Title

Venus night side detection anomalies

About this image

Throughout September I have taken every possible opportunity to try to detect heat features on the night side of Venus. On two successive pre-dawn mornings, 9th and 10th September, with identical equipment I detected some differences - brighter areas - not explained by any movement of the surface between the two days (Venus rotates extremely slowly so features only move a fraction in 24 hours). I couldn't then obtain any good data on Venus until 15th September where the brighter areas from 10th September had now disappered but two potentially new brighter areas had appeared. At the narrow wavelength observed 96% of data is purely from the surface heat of Venus. It is possible that transient cloud has also been detected but the bright areas do appear to be following the contours of Venus. A mystery for now but something of interest. Martin Lewis's images of 9th and 15th also spotted similar transient features.
