The Real McGee

This is what the north side/down stream edge of McGee looked like Tuesday May 1,2018:




And the following were taken in 2017. First on Thursday May 4 when the Creek had a depth of 57cm at the "standard measuring place at the far side/upstream of the bridge.

Clearly deeper than yesterday - maybe by 20cm? making yesterday's depth 37cm approx.

Here is a ruler


I observed some snow in the bush but generally Spring has returned for another year.

Generally, down streamed looked like so on May 1, 2018

:





Upstream McGee looked unchanged:







For practical purposes, the sun is infinitely far away and so the rays casting my shadow are parallel
and so my shadow hand is also 9cm across, and my head shadow 16cm - in the picture. (As measured here at home with a ruler.)

Sun and Moon and Venus and Mercury

I was reminded tonight at the camera club that I had not completed night sessions from Sunday March 18th

There were 7 of us on Saturday, 3 on Sunday Mar 18, 1/me on Monday Mar 19 and 3 on Tue Mar 20 (this time with no camera).

Here is what the sky looked like on Sunday March 18:



The moon was difficult to see at first.

















Matching exposures to pick up all three:


 Moon lower left,                                   Venus centre                    and Mercury between the red lines


To show how rapidly the moon moves relative to the line Venus - Mercury, I took some images from the earthobservatory blog: as seen from Spain 6 hours earlier:

by Annie Lewis in Madrid.


From Lakeland Florida:


by Michael Holland.

Mine when the moon was 34h 57m old:

The angle to the horizton is a function of the latitude of the observer - I was further north than Michael Holland in Florida.

And finally from Mike Morrison in Seattle Washington, approx 3 hours later:


So the moon does move!
