How do I activate a light? A. See this ARLHS FAQ. Q. What does the "H" mean in the "C" column? A. The "H" indicates a "historical" lighthouse. Q. What is a "historical" lighthouse? A. A historical lighthouse/lightship, indicated by "Historic" in the Classification column, is one that no longer exists. It has been destroyed by nature or by man. In other words, our current sources have found no light at this location. Nevertheless, in historical terms, it may still qualify for our proposed "Ancient Award" and others; so we continue to include it on our list. For example: Mobile Point Range Rear, AL USA-506 Historic If a lighthouse that has been moved from it's original location, and not placed at a museum or reactivated, the original location will be marked "Historic". The new location will NOT be assigned a number, and can not be activated. If a lighthouse has been moved from it's original location to a new location, and reactivated as an active aid to navagation. The new location will be assigned a new number, and the old location will be marked "Historic". Q. What does the "M" mean in the "C" column? A. The "M" indicates a "museum" lighthouse. Q. What is a "museum" lighthouse? A. A museum lighthouse/lightship, indicated by "Museum" in the Classification column, is a lighthouse that has been moved and converted into a museum, or moved to a museum for display, and NOT reactivated as an active aid to navigation. The original location of the museum lighthouse will be kept or added to the list as a "historic" lighthouse. It will have the same number as the "museum", but with an "H" added as a suffix to the number. For example: Colchester Reef (Shelburne Museum) VT USA-182 Museum Colchester Reef (Lake Champlain) VT USA-182H Historic Q. How do I add a lighthouse to the list, that I think needs to be added? A. Provide as much information as possible (name, latitude & longitude, a picture, etc.) to the Lighthouse List Manager ARLHS. Q. What procedure is followed in adding/updating/deleting a light? A. The following is the general procedure followed to update the list: 1. The information provided is researched. 2. If it is determined that an add/change/delete is needed, a proposal is posted on the BeaconBot. This allows the membership to make comments on the proposed update. 3. From 5 to 7 days after the proposal is posted, the update is made, and a message is posted to the BeaconBot. NOTE: If a request is made to add a new light, and the requester is planning on activating the light within a short period of time. Every attempt will be made to add the light ASAP. Q. What is meant by an "unassigned" number? A. A number can be "unassigned" for a number of reasons. 1. It was found that the light assigned to the number did not actually exist, or 2. It was found that the light assigned to the number was already on the list with another number, or 3. It was found that the light assigned to the number didn't meet the requirements to be listed. NOTE: Once a number is "unassigned" it is never reissued. Q. How are lighthouse numbers assigned? A. The number assigned to a lighthouse consists of two parts, a three character alphabetic prefix, indicating the DXCC country, and a three or four digit number that is assigned sequentially as the light is added. For example the lighthouses in Alaska are prefixed ALK, and those in Hawaii are prefixed HAW. Q. Where do the names given a lighthouse come from? A. Names, if at all possible, come from the "official" list of that countries lights. If the light is no longer on an "official" list, the most common name found will be used. Q. Why are latitude and longitudes shown only to the minute? A. They are shown that way because the ARLHS doesn't provide navigational data. We provide those coordinates to help someone locate the lighthouse. If you need exact coordinates please consult a navigational chart or the (NIMA) National Imagery and Mapping Agency listings.
