To observe the <u>[[2023-10-14 Solar Eclipse|Annular Solar Eclipse of 2023-10-14]]</u> in the United States of America (USA), you want to be as far east as possible in order to have the highest possible altitude angle at the time of eclipse maximum.&ensp; However, you also need to be in a location with clear (or mostly clear) skies and no (or very little) wind.&ensp; Corpus Christi (Texas) is the eastern terminus of the eclipse path in the USA but the weather in October for coastal Texas may not be favorable, which means getting further inland.&ensp; The next stop west along the eclipse centerline after Corpus Christi (Texas) is Hobbs (New Mexico).


== list ==
A major difference between a Total Solar Eclipse or Partial Solar Eclipse and an Annular Solar Eclipse is that in order to properly witness Solar annularity, you must be as close as possible to the eclipse centerline and not simply anywhere inside the eclipse path.&ensp; Any deviation from the eclipse centerline will cause Luna to appear off-axis and thus will not form a true Solar annulus.&ensp; Whereas during Solar totality, your geographic position inside the eclipse path determines the duration of totality but does not significantly affect the appearance of totality, unlike during an Annular Solar Eclipse.&ensp; This makes observing an Annular Solar Eclipse much more challenging than a Total Solar Eclipse since the number of available eclipse observation sites decreases in proportion to the square of decreasing distance from the eclipse centerline.

Additional considerations are that you need an unobstructed field of view in the direction of Sol (such as no buildings or trees in the way) and you will get a clearer view if there is vegetation or water in the azimuth direction of Sol (not sand, pavement, or buildings).&ensp; Ideally you want to avoid any urban areas since this can degrade seeing quality.&ensp; Your parking space should also be close enough to the observation site so that you have a direct line of sight between your telescope and your vehicle.

Remember that you should use GPS (Global Positioning System) coordinates to find observing sites and not rely on street addresses, especially since many parks and wilderness areas may have a postal address that is far away from the actual location.


The angular diameter (<var>δ</var>) of a sphere is equal to twice the arcsine of the ratio between the object's radius (<var>r</var>) and the distance to the object (<var>D</var>):

The simplest approximation of the mean distance (<var style="text-decoration: overline;">D</var>) from an observer in a heliocentric orbit to an astronomical object in the same solar system as the observer is as the orbital semimajor axis (<var>a</var>) of the observed object if the observed object is superior or as the orbital semimajor axis of the observer if the observed object is inferior.&ensp; For observers on Terra, the Terran orbital semimajor axis (<var>a</var><sub>🜨</sub>) can be approximated as one [[wikipedia:astronomical unit|astronomical unit]] (<var>l</var><sub>A</sub>).&ensp; For these calculations, satellites in orbit around the observer should be considered as superior objects and satellites not in orbit around the observer should use the satellite's heliocentric semimajor axis.
Latitudes and longitudes were identified using [https://www.googlemaps.com/ Google Maps].&ensp; Elevations are from the USGS (USA Geological Survey) [https://apps.nationalmap.gov/epqs/ Elevation Point Query Service].&ensp; Eclipse start times, times of eclipse maximum, eclipse end times, eclipse magnitudes (mag.), and [[wikipedia:altitude angles|altitude angles]] at maximum eclipse (expressed as [[wikipedia:airmasses|airmasses]] [AM]) are from [https://www.occultations.org/observing/software/occult/ Occult] of the [https://www.occultations.org/ International Occultation Timing Association (IOTA)].&ensp; Average cloudiness (cloud.) for October 14, average windspeed for October (expressed on the [[wikipedia:Beaufort wind force|Beaufort wind force]] [BWF] scale), average air temperature (temp.) for October, and average air pressure (press.) for October are from [https://www.timeanddate.com/ Time and Date Aksjeselskap].

For [[wikipedia:small-angle approximation|small angles]], the mean angular diameter (<var style="text-decoration: overline;">δ</var>) can be approximated as the ratio between the observed object's mean diameter (<var style="text-decoration: overline;">d</var> = 2<var style="text-decoration: overline;">r</var>) and the observed object's mean distance.&ensp; The dimensionless ratio can be expressed in radians (<var>θ</var><sub>I</sub>) without an arcsine:

Revision as of 2023-09-20T10:48:49

To observe the Annular Solar Eclipse of 2023-10-14 in the United States of America (USA), you want to be as far east as possible in order to have the highest possible altitude angle at the time of eclipse maximum.  However, you also need to be in a location with clear (or mostly clear) skies and no (or very little) wind.  Corpus Christi (Texas) is the eastern terminus of the eclipse path in the USA but the weather in October for coastal Texas may not be favorable, which means getting further inland.  The next stop west along the eclipse centerline after Corpus Christi (Texas) is Hobbs (New Mexico).

A major difference between a Total Solar Eclipse or Partial Solar Eclipse and an Annular Solar Eclipse is that in order to properly witness Solar annularity, you must be as close as possible to the eclipse centerline and not simply anywhere inside the eclipse path.  Any deviation from the eclipse centerline will cause Luna to appear off-axis and thus will not form a true Solar annulus.  Whereas during Solar totality, your geographic position inside the eclipse path determines the duration of totality but does not significantly affect the appearance of totality, unlike during an Annular Solar Eclipse.  This makes observing an Annular Solar Eclipse much more challenging than a Total Solar Eclipse since the number of available eclipse observation sites decreases in proportion to the square of decreasing distance from the eclipse centerline.

Additional considerations are that you need an unobstructed field of view in the direction of Sol (such as no buildings or trees in the way) and you will get a clearer view if there is vegetation or water in the azimuth direction of Sol (not sand, pavement, or buildings).  Ideally you want to avoid any urban areas since this can degrade seeing quality.  Your parking space should also be close enough to the observation site so that you have a direct line of sight between your telescope and your vehicle.

Locations listed here should be within 2−16 of a Terran mean circumference (0.6108 kilometers, 0.3795 miles, 668.0 yards, or 2004 feet) from the eclipse centerline which should provide the best possible Solar annulus.

Click here to view the eclipse centerline with Google Maps.

The data provided here is intended as a general guideline only and may contain errors.  These locations were identified based on remote imagery from Google Maps and other than from the information that I can find available on the World Wide Web, I have no idea if they still exist or are publicly accessible.  You should have multiple locations selected in advance, scout the locations in person the day before the eclipse, and allow yourself enough time on the morning of the eclipse to change locations if necessary.

Remember that you should use GPS (Global Positioning System) coordinates to find observing sites and not rely on street addresses, especially since many parks and wilderness areas may have a postal address that is far away from the actual location.

If you think that any locations should be removed from or added to this list, please let me know.  If you have actually visited any of these locations in person, I would love to get any feedback about their accessibility and usability for the Annular Solar Eclipse.

Latitudes and longitudes were identified using Google Maps.  Elevations are from the USGS (USA Geological Survey) Elevation Point Query Service.  Eclipse start times, times of eclipse maximum, eclipse end times, eclipse magnitudes (mag.), and altitude angles at maximum eclipse (expressed as airmasses [AM]) are from Occult of the International Occultation Timing Association (IOTA).  Average cloudiness (cloud.) for October 14, average windspeed for October (expressed on the Beaufort wind force [BWF] scale), average air temperature (temp.) for October, and average air pressure (press.) for October are from Time and Date Aksjeselskap.
