Moon – Jupiter – conjunction 31Oct19

Opportunity for a trial for the event of occultation of Jupiter by the Moon is coming up on 31st of October.

Just at the sunset it will be easy to spot the Moon. Jupiter will be less than two degrees from the Moon.

The map above shows location of the Sun at sunset, Mercury, Venus, Antares, the Moon and Jupiter.

Caution

Moon is 40 deg and Venus is just about 20 deg from the Sun – be very careful not to point your telescope in the direction of the Sun.

You may start the exercise about an hour and half before the local sunset. In Mumbai, the Sun will set at 6:06 p.m. that evening and so Mumbaikars my consider starting their observational exercise by about 4:30 p.m.

First try looking for the lunar crescent above the western horizon. If the sky is clear then you should be able to see the upper part of the Moon illumined by reflected sunlight from the Earth. Check slightly to the south east, that is to above and to the left of the upper limb of the Moon. See if you can spot Jupiter.

If you cannot find it in the first attempt then continue to watch. And note the time when you first spot Jupiter.

This exercise will be helpful in identifying Jupiter on the D day. Though that evening it will be lot more easier to spot Jupiter as it will be closer to the limb.
