ग्रहचारः केतवश्च
पक्षं पक्षार्द्धमर्केन्दुपरिविष्टावहर्निशम् ।राजानमन्यं कुरुतो लोहिताम्बुदयास्तगौ ॥ १६ ॥
In the full Narada Purana (Purva Bhaga) this is chapter 56, verse 16.
Say the Sun and Moon have a halo day and night, for a fortnight or half of one. They also look red at rising and setting. Then they make another man king.
Simple meaning: A long halo round the Sun and Moon, with a red look at rising and setting, can bring a new king.
उदयास्तमये भानुराच्छिन्नः शस्त्रसन्निभैः ।
Weapon-shaped clouds across the Sun foretell war. Donkey or camel shapes of bad omen bring fear.
याम्यशृंगोन्नतश्चंद्रः शुभदो मीनमेषयोः ।
A raised south horn is good in Pisces and Aries. A raised north horn is best in Gemini and Capricorn.
घटोक्ष्णस्तु समः कर्कचापयोः शरसन्निभः ।
The rising Moon can look level, like an arrow, a bow or a spear, depending on its sign.
