All times are Mountain Standard Time
More than one person can enter a time for the same eruption. Given multiple times within the known duration of a geyser, GeyserTimes.org will make one of the entries the "primary" entry and all others "secondary." Only primary entries show up in the daily log, but you can see the related secondary entries listed by viewing the primary entry.
For example someone may enter a webcam time of 1200, but an entry of 1159 or 1203 non-webcam will override the webcam time and become the primary entry.
The primary entry is determined based on the following (in order): exact, electronic, near start, in eruption, webcam, questionable, time entered (to break ties).
An "entrant" is the person that makes the entry into the database. This is the person's registered username. If you are entering an eruption, you need not supply this information because you are already signed in.
An "observer" is the person that observed the actual eruption and provided the eruption information. This could be anyone. This is useful to help remember who told you about an eruption. If this is left blank, it is assumed that the "entrant" is the "observer."
To identify an eruption of Old Faithful as a "short," mark it as a Minor eruption. Old Faithful eruptions marked as Major will be considered "long"s.
Please, please, please leave comments as detailed as you can about what you saw. This is especially important for webcam times. May also be useful for in-the-field observations for inferrred eruptions based on steam clouds or wetness or water levels, etc.
You can enter any information about a geyser that you observed if you feel it is valuable. Even if it didn't erupt! Enter such information in the comments section and leave the eruption time blank. You must include the date that is associated with the information. For example, Beehive has been erupting at least once a day for weeks, but then doesn't erupt. You can enter "I watched Beehive all day from 0530 to 2130 and it did not erupt."
