In the full Narada Purana (Purva Bhaga) this is chapter 56, verse 14.
A Sun shaped like a pot brings fear of hunger. Shaped like an arch, it may harm the city. Shaped like an umbrella, the country may be struck. A broken Sun may put the king's life at risk.
Simple meaning: Pot, arch or umbrella shapes on the Sun point to hunger and harm. A broken Sun points to risk for the king.
उदयास्तमये काले विद्युदुल्का शनिर्यदि ।
Lightning, a meteor or a thunderbolt at sunrise or sunset can point to danger for a king, or war.
पक्षं पक्षार्द्धमर्केन्दुपरिविष्टावहर्निशम् ।
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.
