The Moon eclipses Mars on 10th May 08

Updates

Some reports first

The event was successfully observed at IUCAA Pune. The programme was conducted by Arvind Paranjpye.

Manasi Deshmukh-Shah was the time keeper giving observers the exact time count. Abha Vaishampayan (C8 telescope), Soniya Deshpande and Shrikant Vinchurkar (8 inch) timed the event. Dhruv Paranjpye observed the event with 42 mm refractor. Priyanka Charuvedi and Mukul Mhaskey used C14 with Philips web cam and recorded the event.

Samir Dhurde provided the crucial computer support.

We have uploaded the films captured. The reappearance took place just below Mare Crisium on the Moon. A sudden gust of strong wind shifted Mars out of the field at the end of it, but the most important part was captured. :)

Bedadyuti Chakraborty of Bioscope, the amateur astronomers club of Dr Reddy's laboratory, reports successful observation of the event from Hyderabad.

Mayuresh Prabhune, Khagol Vishwa, Pune, reports successful observations

Darshan Joshi, from Badlapur, reports observations with a 6" Newtonian telescope and binoculars, The following data is reported.
Time of disappearance : 19: 47
Time of reappearance : 21: 04
Time taken by mars to
disappear after touching lunar disc= 9.16 secs
reappear completely = 6.67 secs
The bright limb of the moon must have made the difference.

Amit Dhakulkar of HBCSE, Mumbai also observed it with his friends. He caught Mars on the limb of Moon, just before it disappeared!

100 odd participants from SPACE observed the event in Delhi. They used a meade 10" lx200gps f/10 to capture and put up this film.

Details of the event:

On Saturday, May 10, 2008, the Moon will come directly between Mars  and the Earth. This event is visible everywhere in India.

The map below shows the area over which the event can be seen.

The line colours have the following meanings:

  • Cyan - the curves of Occultation D or R at moonrise or moonset
  • White continuous line - the northern and southern occultation limits (graze paths), with the event occurring in nighttime
  • Blue continuous line - occultation limits, event in twilight;
  • Red dotted line - occultation limits, event in daylight.

Observers in India are well placed to observe this event. It takes place after about 7:30 p.m. Indian Standard Time (IST).  The exact time of the event will depend upon the location of the observer. The occultation timings for various Indian Cities are given in the table below.

For those west of India the Sun will be above the horizon and it would be interesting to see if the observers can spot Mars with respect to the Moon, which would be about 33% illuminated.

It would be a nice sight soon after the sunset with Mars just above the Moon.

the start of the event

On the day of the event angular diameter of Mars would be about 5.5 arc seconds. It would take about 13 seconds to go behind the Moon and about 10 sec to come out


Mars reappears close to mare Crisium. 

Normally it is not very easy to spot an object reappearing from behind the Moon, however, in this case with Mars being reasonably bright at 1.3 mag it would not be too difficult catch reappearance sequence.

As you observe this event try and rescored the following

  1. If you could see Mars in the broad daylight with the naked eyes.

  2. If you could observe its disappearance and how long it took for Mars to disappear behind the Moon.

  3. If you could see the reappearance and how long it took for Mars to reappear from behind the Moon.

In addition to your name please do send us details of your observations such as the equipment used by you (eye, telescope, camera etc.), your location, etc.

Please also tell us if you are organizing public viewing and if you would like us to announce it here.

We would like to display contributions like your observations, photographs etc.

Occultation
When one celestial body hides another one  behind it, astronomers call the event occultation.
By this definition, therefore, the solar eclipse is an occultation of the Sun by the Moon. 

Earthshine
During the crescent phase of the Moon, we can also see the other part of the Moon illuminated due to reflection of the sunlight from the Earth.
This is referred to as old moon in the new moon's arms 

Ashen light
 is a glow observed on Venus somewhat similar to the phenomenon of Earthshine found on the Moon, though dimmer. It is a yellowish-brownish glow in appearance and has been observed in some large telescopes.

Public Viewing at
Nagpur:
Ulhas Deshpande will
set up an 8 and 4 inch telescope
and 15X65 binoculars for observatons.
He also plans display the event
on computer using a web cam.

Occultation Predictions
Altitude of Mars at the time of the event is given in degrees. Sun Alt is the altitude of the Sun at the time of the event.
Please note that the predictions are accurate to within a second or two. The times are based on the Latitude and Longitudes of various station available. One is advised to start monitoring the event well ahead of the predicted time.

If you would like us to calculate predictions for your location, please send us latitude and longitude of your place, it need not be very accurate.

Some past events

Occultation of Venus or other planets by the Moon are  not very rare event though. The Moon does occults planets every now and then. On April 14, 2007, the Moon occulted Mars.

On  November 10, 2004, India witnessed occultation of Venus by the Moon in the pre dawn hours. That morning Venus disappeared at the brighter limb of the Moon. On May 29, 2003 India witnessed a day time occultation of Venus by the Moon,  that is the disappearing and reappearing act took place when the Sun was above the horizon.

The best event that was widely observed from India was double occultation of Jupiter and Venus. It took place on April 23, 1998.  The event took place around 1:30 p.m. local time. Many had claimed that they could see Jupiter with their naked eyes, close to the brighter limb of the Moon.

 
Suhas Gurjar, Pune,
took this photographs Venus, Jupiter and Moon on Apr 23,1998, just before the sunrise

Prior to this, double occultation of Venus and Jupiter was visible from  the Indian Ocean on August 18, 567 AD.
