A quick tutorial on magnitude. The magnitude scale is an inversal scale, meaning as the magnitude increase, the apparent brightness of an object decreases by a factor of about 2.5. So the greater the magnitude, the dimmer the object, and vice versa. The lower the magnitude, the brighter the object by a factor of 2.5. The dimmest that you can see under optimal conditions is about magnitude 6. Any magnitudes greater than 6, you'll need binoculars or a telescope to see them. A magnitude 7 object is 2.5 times dimmer than a magnitude 6 object, while a magnitude 5 object is 2.5 times brighter. Any of these objects that I'm talking about, especially the planets here, definitely point a telescope or binoculars towards so you can see much more detail. You can definitely see them with the naked eye, but definitely put a scope on them as well to pull out all the intricacies of what you see. Venus is rising about 3.15 am this week. Look for a match to the southeast by an hour before sunrise. Venus moves from the constellation of Gemini into Cancer, shining at magnitude minus 3.9 on the 15th. Mars is setting about 9.45 pm this week. Look for Mars to the west in the evening. Mars is in the constellation of Virgo, shining at magnitude 1.6. Jupiter is rising at about 3.15 am this week. Look for Jupiter to the southeast by an hour or so before sunrise. Jupiter is in the constellation of Gemini, shining at magnitude minus 1.9. And then we have Saturn. I'll let this thing reset and then tell you about Saturn.
