images that are defective in some way because of
clouds, wind vibrations, etc.

I am interested in your opinions and experience,
Jim Waller
