G120.1+1.4
Tycho, 3C10, SN1572
- Right Ascension: 00 22 30
- Declination: +63 52
- Size (/arcmin): 8
- Type: S
- Flux density at 1 GHz (/Jy): 56
- Spectral Index: 0.61
Notes: This is the remnant of the Tycho's SN of AD1572.
- Radio: Shell, brightest to the NE.
- Optical: Faint filaments/knots to the NNW, NE and E.
- X-ray: Shell, coincident with the radio shell, brighter to the NE.
- Point sources: Faint radio source near centre of the remnant, thought to be extragalactic.
- Distance: HI absorption gives 4--5 kpc, optical proper motion and modelled shock velocity gives 2.3 kpc.
