For several weeks, Venus and Mars and Saturn have been visible in the pre-dawn eastern sky. Today at 5:49 am, a very clear pre-dawn sky allowed a view low in the east to see if Jupiter was also visible. Yes, it was. Planetarium software predicted this to be my ideal view. Getting a photograph was a challenge.
Jupiter was down low and in the glow of the sky. Mars and Saturn are both far away and dim objects. Adjusting exposure for Jupiter meant Mars and Saturn were not visible in the photograph. Adjusting exposure for Mars and Saturn meant Jupiter was over-exposed and not visible. So, I took both photos, then copy-pasted the Jupiter portion onto the photo that showed Mars and Saturn. They are still difficult to see on a small viewing device like a phone or tablet. The labels and markers should help.
This alignment should be easier to see after about April 18. Jupiter will be higher. You still need to get out there before the Sun brightens the sky too much.
