For, they will be chasing the once-in-a-lifetime event: witnessing the century’s longest solar eclipse from the closest quarter possible for citizens.

Eclipse Chasers Athenaeum — a group of, as the name suggests, eclipse chasers and astronomers — is organising the flight along with a travel company.

The aircraft seats come in four categories: the sun-side seats (offers the best view) on the right, the middle seats, the aisle seats and the earth-side seats on the left. While the eclipse would be least visible from the earth-side seats, enthusiasts on this side would be able to photograph the lunar shadow moving over the Earth.

There are 21 seats on both sun- and earth-sides.

“All sun-side window seats are sold out and a few earth-side window seats are left,” said Shruti Pandey, deputy manager (corporate communications) at Cox and Kings, which is organising the Boeing flight along with Eclipse Chasers Athenaeum. “We are not selling the middle and aisle categories unless enthusiasts seeking these seats are well known to the passenger on the window seat.”

This, Pandey said, is because those on middle and aisle seats will not be able to get a whole glimpse of the eclipse. “We do not want passengers on window seats to get disturbed.”

Taking off from the Capital at 4.30 am, the aircraft will fly towards and hold over Gaya, Bihar, till the eclipse time. The flight, the Pandey said, will intercept the middle of the eclipse shadow at 6.26 am at a height of 41,000 feet.  

Pandey said there will be customised games, activities and announcements on board to help the eclipse-chasers.
