Sky At Night

Sky At Night

A Report of Facts & Fiction..!


Venus, Jupiter & the waxing Moon.

My friends had gone before me as always and was getting ready for a busy night session. I reached the dark site, just at sunset. 

After the initial greetings and settling, we noticed till late evening a dozen or so, bright and faint, slow and fast, steadily moving star-like, but untwinkling points of light (satellites) with naked eyes, some followed up in binoculars. 

There has been a recent (unlike a decade ago) increase in the number of these objects. Some looked bright like Jupiter and disappeared suddenly. Some just flared for a few seconds to disappear. Some very  faint and slow moving. Some in polar orbits moving from south to north while others moved from west to east but not exactly east-west but angled. 

As usual, I began looking west starting with the proceeding to set Venus and Jupiter. Moon had separated further and had risen up growing in its phase. The moon's orbit is angulated to the planetary alignment to puzzle any observer let alone a beginner. It's interesting to watch this fact.

Uranus, in Aries (Ram), was not seen, unlike the day before yesterday evening, to confidently assert, due to adjacent position of the cresent moon. Auriga clusters M36, 37, 38, looked faint in binoculars due to the moon light. M41 near Sirius (Siva) and M35 in Gemini, being away from the cresent moon, were better observed. M44 (Beehive), and in the early morning M13 in Herculus, M7, M6 to the east of Shaula (Moola nakshatra), observed. Omega Centauri was easy to spot in binoculars. Sagittarius Milky Way was increasingly better appreciated as it climbed towards the meridian. 

Pleiades and Hyades were traced maximum. 

Faint elusive constellation Monocerous was traced fully, with the help of chart and binoculars. 

As I am interested in the scientific study of religions (theology), different world cultures and the history of astronomy, I state the following ideas, and my understanding of the same - mythologies, stories, allegories and all, with  associated astronomical significance :-

In Hindu puranas (mythology) and religious worship, Lord Siva is worshiped in Linga form as an embodiment of symbolic representation of male and female energies of our dipole universe. Only the formless gets a form - shape - structure & function, with the passage of time. The Shiv Linga and Yoni together represent this dipole function of creation, sustenance and dissolution of this material energy forming into the universe. 

Now, the summer constellation Ophiuchus (serpent bearer), looks like a Tanjore doll north of Scorpious. Ophiuchus body is circled by a giant snake, from its east to its west, called Serpens Caput and Serpens Cauda, forming its head and tail. On the north east (lop left) of Ophiuchus we also can find Corona Borealis (the crescent moon). 

There has certainly been a sharing of ideas between the Hindus / Indians and Greek astronomers, as there are common representations in the sky only with different names and stories. A cultural give and take seems to have happened, in astronomy, mythology, and the pseudo-science of astrology, between the ancient Indians and the Greeks. 

Herculus, Ursa Major, Minor, Leo, Virgo, Corvus, Orion, Gemini, Crux, Canis Major and Minor were seen. 

Unlike last fortnight yesterday after midnight it became severely cold uncomfortable. We roosted in car. When I woke up at 3am and ventured out, my hands were cold and numb. It was cold outside. I thought, I could have better worn that leather jacket. The humidity was condensing as dew. There was haze, like a flickering-flame of fire, affecting sky  transparency. But seeing was good without turbulence. No boiling.

Aphthous Ulcers

"Recurrent Aphthous Stomatitis"


Aphthous Ulcers are sore;
I pray it not to bother more,
It is fond of children and teens,
But, may not leave the old by any means !

It is minor and major like us,
And waxing and waning like the moon !
It comes with a warning of pain,
And stays a week to push you to vain.

Do what you may it refuses not to return,
Till it taught you a deadly lesson !
And finally it helped us how to learn; 
And live without anxious concern.

A minor trauma by tooth bite,
Kills our mind-body being so quite.
Prevention is better than cure;
But here we are not so sure.

Tetracycline mouthwash may prempt;
But, Benzydamine may reduce pain;
Topical LA can be used, 
To eat and talk and shout amused.

It educates and prepares us to deal with severely morbid states -
As it strengthens our immunity to fight lethal cancerous ulcer states.
By having learnt to deal with emotional stress.

Avoid Stress and Be Blessed 🙌

Siva Rathri with Sivan

           Astronomy with Binoculars              Clusters of the Celestial Sphere   Oh...what a Night show !

Early morning sunrise.

It was a different night. Cold much reduced, but dwe was condensing after mid night. The early evening till midnight was clear without any clouds. But haze in the atmosphere, made me rate it as 05 in the Bortle Scale. 

As with last fortnight, I saw, about to culminate Orion and Auriga. I lay in the reclining chair and used my 10x50 Binoculars to view Andromeda galaxy, in the western sector. It was not a difficult task. 

I could easily pick out M36 the compact bright of the three, just inside the eastern side of the pentagon. M37 a bit bigger and fainter to the outer side and M38 much bigger and fainter just west of M36, but much nearer than 37 is to 36. They formed a small non-equal triangle with M36 at the apex, in my 6 degree field of view. Sweeping down south and east I was able to see M35, at the tip of Gemini. A conspicuous loose cluster, looking like M38 but much brighter and bigger. 

Moving to Sirius and sweeping down south i could easily see M41. 

There were a couple of satellites for early evening, late evening and early morning totalling 10 in all. A couple of satellites crossed my binocular field criss-crossing in two directions, They looked brighter, faster, and nearer. There were a few meteors and high flying birds mimicking satellites.

Constellations Virgo, Lupus, Draco, Ursa minor, Herculus, Corona Borealis, Coma Berenices, Corvus, Ophiuchus, were traced full.


M4 was spotted near Antaras and M33 in Herculus.

The Dance of Shiva, this gigantic cosmic dance of vibrating molecules and atoms in the soil, air, rocks, water, and in our own bodies - this cosmic dance of energy, the rhythm of it is felt and the sound heard under the starry sky ! 


Colours & Intensity of some Bright Stars

Variable star BU Tauri, in Pleiades observed. I counted 11 stars in the group, with Binoculars. 

With the aid of Stellarium, we could locate Planet Mercury, currently in the constellation of Capricornus. It appeard as a bright steady untwinkling star with a golden hue. It was visible for sometime even when I missed the moon for a while. 
Its given Mag is - 0.29 with RA 20h 48m 50s & Dec -19° 22' 23”. Around 6 AM, planet Mercury appeared above to the north-west of a 2% lit waning cresent moon, being at the 11-o-clock position and the moon at 4-o-clock position in the same binocular field. Moon was stunning to look at nearar to the horizon in the moving partly dark cloud covered eastern horizon. For a few moments it was also seen with the naked eyes, along with the moon.
