Phases of Venus in 2015 (March to August)

Now for past two months or so we have been observing Venus shining brilliantly above the western horizon.  Observing from about 25 deg north latitude during this western appearance the planet does not move too much in azimuth. Presently it is moving  northwards a bit.  From 1st of March till 15th May its azimuth changes by about 17 degrees and climbs by about 23 degrees above the horizon.

Venus shows phases like moon and these can be easily observed even with a small telescope or binoculars.  Some people with good eyesight can actually make out the phases of Venus without any optical aid.

Plotted below are the positions of Venus from March 1st to August 3 for 7:30 p.m. (local time) as would be seen from 22deg latitude.  To show the phases of Venus, on this scale, the angular diameters plotted are highly exaggerated.

You can use these images:  As a matter of principle I do not attach any copyright to my work that is meant for the public outreach.  You are, therefore, free to use these images for astronomy and science outreach. And if you did use these, I shall feel happy if you let me know how and where.  If you want hi-res images of these do let me know I will be happy to provide those too.
