Merkurpassage
Merkurpassage 8. november, 2006 med solpletterne nr. 921, 922, and 923
En Merkurpassage er det fænomen, at planeten Merkur passerer ind "foran" Solen, set fra Jorden. Dette sker 13 til 14 gange i løbet af et århundrede.
Da Merkur er tættere på Solen, og derfor også fuldfører et omløb om Solen (et "år") hurtigere end alle andre planeter, indtræffer merkurpassager oftere end det tilsvarende fænomen for planeten Venus.
De sidste merkurpassager var i 2006 og 2016. Den 9. maj 2016 var hele passagen synlig fra Danmark.
Den seneste var den 11. november 2019, der begyndte klokken 13.35 og sluttede fem en halv time senere.

The Historical Transit of Mercury on November 8, 2006. Please note that sunspot #923, which is just below the equator at the left-hand side, is much bigger than Mercury is. You could also see two more sunspots at the right-hand side at the equator. You could see Mercury as a small black dot in the lower middle of the solar disk. Limb darkening is clearly seen at the image. The picture was taken with a white filter and prime focus. The grainyness in the Sun is called granulation.
