Hi all,

Òš

1. MERCURY + VENUS: Mercury continues its favourable evening elongation, close to bigger and brighter big sister Venus.

ÒšÒšÒš OnÒšthe evening of 2 April Mercury will lie only 3ÒÀ just below and right of Venus. Mercury slowlyÒšgets closer to Venus, approaching from the right as we look at it,Òšand about level above the horizon with Venus. The separations about 30 mts after local sunset are:

2 Apr: 3ÒÀ 4ò??; 3 Apr: 2ÒÀ 59ò??; 4 Apr: 3ÒÀ; 5 Apr: 3ÒÀ 3ò??;Òš6 Apr: 3ÒÀ 8ò??; 7 Apr: 3ÒÀ 16ò??; 8 Apr 3ÒÀ 27ò??.

ÒšÒš Mercury's magnitude fades from -0.1 to +0.6 over this period, so the difference in brightness between it and Venus will become even more pronounced.

ÒšÒš By 15 April Mercury will have moved back to about 7ÒÀ below right of Venus, and faded to mag +1.1, but on that evening you have a rare chance to see the Moon closer to the Sun in the sky than Mercury! In mid twilight, the very thin crescent Moon will lie 1ÒÀ 40ò?? below and right of Mercury. Mercury may be the hardest to see ò?? if you see the Moon, draw an imaginary line from it to Venus, and Mercury will lie just slightly below and left of a point 1/5 of the way along that line.
