Transit of mercury - 11.11.2019 at 12.00 - 11.11.2019 at 18.30 Funchal, Madeira, Portugali Observation number 86516

Visibility III / V

Kari A. Kuure, Tampereen Ursa

Seeing the beginning of the Mercury overpass in Tampere was so unlikely that I decided to travel to Madeira to see the event, when it happened to be the nearest possible place where the overpass would be visible from start to finish.

After several months of preparation, we were on a plane and after getting to the destination we were excited about Monday's weather. The previous week was partly cloudy and the weather forecasts did not promise better weather. This time, however, the weather forecasts were wrong and the Sun pasted from a cloudless sky.

The observation cycle turned out to be weaker than desired, although at noon it was still quite valid. Similarly, atmospheric transparency (abundant humidity) could have been desired. Visually, Mercury was nicely visible on the telescope for most of the overpass, so at least that side was successful.

However, the photos showed a bad weather, but luckily every now and then a useful image was created. I shot a total of about 1,400 images during the overflow. Here are a few of them: The first is from the center of the crossing at 15.20 UTC, followed by pictures from the second contact and finally taken after the center. The weather was so bad at the end of the overpass that the pictures taken from it are not playable. Fortunately, visually I saw the overrun until the end.
