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.

The "Sent" -option retrieves observations submitted to the Skywarden during the selected time period, regardless of when those phenomena were seen in the sky.
The selection “observed” retrieves the phenomena that appeared in the sky during the selected period, regardless of when they were reported to the Skywarden.
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).
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
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.
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.
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.

Visibility III / V
The illuminating night clouds first began to appear between the north and the northeast. The focus then shifted north and finally the show began to fade even before the darkest moment of the night.
Valaisevat yöpilvet alkoivat näkymään ensin pohjoisen ja koilisen välillä. Painopiste siirtyi sitten pohjoisen suunnalle ja lopulta näytös alkoi hiipumaan jo ennen yön pimeintä hetkeä.
The night cloud vail is a vague thin night shining cloud with no clear structure.

Bands of noctilucent clouds are long, stripe like cloudformation.

On the upper left corner, rising bands are clear on the image. Whereas waves of NLC cover the bottom right side of the image. Photo by Juha Tonttila.
Waves of noctilucent clouds are short, close groups of clouds.

A blurred mask (USM) has been used in the second and triple images. In the last two-image gif animation, you can see the effect of blur on dim night clouds.
Toisinaan käy niin. että tavallaan turhaan hosuu näytöksen alussa, mutta nämä hiipivätkin pian pois näyttämöltä.
