G116.9+0.2 ADS: search fulltext or title/keyword/abstract

CTB 1

• Right Ascension: 23 59 10
• Declination: +62 26
• Size (/arcmin): 34
• Type: S
• Flux density at 1 GHz (/Jy): 8
• Spectral Index: 0.57

Notes: Has been called G117.3+0.1 and G116.9+0.1.

Radio: Incomplete shell.

Optical: Filaments on sky survey.

X-ray: Centrally brightened, with NE `breakout'.

Point sources: Pulsar outside rim to E, with radio tail.

Distance: Association with HI features implies 1.6 kpc, optical extinction suggests 4.3 kpc.
