Notes: |
Images show current/recent sky conditions from my observatory Updates are only operational between sunset and sunrise. Videos are from the most recent full night of successful All Sky Imaging. This will normally be from last night, unless imaging has failed or is otherwise offline. Please click on the video or the play button to start the video. |

The following plot is rotated and flipped E/W to show a view that complements the typical view one has standing in the observatory next to the Telescope and looking south in the sky with east on the left and west on the right. It's a hypothetical view as if one was looking down on the sky from above. Whilst constellations appear mirrored the rotation of stars and moon in the the image are consistent with the direction we actually experience.

The keogram plots below show a time ordered compilation of single
E-W and N-S columns taken from each AllSky image through the night Times shown are Local Time (LT ). A keogram captures the flow of time from dusk till dawn as its left-to-right horizontal axis. The word 'keogram' was derived from keoeeit, the Inuit word for the Aurora Borealis. Dr. Robert Eather developed keograms in the mid 1970s as a way of visualizing the output of ‘scanning photometers’. He had the fantastic insight of realising that if this data could be assembled by a computer it could create a single image of all aurora activity throughout the night. |
