We offer free conference advertising for our users, on subjects directly relevant to the scientific interests of The Astronomer's Telegram. Requests for this service should be made by a member of the local scientific committee, to Robert Rutledge (rrutledge@astronomerstelegram.org).

The request should include:

• the advertisement, consisting of a graphic (in JPG, PNG, or GIF format), which must be within 180x140 pixels (width by height). The graphic must include:
  1. Conference title.
  2. Conference start and end date
  3. Conference city
• A working URL linking to conference information
• Requested start and end date for the advertising.
• Optionally, the start dates (Monday) for up to 2 "exclusive weeks"; these are weeks where only your conference will be adverised. Possible choices might include the week that abstracts are due, and the week that registration closes.

Advertisement requests may be made at any time. Display of advertisements is currently made on a "least seen" basis, where if multiple advertisements are running, the one which will be displayed will be that which is has been "least seen" (usually, the one running longest).
