Astronomers say the event will be clearly visible across the country, with the moon taking on the characteristic deep red hue often referred to as a "Blood Moon". The eclipse will be one of the longest of the decade, with totality lasting more than 80 minutes.
In Johannesburg, the partial phase of the eclipse will begin at 7.27pm, with the moon entering total eclipse at 7.30pm. The spectacle will reach its peak at 8.11pm, before the moon slowly begins to emerge from Earth's shadow. Totality ends at 8.53pm, though the entire eclipse lasts until after 10pm.
Observers in Cape Town will also see the eclipse. Clear skies and an unobstructed view of the eastern horizon will offer the best chance of seeing the moon darken and glow red.
