In the full Narada Purana (Purva Bhaga) this is chapter 56, verse 106.
The dark, red-and-dusky sons of the Sun give bad results. The sons of Venus, which look like a star, are comets that give good results.
Simple meaning: Dusky comets of the Sun are bad. Star-like comets of Venus are good.
कुजात्मजाः कुंकुमाख्या रक्ताः शूलास्त्वनिष्टदाः ।
Red spear-shaped comets of Mars are bad. Fire-coloured comets of Agni bring comfort.
कृत्तिकासु भवो धूमकेतुर्नूनं प्रजाक्षयः ।
A comet in Krittika can mean loss of people. One on palaces or trees can harm kings.
सुभिक्षकृत्कौमुदाख्यः केतुः कुमुदसन्निभः ।
The lily-white Kaumuda comet brings plenty. The Avarta comet at twilight is not good.
