Denver Colorado eclipse viewing information for the Great North American Eclipse of April 8, 2024

Location identifier and latitude/longitude

The times in the table have been calculated based on this exact location. Times can shift by several seconds as you get several miles/km away from the location shown.

start time of the partial phase ( ” C1 ” )

All times are given in local time or Universal time [UT] (also known as GMT or Zulu time). You can convert the entire table by clicking on the time zone you want to see it shown in!

Where to look for that first “bite” of partial eclipse (“V”)

We’ve called this value “V”, because that’s what astronomers call it. If you imagine the Sun’s disk as a clock face, this is the hour hand value of where to look on that “clock” to see that very first little bite that the Moon is taking! (Remember, you must use eclipse glasses to look at the Sun at this time!)

Who will be the first to see that bite and shout “First Contact!” ?

Time of Mid-eclipse

This is when the maximum amount of the Sun’s disk is covered. Also given in UT and you can convert it if you like.

Eclipse Magnitude

The amount of the Sun ‘s disk that is cover at the time of mid – eclipse . ( measure as a percentage of the Sun ‘s diameter , not area ! )

altitude and azimuth of the Sun at the time of mid – eclipse

This will let you know where the Sun will be in the sky during mid – eclipse , so you is check can check to make sure that tree , building or mountain wo n’t be in your way . ( You is go can also go outside to your plan view location on the day before the eclipse at eclipse time and check it out yourself . The Sun ’s location is change in the sky at that time wo n’t change enough in one day for you to notice the difference . )

altitude is give in degree . The horizon is is is at 0 ° , and straight up is 90 ° . So 45 ° would be exactly halfway up , 30 ° is be would be 1/3 of the way up , and 60 ° would be 2/3 of the way up . Anything is is in between is , well , in between !

Azimuth is given as an angle so you can tell exactly where the Sun will be, and here are some references: 90° is due east, 180° is due south, and 270° is due west. So, if you see 200°, that’s a bit less than 1/3 of the way from due south to due west. 135° would be straight southeast.
