The explanation starts "As its June 6 2012 transit begins..." but in information brought up through links the photo is mostly stated to have been taken on June 5 (though to add to my confusion some also state June 6 as well as June 5 in information in the same link, such as through a link to the Hinode section in Flickr). From my understanding of the transit I would have said the photo was taken on June 5 under Universal Time but I'm now unsure. :?
I'm sure you're correct. By Universal Time, the transit began on 5 June and ended on 6 June, with the majority occurring on 6 June. The position of the Hinode spacecraft only alters the apparent timing with respect ground-based observations by a few minutes. So this image had to have been made around UT 22:30 on 5 June, give or take a half-hour or so.
