Upside Down Plough
21 Answers
I've watched the constellation of The Plough turn from how I normally see it to standing on its tail to now being virtually upside down. I can't recall seeing it n this position in the whole of my 50 years on this planet. Is there something unusual happening, or have I just been un observant ?

This star clock can be used (in reverse) to find approximately what time in a given night The Plough will be standing on its tail. Greater accuracy can often be achieved by calibrating your star clock to your specific location by initially comparing the time indicated with the actual time to determine any adjustment to indicated time that might need to be used.
