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
For the third night in a row, the aurora borealis in the images of the Hanakasalmi observatory's allsky camera. Now the northern lights remained in the northern sky and were quite modest compared to the previous ones.

Jo kolmas yö peräkkäin revontulia Hanakasalmen observatorion allsky-kameran kuvissa. Nyt revontulet pysyttelivät pohjoistaivaalla ja varsin vaatimattomina edellisöihin verrattuna.

ARC The arcs are wider than the bands and do not fold as strongly. The arcs are normally neither very bright nor active.
The arc is probably the most common form of aurora. When aurora show is a calm arc in the low northern sky it often doesn’t evolve to anything more during night. In more active shows the arc is often the first form to appear and the last to disappear.
The lower edge of the arc is usually sharp but the upper edge can gradually blend into the background sky. As activity increases rays and folds normally develop, and the arcs turn gradually into bands.

Bands are usually narrower, more twisty at the bottom, brighter, and more active than arches. Bands usually develop from arches.
Bands can form J and U shapes, sometimes even full spirals. The corona can also arise from bands. Bands are a fairly common form of aurora.

Näitä tallenteita on mielenkiintoista katsella :) seuraan muutenkin revontulikameraa. Välimatkaa on kuitenkin Saarijärvelle niin ei ihan samat näkymät taida olla. Tosin olen vasta aloittelija niin en tiedä :D Eilen kello 23.27 näkyi täällä yllättäen harsoa ja säteitä. Ei kestänyt kuin noin 10 minuuttia. Eikä mitään upeita muotoja tullut lisäksi mutta kirkkautta oli kuitenkin. Helposti jää huomaamatta näin nopeat tapahtumat.
Revontulet näkyvät samanlaisina suurella alueella, joten ei varmaankaan ole suurta eroa Saarijärven ja Hankasalmen näkymissä. Keski-Suomessa pohjoistaivaalla näkyvät revontulet ovat oikeasti Lapin yläpuolella. Sääolosuhteet voivat vaihdella paljonkin, joten voi olla että toisaalla näkyyy ja toisaalla ei näy mitään kun taivas on pilvessä.
Kiitos vastauksesta. Aina oppii uutta kun uskaltaa kysyä :)
