In a couple of weeks, Venus will once again transit the face of the sun, on June 5th and 6th specifically. The last transit was in 2004, but this won’t happen again in our lifetimes. The next transit will not be until 2117, well into the 22nd century. It would be interesting to observe this, but I am not aware whether it can be observed with ordinary equipment, such as you can make for viewing a solar eclipse. Does anyone know much about how one would observe a phenomena like this absent a very expensive solar telescope?
