NOTE: Please provide your own carriage returns when entering text into the "Description" area! Otherwise, your submission to IAAC may come through with a single long line of text for this field!

NOTE: If you frequently observe from the same site and/or with the same equipment, try building your own custom observing form with the "IAAC Personalized Observing Log"!

If you have any questions or comments about this Web form or about the netastrocatalog mailing list, please contact the list-administrator. If you have more general questions or comments about DEEP-SKY OBSERVING, post a message to the IAAC discussion list. You may also browse the Web archive for all previous logs, or search the archive for a particular object. Or return to the Internet Amateur Astronomy Catalog home page!

Also, please feel free to use your own yardsticks for seeing and sky darkness: using the seeing scale of I-V, sky "transparency" scales of 1-5 or 0-10, sky brightness in magnitudes/arcsec^2, or John Bortle's excellent transparency scale from 1-9 etc. are all just as "valid" as our 1-10 seeing and visual limiting magnitude. Just be sure to note which one you're using!
