Time period limitations

Starts

Here you can select the time from which the observations will be displayed. The last month will be used by default. In this case, the search results in the middle of the page will show the findings reported to the Skywarden during the past month.

By clicking on the word 'ends' with the mouse, you will also see the end time of the search period. This is useful in situations where you want to look at observations from a period in the past, such as reports from a particular week in Skywarden.

Especially when looking at observations for a particular time period, you may want to do the search based on when the observed phenomenon actually happened instead of the time when it was sent to the observation database. In that case, you may want to select 'Observed' instead of the default 'Sent'. Please note that the browser uses a cookie to remember your choice of the start time of the search. If you have enabled cookies and do not clear them from your browser's cache, the same browser will display observations from the same time window you last selected the next time you use it.

Visibility

You can choose to show only phenomena of the desired level of visibility in the search results. For example, "at least III" removes the phenomena classified as the weakest (I-II). Similarly, "at least V" removes from the results all but the relatively rare phenomena or those classified as very impressive (V).
Free text search

Here you can do a free-text search to the observations

The given text will bee searched from observation titles,descriptions, technical details and identified phenomena
Observer and team

You can search for any persons observations by writing the observer's whole name or part of the name here. For example 'John Smith' or 'John S'

You can also performa a search based on asspciation/team name or part of the name, like "Lahden Ursa".The search will bring up observations, that exactly match the given string.
Observation location

To find observations made in some specific location, type the municipality name to the search field. For example, "Mikkeli"

You can also list multiple locations by separating them with a comma.For example "Mikkeli, Hirvensalmi, Juva, Kangasniemi". In this case, the search will return findings that match the locations listed.
Search from identifications

In this field, you can search for more detailed phenomenon identifiers included in the observation details.

Such are, for example, deep space object types such as "spiral galaxy" or "reflection nebula" or halo forms such as "sundog" or "sun pillar".

You can also list multiple types of phenomena by separating them with a comma. A search will bring up findings that match one or more of the terms you listed.

By narrowing down the search date limits and typing, for example, "northern lights", you can see all the northern lights seen within a certain time period.

Rising really slowly from the northeast. At first only one matte belt, after which it turned into waves as it expanded. Images again in shooting order.

Koillisen suunnasta todella hitaasti nousten. Alussa vain yksi himmeä vyö, jonka jälkeen se muuttui laineiksi laajetessaan. Kuvat jälleen kuvausjärjestyksessä.
