Oh dear. Mea culpa. As you probably know, there is pretty much no parallax effect here. I hadn't updated the asteroid's (osculating) orbital elements for years - and I believed it when I ran the erroneous simulation in Stellarium and #Flora was in a different place. Here's an update. Sorry 🙃

Here in Australia the #asteroid #Flora misses the core of the #HamburgerGalaxy - in this animation, north is down (as in where I am) and each frame is 9pm Sydney time/date. Since Flora is 'only' 237m kilometres away and NGC3628 is 45m light years further, parallax makes a difference! 🔭🧪

The recent #Moon - #Pleiades #occultation was invisible from #Oz but here's one I saw in the #UK on 7th Aug 2007. I took some pics with a cheap compact camera and sent them to Rhod Sharp on the BBC's 'Up All Night' radio show - here's what he said - Need sound on 🙂🔭🧪
