Sunset, ananta chaturdashi

Yesterday was the big day for Ganapati immersions, the day before the full moon. As if on schedule, the clouds thinned and the sun came through. The rest of the festival season can now be counted out in cycles of the moon. In some traditional luni-solar calendars, the month of Bhadon would be half over now, and the rains will begin to peter out. In the corrected official calendar the month will end six days later than traditionally. It is difficult to make predictions, especially about the future (as a Dutch parliamentarian is reported to have said). No one really knows how much longer the monsoon rains will last, but I guess I will be able to walk more often.

August saw fierce rainfall and monsoon storms. On my first walk by the sea after a month I saw several things that have not been cleaned out yet. I wonder where this now-rusted barrel fell into the sea. What a wonderful happenstance that it washed up where I could use it to take a photo of the sunset. Plastic waste is never so useful.

To dream, perchance to sleep

The weekend was completely free of rain. The clear skies and wonderful sunsets drew The Family out to the sea shore. She would come back gushing about the light, and the number of people who came to quietly watch the sunset. So yesterday, I took my camera and climbed up to the terrace on the roof of our building. The western edge of the terrace is lined with satellite dishes, and each of them served as a perch for a crow, sitting quietly and looking at the sun. They were a little distracted when I appeared, and were torn between watching the sunset and keeping a wary eye on me.

“When our minds are much affected, so are the movements of our bodies,” wrote Charles Darwin in his book The expression of the emotions in man and animals (1872). This observation started a whole scientific enterprise of understanding the value of emotions by comparing them in humans and other mammals. Much less is known about the emotions of birds. “Birds and mammals are thought to have evolved from different groups of Mesozoic reptiles … during the Carboniferous or Permian period. Yet, birds and mammals exhibit extensive convergence in terms of relative brain size, high levels of activity, sleep/wakefulness cycles, endothermy, and social behavior, among others,” says a recent review of the literature on negative emotions in birds. Little else is known about emotions in birds. But when I see crows watching the sunset, or soaring against the breeze as the sun goes down, the parallel with human reactions to the beauty of sunsets does not seem farfetched.

The clear air of the last few months, and the relative coolness of the last few days meant that the sunset showed a simple gradation of colour in the sky, so different from the strangely beautiful sunsets that we had seen until the previous weekend. As the sun set, The Family and I enjoyed looking at so many different kinds of clouds. The horsetail streaks of cirrus clouds 5 or 6 kilometers above looked white in reflected sunlight because the sun had not set on them yet. As the horizon rose above the sun, the most spectacular were the golden layers of altostratus clouds at a height of about 3 kilometers. Meanwhile, the fast drifting layers of cottony stratus, merely a kilometer or two above our heads, had already started looking black because they no longer caught the sun.

The moon was already up in the east. As colour faded from the sky, the last clouds to turn pink were the high streaks of cirrus: ice crystals condensing out of the air in the cold of the upper atmosphere. The city lights came on, to add a glow to the moonlight. Between the clouds and lights, there is no way we will catch a glimpse of comet Neowise.

Post-human sunsets

Long after the microscopic soot from human pollution has been flushed out of the air, when only the greenhouse gases remain to heat up the seas, what would sunsets be like? We got a look at that during this nearly rain-free week in Mumbai. It was so spectacular that The Family changed the time of her daily walk to synchronize with the sunset. Cameras rarely see what the human eye does, but you may still get a sense of what we have been seeing in the slideshow below.

Soot and other particles in the air are relatively large, and serve only to dim the colours of the sunset. The colours are brighter when they have settled out of the air. Normally we see these monsoon sunsets at most for a day after heavy rains, before traffic pumps particles into the air and obscures them. Now we can see it for days on end. I understand now why people are calling this time the anthropause.

In cold and dry air, the colour of the sunset comes from sunlight scattered by molecules of air. The result is a gentle wash of light, changing colour from east to west, and intensity in the north-south angle from the sun. The sunset colours of tropical monsoons come from a more complex process: the sunlight scattering from aerosol droplets of moisture in the air. This explanation can be developed using a scheme invented by Gustav Mie. I wonder if he saw colours such as this during his youth in the German port of Rostock.

In any case, we are seeing the sunsets on a hot and wet earth, free of ongoing industrial pollution. These are the colours of the postanthropic world.

Ludicrous monsoon sky

This annoys me. Just look at that ludicrous sky, a splash of colour that any child with a messy paintbox can scrawl on to paper. I just had to take a photo to vent about it. Look at that wash of yellow at the bottom: what an inept attempt to show the blaze of the setting sun. If this was entered in a competition where I was a judge, I would sentence it to a hanging.

Others found themselves looking at different parts of this artist’s work. Here is a view someone drew my attention to: east across the Oval to the clock tower of the University with the concrete shell of the stock exchange looming behind it. At least this part looks like a competent watercolour, not the random splash of the sunset.

But then there is this view that another person pointed out, looking northwest at the city’s skyline. Again, the same amateurish dribbles of contrasting colours, and a very ham-fisted attempt at balancing them out by putting a red building on the right and blue buildings on the left and across the bottom. Really! I’m looking forward to the normal grey of smoke and car fumes to damp down the lurid imagination of this artist with the large canvas.

Just another Sunset

Locked down at home, there is time to look out at the world around me, even with the (literally) hundreds of emails that I need to assign to the “read” folder every day. That’s what life must have been like to the new humans of a million years ago: hunt all day and sit and look around you the rest of the time; no rushing about, so no need to constantly look at watches. The result is that I re-discovered ancient means of time-keeping. There is the quick passing of the day, the sunrise which now wakes me up, the change in the quality of light through the day, and the sunset, full of alarmed birds calling loudly.

But there is a longer passing of time, which I’d not paid much attention to earlier. It is still early in spring time, and I can see the earth slowly wobble in its daily rotation. As a result, the sunset is still moving northwards. I live in a city, so the horizon is interrupted by tall buildings. I’ve been noticing how the sunset was first blocked by one building, before I had a clear view, and now another building is slowly coming in the way. Lucky me. If I didn’t have these buildings I might have had to start hauling large blocks of stones around to build my own calendar.

Three postcards from March

March is the cruellest month in the mountains. We often go for a short holiday to the Himalayas in March. The roads are usually open, but the weather is unpredictable. We found a hotel in the Garhwal Sivaliks where we were the only guests, and our room had a spectacular view. Our last day there had been clear (photo below) but clouds began to come in over the high peaks just before sunset. Sunset and sunrise paint the snow in glorious colours. The clouds muddied the colours.

Dawn had been even more cloudy, but it had cleared up soon after sunrise. During breakfast we kept our eyes on the clear view of the mountains. The day was great and the view was wonderful. We decided to travel along a route which would keep the high Himalayas in our view most of the time. This was a day when our luck held, until sunset.

March is cruel. The weather keeps changing, and predictions are not accurate more than a day in advance. When we arrived at the hotel the view we had was spectacular for a photographer (above) but disappointing for a traveler. Every year we keep telling ourselves “Next year we’ll come to the Himalayas in April.” Maybe next year we will.

Sunsets in Guangzhou

Let me end the year without fuss with two sunsets from Guangzhou. The city once known as Canton is a place where the water and solid land intermingle. It is a city of islands and bridges, perfect for sunset photographs.

This was an interesting year. Hope your next one is even better.

Sunset glow

For a few evenings there was a beautiful yellow light which would bathe the world around us after sunset. As the red glow on the clouds faded, moments before it turned dark, the world would become a magical yellow. If you mentioned this to someone on the streets of Mumbai, they would smile and agree. The featured photo was taken quite a while after sunset; you can see that the camera, while trying to compensate for the light, makes a blur of the birds.

Land beneath the trees

This is not a light we see every year. After the monsoon the skies are generally clear of dust. If there is the normal pollution of the city, it just creates a haze and reddens the sunset. This colour came with a clear view of the horizon. It wasn’t even as humid as it could have been. It was a mystery until people started mentioning a raging fire on Butcher Island, off the coast. The fuel that is stored for ships on this outer island had caught fire and it took days to bring the blaze under control.

Light effects at sunrise and sunset depend so much on what the air contains. Moisture, dust and smoke are all things that produced beautiful sunsets. What was this due to?
