Main-belt Asteroid (493) Griseldis

Main-belt asteroid (493) Griseldis was reported of being active in the past. Its activity was detected on March 17, 2015 when observed with the 8-meter Subaru Telescope on Mauna Kea. Asteroid had "an extended feature" or a tail, which was not in the antisolar direction. Shortly after the tail disappeared and observations taken on March 24 and April 18 revealed no presence of this "extended feature". It was suspected a possible impact event on this asteroid.
I observed (493) Griseldis on Apr. 3, 2023 using a 0.51-m f/4 Corrected Dall-Kirkham Astrograph of SSO (Q62). No suspicious activity was detected (which would be rather surprising). It is 16.6 mag (G).

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.
