Las coordenadas de la SNR se dan en Simbad como: RA = 06 h 48 min 40,0 s y DE = +06° 26' 00". Sin embargo, el punto central de la elipse óptica está significativamente alejado de esto. .Utilizando el AdW, puede ser RA = 06 h 49 min 04 s y DE = +06° 20' 23". Esto da como resultado 54' x 37'. La eliminación de SNR G206.9+2.3 es muy inconsistente en la literatura. Esto se debe en parte a la baja intensidad del objeto, tanto en el rango óptico como en el de radio. Graham y cols. (1982) estiman de 3 a 5 kpc (9800 - 16 000 ly), mientras que Odegard (1986)
calcula sólo 400 pc (~1300 ly). Clark y Caswell (1976) afirman 2,6 kpc (~8500 ly). En cuanto a la edad, Leahey (1986) utiliza mediciones de rayos X para estimar la edad en 60.000 años.

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.
