You can observe an Asteroid Occultation of 5.2 magnitude star on 6th of July. If any one of the members is interested, I can guide you about timing, how to observe and how to record the timing


Please share more details sir, if the sky is clear I will give it a shot.

On the 6th of July, a 5.3 magnitude star HIP 55716 will be occulted by an asteroid 2122 Pyatiletka for 0.6 seconds. The star is a really bright star, so easy to find. The centreline path will be from Kankavali (Maharashtra), going over Belgavi and Byahatti (very near to Dharwad) to Kazhipathur (South of Chennai)

The timing will be 14:48 to 14:50 UT, depending upon your exact location.

You can use Android App “SAT TIMER” to record the event timing and contribute to scientific data of IOTA (International Occultation Timing Association)

If any one interested, may ask details here, by giving your exact location


Hi. I came across the details about this Asteroid Occultation here:
But a lot of details just went over my head.
I also came across another website which shows the occultation path: BREIT IDEAS Obs

I have a few doubts. If I’m several kilometres (400 kms) away from the occultation path, will I be able to observe anything? Will there be a very slight dimming in magnitude or nothing at all? Could this be observed with a pair of 10x50 binoculars? I read in a website that for stars brighter than 7th Magnitude binoculars could be used.
