April 30th, 2016
The final day of the elections! The tangible excitement! Everyone in the back of their minds knew who would win but were nervous nonetheless. I was leisurely sitting on the sofa, flicking through the news channels, hopes dashed that a second news would get preference for a few minutes in at least one of them.
“দিদি দেখ আকাশে সূর্য গ্রহণ হচ্ছে মনে হয়। তাড়াতাড়ি দেখে যা।” (Sister, something’s happening to the Sun! I think it’s an eclipse. Come see fast!)
“সে কি!” (What!) I rushed up the stairs to the terrace. Many fellow flatmates also came up with me and then rushed under the stark blazing Sun. How is it an eclipse when there’s not an iota of shadow visible? Putting on the goggles I had found beside me before coming up, I peered in the direction of the sky. There wasn’t any eclipse, at least grossly. Though what I saw, I’ve never seen before.
Later on, I got to know it’s a 22 degree halo. It occurs when water vapour freezes 5-10 kilometers above the surface of the Earth, turns into clouds containing hexagonal ice crystals through which the sunrays are refracted twice and then come out in the fashion of a large rainbow colored halo. Thus instead of coming in parallel rays to the Earth as sunlight usually comes, it gets diverted inwards and thus from our point of view it appears circular at the level where it got diverted.
This phenomenon can take place with moon light too.
This is rare for us, since 22 degree halos are more commonly formed in cold countries. Even though it had occured here previously in 2013, but I don’t recall about that. Usually they are seen before thunderstorms, as the meterological department reported that day.
Anyways I was stunned to see this, and thought, yes finally the Nor’westers are around the corner! The weather was too hot and sultry to think otherwise! The skies turned dark and promising later that afternoon, but disappointed us by clearing too soon. I was kind of outraged after that, I clearly remember. I mean, there was a beautiful sign in the sky, and now, NOTHING? I’m sure you would’ve felt that way too after enduring a month of 40 degree Celcius and above 80% humidity.
Still, now I feel we were a lucky batch of citizens witnessing a rare event on such an important day in Calcutta.
[For detailed explanation of 22 degree halo, see the Wikipedia page.]
Wow!! I have never seen a Halo before. We get to see only spectacular sunrises and sunsets in south India. You were lucky I must say to witness such an event. 😊

Really…..it was amazing, though hard to see for long as it was noon at the time. I bet the sunrises and sunsets over at your place are even more beautiful 🙂

I’ve seen such halos around the moon, but neve before encircling the sun!
Probably becaus it’s not very wise to look straight at the sun, especially if you’re wearing glasses (like I do 😉 )

Couldn’t look at it anyway, just glanced it for a second before I went in. It would be mad to stare at the Sun haha 😛 I’ve never seen around a moon though, and probably won’t happen here I think.

I don’t really know. It’s usually during winter, however the temperatures in outer space tends to be the same regardless from where you look? But then this halo might be much closer than expected?

it is much closer from the ground, within 10 kilometres (not outer space), and the ice usually forms when the temperature is cold, so yeah it makes sense it’s during winter.

Yeah, I know, but – you should be able to see it in Calcutta as in the rest of the world?
If not, it’s a bit puzzling?!

It doesn’t get so cold here unfortunately 😦 that day it did surprisingly, because there was a thunderstorm nearby and it lowered the temperature at that level, then coupled with the Sun’s rays created the halo. Even in winter, Calcutta doesn’t get that cold and the Sun heats the lower atmosphere up like always, indirectly, after the heat waves are emitted from the Earth.

I know! I’ve visited Calcutta at least a dozen times, but even over Calcutta there’s freezing temperatures once you get to 30 000 feet.
To the moon, however, the distance is something like 385 000 km 🙂

The moon looks very beautiful 🙂 I guess it also says that this phenomenon cannot always be explained. Who knows, maybe there will be a similar halo around the moon here. 🙂
