Also Mercury is heading towards maximum Western elongation (29 April @ 27 degrees), we might get a look at it just before sun up in the Eastern sky. If you do go looking for Mercury as always be very-very careful. The Sun isn’t far away and you could be badly injured if you look at the sun, especially if you are using any magnifying devices.
