Two versions of a B,R,I colour composite of the M13 images from last night. One is 45'x32x and the other one 11'x8'. In the latter the colour stretch has been adapted to see the individual stars.

Thanks to Luke and Tosin. We have put the new cloud sensor onto the mast today and it is sending data. One step closer to making the observatory robotic.....

Barnard's Star (the bright one at the bottom) observed May 24th (right) and Aug 9th (left). A rough analysis shows it moved 2.1", i.e. it has a proper motion of 9.9"/yr. That's close to the real value of 10.4"/yr.

We had a very good turnout for the Perseid watching on Saturday. The clouds even stayed away for a few hours, so plenty of shooting stars were seen.

More data for the new Astro lab: Asteroid Amphitrite observed about one hour apart. Clearly moving - we observed it at the point of its slowest possible apparent motion. Task: Measure it's apparent motion on the sky.

Finally some good weather, and the mount has given up working again. We are exploring what might be wrong - first things unsuccessful. At the least it is still under warranty....

Our Fireball Camera also picks up Auroras. Below are a few processed frames from the Aurora on May 10 this year (22UTC). This one did not ruin any observations as the humidity was far too high on that night ;-)

While the observatory remains under a constant blanket of clouds ☁️☁️☁️ since October 27th, that last observing night has pushed our total time of taking science data over 6000hrs. 🤓

After a brief outage due to a problem with a cable, the fireball camera is now back operational since a week. And we detected a nice one on Thursday night.

The weather is terrible again 🤓

I think we broke our record of consecutive nights with at least some observing. We have now had 14 nights where at least some (from 2.25hr up to 9.9hr) observations have taken place. We observed for a total of 94.7hr in those two weeks. 🤓

Well, March had very good weather. We observed on 21 of the 31 nights and gathered data for a grand total of 131.39 hours. That is a new record for observing hours by month - beating February 2019 by 6 min 😁 - and more than twice the average for March.
