Subscribers who wish to make address changes, category changes, etc., are requested to inform us of said changes by Feb. 29. We regret that a charge of S50.00 must be made for address changes and deletions (but not additions) outside these biannual seasons. Notice is hereby given that, effective Mar. 1, the charges for telegram subscriptions by TWX/telex and by mailgram in North America will be increased from S3.00 to S4.00 and from S2.00 to S3.00, respectively, per message: charges for WU telegrams and for service outside North America will remain unchanged. In accordance with the notice on IAUC 3807, the Bureau is now pleased to announce the availability of a 'dial-in' service. Arrangements have been made with the Smithsonian Astrophysical Observatory's Computer Center for subscribers to these Circulars who have computer modems to use them both to receive and to give relevant information. The service includes facilities for the caller to read the latest Circulars, as well as to obtain orbital elements and ephemerides of selected comets and minor planets. Brief messages can be left, and it is also possible for the caller to 'upload' a prepared file of observations. At least initially, the service will be substantially less expensive than indicated on IAUC 3807: for a trial period the service will cost 30c per day (for a minimum of 30 consecutive days). For further information, contact the Bureau at the postal address or TWX number given above. 1984 January 12 (3908) Brian G. Marsden
