Moon Occults Epsilon Tauri Jan 07, 2020

**** All times in IST ****

On the night of January 07 the Moon passes from the north of Hyades cluster. That night it will occult seven stars brighter than 8th magnitude. <check this link>The first event is at 7 p.m. and the sequence ends at about 2 a.m. on January 08. One of the stars is Epsilon Tauri (mag 3.5) or Ain (Arabic عين for “eye”).

This series of events are take place when the Sun is well below the horizon, which is good. But the Moon is nearly 88% illuminated, which is bad.  The disappearance takes place takes place at the darker limb of the moon, which is good. But you will need smaller field of view – not so good.

You should be able to observe the event using a 100 mm (4 inch) primary .  But see to it that the eyepiece field of view not much more than a quarter of a degree. Else glare from the Moonlight might be too disturbing.

Some details of occultation of  Epsilon Tauri (mag 3.5) are given below.

It would be possible for us to compute the re and dis app

The Moon map and occultation track below will give you the general information of where to look for Jupiter with respect to the lunar profile. The number corresponds the station number given above.   Eg. 6 corresponds Nainital .

This world map below is a Mercator projection showing the basic circumstances of the occultation. The time of geocentric conjunction is listed at the bottom of the map.

 The line colours have the following meanings:
Cyan – the curves of Occultation D or R at moonrise or moonset
Blue continuous line – occultation limits, event in twilight;
Red dotted line – occultation limits, event in daylight.
