Mercury transit observed at the Hvar Observatory, 09.05.2016

The transits of Mercury across the solar disk are rare phenomena, although Mercury orbits the Sun in just 88 days. The reason for this is that Mercury orbits the Sun with the certain angle to the ecliptic, ie. the plane that the Earth orbits the Sun. Mercury transit in Croatia was visible on 9 May 2016, started at 13:12h local time and could be seen for almost 7 hours. Unfortunately, end of transit was not visible from our region because the sunset was at 20:10h and end of transit was at 20:42h. This rare phenomena was possible to observe from Hvar, and it was recoreded in white light and H-alpha using Hvar solar telescope. The next transit of Mercury will be visible from the Croatia in 2019.
