Compared to average temperature, May 2020 started quite normal. But after a week, temperatures went well below average. Comparison chart shows that last year the mid-May was actually very warm. Seems that summer waits itself this year longer than last year.

Today there was an outage that lasted somewhat three hours (about 2.30-5.30pm). Reason was fiber optic net maintenance work done by local network operator. Weather observation values are stored in database of the station’s local server (weewx), but needs to be manually transferred to webserver’s database.

According to statistics of Flightradar24 receiver at Weather Station Nagu, amount of detected aircraft within about 400 km radius from Nagu has now stabilized to about 200 per day. It will be very interesting to see how relief of COVID-19 lockdown actions will affect and how quickly that will happen. After all, Finland is one...

A good while ago, Station Master decided to switch off rain collector heater for this season. This morning that decision turned out to be a wrong one. The heater is now on, but rain will be recorded some hours later than actually occurred. Probably it will not be correct, too. It should be about at...

After being online for a month, Flightradar24 receiver at Weather Station Nagu (F-EFTU7) is ranked the third best in Finland! Globally the rank is currently 509th among thousands of radars. So the position is ideal. Maybe increasing the antenna mast height would improve rank further?

Station Master replaced the failing transmitter today with a spare part obtained from a friend’s obsolete Vantage Pro. That transmitter seems to work as should, which is great news! Then, the idea was to service the original transmitter by replacing the obvious reason to increased battery consumption, failed superconductor. After opening the cover, it was...

Troubleshooting of the ISS transmitter has proceeded. Probably the faulty component is this shown in the image.

Due to temporarily failed hardware (reason for that currently being unknown), there is data missing from database between March 6, 2020 at 7.30pm and March 7, 2020 at 6pm. This revealed a bug in the script that displays the minimum and maximum values of the current month on the front page. Minimum Barometer value was...

The transmitter unit of ISS started working after two battery changes, but it reports that battery status is low. This very likely indicates that the condensator of the transmitter unit has come to end of its life, so online status cannot be guaranteed to last long. However, there is hope for quick remedy: a friend...

Looks that the transmitter of ISS (Integrated Sensor Suite) has failed. Station Master is checking out the situation, but if this really is the case, outage might be a long one.
