NLCs on June 25, 2021

At June, 25, we had clear skies for the first time over the last days of bright NLC observations in Europe. OSWIN radar in Kuehlungsborn had been giving strong, late signals, and the meridional winds in the mesopause also pointed southwards. Around 22:15 local time, i saw the first announcements of NLC observations from italy (see also https://spaceweather.com/archive.php?view=1&day=26&month=06&year=2021). At that time, NLC were already visible in zenith. Around 22:45 local time (MESZ), the NLCs appreared even brighter and stretched from north to ~west (there's a forest in front), and above well beyond Arcturus.

Technical information of the shown image

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
