Really Amazon ?

I have been a user since 2010 and user since 2013 (actually since the day it was launched). No doubt they do try to be the most customer centric company (at least in USA) as they call themselves. Even in India (specially in Hyderabad) I see Amazon winning the race among all other e-commerce portals. I have had terrible experiences with Flipkart where they had refused to take back defective items and delivered items extremely late several times. On the the other hand , with Amazon it has been a smoother experience. Even in India they appeared to have inherited the culture from USA helping out customers in genuine cases. Once they had immediately re-shipped a brand new sterilizer when the original one did not seem to work so that I don't have to wait for the return and repair process complete. My answer in quora. I have always been an advocate and honest about amazon because of such incidents. In this case as soon as the old item started working I immediately s…

Back to the clear skies.

It's been a while I have updated this blog. Lets start where I left. Satellite spotting ! . The monsoon is almost over and clear skies are not as rare as it was for last few months. Recently some of the planets have been clustering together to make conjunctions. I missed Jupiter and Venus's closest approach last month due to bad weather. Jupiter and Venus were so close that they could have been seen within the field of view of telescopes and binoculars. Apparently Venus was closer to Jupiter than Callisto, farthest of the Galilean moons.

Christopher Becke did make an attempt from the other side of the world. I think I got 4 blurry Jovian moons along with the Jupiter/Venus conjunction last — Christopher Becke (@BeckePhysics) August 28, 2016 I managed to catch the Saturn and Mars hovering around Scorpios.

And an Iridium flare and ISS pass at the same time.

Shooting Iridium Flares

Iridium flares are sudden flares reflected from one of the Iridium satellite which looks like a very bright (as bright as -8 magnitude) moving object in the sky , sometimes brighter than Venus (max magnitude - 4.7 ) . The satellite itself is very faint in the sky (around 6 magnitude ) which almost beyond naked eye limit and since they are moving fast they can not be caught in long exposure. (because light doe not fall on a single spot in the camera sensor). I have been lately addicted to spot and capture this.

 These are so bright during the flare that it can be easily seen even from the most light polluted sky. Here in this photo I could only see the bright stars. I could barely see a 2.8 mag star above 10 degree of southern horizon. Thanks to and its Android app I could easily notified well before the flare and track it live just before its appearance so that I can have my camera's shutter open.

 This particular time it was close to horizon during flare (abou…
