Saturn disappeared at 04h27 and reappeared at 05h20 BST. Amazingly the blanket of thin swirling cloud lifted 10 minutes before the point of ingress. The night was very windy however and the atmosphere was extremely wobbly precluding any chance of capturing surface details on Saturn. The difference in brightness between Saturn and the Moon necessitated creating a composite image to show both bodies visually.

Still no sign of brightening. I have made a number of exposures since April with none showing any sign of activity at T CrB.

We had unexpectedly amazing views of the aurora at latitide 52 degrees N on the night of 10th/11th May 2024. It is clear that the activity is visible entirely in the northern portion of the sky. The intensity hit KP9/ Extreme storm (G5) on the KP scale, a reading last seen in 2003.

Sketched with white and black charcoal on black paper at the eyepiece over 30 mins between 20h and 21h UT. Again, the sketch was started before the fall of darkness which makes the initial outlining of the main elements on the paper somewhat easier. It was a dramatic sight in the low, slanting light at the Terminator. The terraces on the the crater walls were visible at times though no detail on the surface of the central plain was evident in the conditions.
