Processed using low resolution color images (IR, Green, Violet) from March 29 1998 overlaying higher resolution unfiltered images taken September 26 1998. Map projected to Mercator, scale is approximately 225.7 meters per pixel, representing a span of about 1,500 kilometers.

This is the time-lapse of processed images leading to the impact on Jupiter March 17. The original purpose of the imaging session was to get this time-lapse, with a happy coincidence of the impact in the second last capture of the night.
Each of the images in the time lapse are clear because they have been processed from 55 seconds of video. the impact itself however only lasts less than two seconds, so I have shown this part without processing.
The time lapse was made using an 11″ SCT with an ASI120mm camera and Ir-pass 742nm filter.

Jupiter Venus rising over Cork city on Friday night..

Over the next month keep an eye on Venus-Jupiter planetary duo as they quickly begin to converge in the sky. This weekend the two will be separated by about 23 degrees; by the end of the month it will be half that, and by mid March they will be less than 3 degrees. That’s equal to the width of your three middle fingers held at arms’ length!
Thanks Karl Woodhouse
