A powerful solar storm is expected to reach Earth tonight, creating a rare possibility of aurora sightings in parts of northern India. Space weather agencies have issued a geomagnetic storm watch for June 8 and June 9 after a massive cloud of solar material erupted from the Sun and began moving toward Earth. If conditions remain favourable, skywatchers in some Himalayan regions could get a glimpse of the colourful "dancing lights" that are usually seen much closer to the Arctic.
