A big thank you to the new participants that help us with the data processing. We have now almost 82,000 images in the database and over 2 million photometry data points have been added since we re-opened the server. Our backlog is still over 4,000 images, so there is more to do – any new volunteers are welcome, please get in touch.

Work has now started in the background to re-instate and re-organise the full database, including a cross-match to the Gaia catalogue of stars. This will immensely speed up the search for light curves in the future and also help us to implement an alert system for stars that are changing their behaviour. Note that in the meantime, the light curve search feature will only return data that has been entered after the start of April 2023. In some cases this will mean that no data is returned.

This week we look at an example of a light curve we have looked at in the past (week 92, week 160). The star V350Cep is located in the NGC7129 star forming region and showed a deep dimming event at the start of the HOYS observations. Since then, its brightness has only slightly changed on longer timescales. The new data, distributed just over a few months, is in line with this behaviour. We will have a new PhD student starting in September to analyse the longer term light curves of all the young stars in HOYS to study the structure of the circumstellar disks.
