Use the form below to prepare a list of NEAs suitable for observation according to user-specified criteria that are to be selected from the options below.
For beta-testers: documentation is not yet ready. The only "tricky" part of data entry is that the R.A. limits may be entered as absolute values (e.g., "18 30" or "18.5" to indicate 18h 30m) or as offset values (e.g., "-120" to indicate -120 degrees from opposition or "+60.5" to indicate +60.5 from opposition). There will be a PDF document available at some point in the near future...
