Near Earth Object Survey (MEONEOS)
Also take a look at past years for interesting images and projectsCheck back often as I work on projects in the observatory
MEO Joins the MEERKAT asteroid Guard as an observer to monitor necessary observations for new and potentially hazardous objects that need astrometry as soon as possible to pinpoint an imminent impact or rule impact out with a refined orbit.
Adobe Scan Mar 20, 2024 (7).pdfAdobe Scan Mar 20, 2024 (1) (1).pdfFor my friends not in the NEO community. NEOs are celestial bodies, primarily asteroids and comets, whose orbits bring them close to Earth. My observations play a role in refining the orbital calculations of these NEOs. This refined data is then utilized by astronomers to assess any potential threats these objects might pose to our planet. MEO's contribution directly supports ongoing efforts in planetary defense initiatives. The MPC serves as the central repository for data on minor planets, comets, and other celestial objects. Their work in tracking these objects, calculating their trajectories, and announcing new discoveries is vital for the astronomical community. MEO's role in confirming these discoveries strengthens the overall accuracy and effectiveness of NEO monitoring efforts.
Reaching this milestone represents countless hours of observation, data analysis, and a continuous learning curve. I am committed to continuous improvement, and over the past year, I have implemented significant refinements to my observation procedures and data analysis methods as well as pushing my modest equipment to its best performance.
The opportunity to contribute meaningfully to science and the planetary defense efforts is a significant reward in itself. However, I am also humbled to receive the Gold Award from the Astronomical League in recognition of this achievement. This recognition helps serve as a motivator as I strive to push onward.
MEO remains dedicated to its mission of contributing to the field of NEO observation. I look forward to many more sleepless nights filled with scientific inquiry, and playing a vital role in safeguarding our planet. I like to think of MEO as the little observatory that could!

MEO was successful in contributing observations and astrometry on 2024-05-28 UT to confirm the new Near-Earth object NEOCP ZTs0226 now designated 2024 KP, It is an Apollo class NEO estimated at 28.4 meters in size with an Earth encounter velocity of 12.0481 Kilometers a second. We observed it at magnitude 17.9 moving at 51"/Min. First reported by Observatory (I41) Palomar Mountain--ZTF (N33.357336 W116.859780) US/California.
Next close approach to Earth is 2034-Nov-14.

Have you ever wondered what a typical night of performing imaging and data reduction of minor planets is like? It generally goes like this!
Check the weather and observation conditions.
Open the Observatory, Roll out Instrument trolley and begin instrument cool down.
Power on all the computers and trolley systems.
Update the MPCORB database and star chart database with the latest data. from the Minor Planet Center (MPC).
Select targets of opportunity (TOO's) needed by the MPC to Observe for conformation or orbit improvement. NEO / NEOCP
Confirm GPS time lock and synchronization with all systems. Confirm local sidereal time.
Slew the telescope to a populated star field with no bright stars and perform a multi star FWHM focus.
Slew to the first object and perform a plate solve.
Confirm temperature of the telescope has stabilized and focus is good. confirm camera temperature has reached target temperature.
Perform Calibration frames and set to be applied. Flat frame \ Dark frame.
Estimate TOO rate of movement and magnitude to calculate camera exposure and sub frame needed to capture TOO.
Begin imaging the object over an average twenty minute period or more to capture the necessary three measurements with a minimum of five minutes between each.
Spot-check the first files. Make sure they are correct and are good data.
Perform a data reduction and solve on all images over the capture period.
Check astrometric residuals, format and send measurements to the Minor Planet Center.
Rinse and repeat! Addressing any objects by priority and location in my sky using resources like NEOFixer.
I am very proud to receive a notice from Kelly Fast the program manager of the Near-Earth Objects Observations at the Planetary Defense Coordination Office NASA and IAWN Steering Committee Coordinating Officer that Mind's Eye Observatory (MEO) has been officially accepted as a signatory and member of the International Asteroid Warning Network (IAWN).
The IAWN is an international collaboration, to observe asteroids including Near Earth Objects (NEO), potentially hazardous asteroids (PHA) and provide accurate information about the threat from those objects along with coordinating observation campaigns. The IAWN also is a United Nations-sanctioned organization and helps coordinate communications to assist Governments in the analysis of impact threats and mitigation.
There are approximately 50 facilities in Europe, Asia, South and North America including a few amateur observatories such as MEO with a broad range of expertise.
I am excited to continue producing accurate data for the Minor Planet Center and participate in the IAWN's efforts.

Despite challenging weather and skies, MEO was able to image and measure the position of the newly discovered asteroid A10VCQZ last night 5-28-2023. We imaged it at mag 16.5 and is approximately 72.2 meters in diameter and moving at 12.5 KM a second. Discovered by the Asteroid Terrestrial-impact Last Alert System (ATLAS) in Haleakala Hawaii (T05) on 5-27-2023.
The asteroid is now designated 2023 KT3
Mind's Eye Observatory (MEO) helped confirm a new Asteroid (2023 JF) May 9 UTC. Discovered May 8 UTC unofficially by the Catalina Sky Survey. It was recovered starting in Japan then around the globe by a few observatories. MEO appears to be the first to recover it in the US. Our astrometric observations help extend the arc and update the orbital elements. it has a 0.012% chance of Earth impact or 1 in 8,300 odds of impact. 99.988% chance the asteroid will miss the Earth at this time. With more observations this will likely close up.
It is about 40 feet in diameter and moving at over 4 miles a second so it was fun to keep up with once we found it. Moving this fast it requires very short exposures for accurate measurements while not being very bright. A challenge in itself. When doing astrometry aperture rules! Bigger really is better.
Once large survey telescopes find an object they rely on observatories like MEO to recover and confirm the object as we chase the night shadow around the globe. If not recovered quickly it can be lost because the orbital elements just don't have enough data points to be accurate for recovery. Many objects are lost daily due to this. Location, weather and the moon have an influence on being able to make observations not to mention the need to go to work the next day!
Its great fun chasing rocks in the sky. More importantly, keeping Earth safe through good backyard science!

Torino Scale
The Torino Scale is designed to communicate to the public the risk associated with a future Earth approach by an asteroid or comet. This scale, which has integer values from 0 to 10, takes into consideration the predicted impact energy of the event as well as its likelihood of actually happening (i.e., the event’s impact probability).
Palermo Scale
The Palermo Scale is used by specialists in the field to quantify in more detail the level of concern warranted for a future potential impact possibility. Much of the utility of the Palermo Scale lies in its ability to carefully assess the risk posed by less threatening Torino Scale 0 events, which comprise nearly all of the potential impacts detected to date. Objects are prioritized according to their Palermo Scale values in order to assess the degree to which they should receive additional attention (i.e., observations and analysis). This scale is continuous (both positive and negative values are allowed) and does incorporate the time between the current epoch and the predicted potential impact, as well as the object’s predicted impact energy and likelihood of occurrence.
New-style Provisional Designation Scheme for Objects
- 2016 – the first element indicates the year of discovery.
- E – the first letter indicates the half-month of the object's discovery within that year and ranges from A (first half of January) to Y (second half of December), while the letters I and Z are not used (see table below). The first half is always the 1st through to the 15th of the month, regardless of the numbers of days in the second "half". Thus, E indicates the period from March 1 to 15.[4][5]
- K156 – the second letter and a numerical suffix indicate the order of discovery within that half-month. The first 25 discoveries of the half-month only receive a letter (A to Z) without a suffix, while the letter I is not used (to avoid potential confusions with the digit 1). Because modern techniques typically yield hundreds if not thousands of discoveries per half-month, the subscript number is appended to indicate the number of times that the letters from A to Z have cycled through. The suffix 156 indicates 156 completed cycles (156 cycles × 25 letters = 3900), while K is the 10th position in the current cycle. Thus, K156 stands for the 3910th minor planet discovered in a half-month.
- The packed form of 2016 EK156 is written as K16EF6K.
- During the first half-month of January 2014, the first minor planet identification was assigned the provisional designation 2014 AA. Then the assignment continued to the end of the cycle at 2014 AZ, which was in turn followed by the first identification of the second cycle, 2014 AA1. The assignment in this second cycle continued with 2014 AB1, 2014 AC1, 2014 AD1... until 2014 AZ1, and then was continued with 2014 AA2 the first item in the third cycle. With the beginning of a new half-month on 16 January 2014, the first letter changed to "B", and the series started with 2014 BA.
- An idiosyncrasy of this system is that the second letter is listed before the number, even though the second letter is considered "least-significant". This is in contrast to most of the world's numbering systems. This idiosyncrasy is not seen, however, in the so-called packed form (packed designation).
- A packed designation has no spaces. It may also use letters to codify for the designation's year and subscript number. It is frequently used in online and electronic documents. For example, the provisional designation 2007 TA418 is written as K07Tf8A in the packed form, where "K07" stands for the year 2007, and "f8" for the subscript number 418.
- 90377 Sedna, a large trans-Neptunian object, had the provisional designation 2003 VB12, meaning it was identified in the first half of November 2003 (as indicated by the letter "V"), and that it was the 302nd object identified during that time, as 12 cycles of 25 letters give 300, and the letter "B" is the second position in the current cycle.
- Survey designations do not follow the rules for new-style provisional designations.
- For technical reasons, such as ASCII limitations, the numerical suffix is not always subscripted, but sometimes "flattened out", so that 1989 SG1 can also be written as 1989 SG1.
- A very busy half month was the second half of January 2015 (letter "B"), which saw a total of 14,208 new minor planet identifications as of May 2019. One of the last assignments in this period was 2015 BH568 and corresponds to the 14,208th position in the sequence.[1]

You may notice from these images that they aren't very pretty. Well, they are to some people! Even though they are full of noise the objects of study is there and the data that is needed is there as well. Extra processing of images like these only hurt the raw data so minimal processing is done. These only have a dark frame removed. The timing stamp of the exposure must be very accurate. Mid time is used for the position measurement and comes from a GPS time sync to the imaging computer accurate to within milliseconds.
Carl Hergenrother, OSIRIS-REx Asteroid Astronomy lead, Target Asteroids! co-lead, and Target NEOs! cocoordinator, compiled the original Target Asteroids! list by selecting near-Earth objects that are larger than 200 meters in size and accessible for sample return spacecraft missions. Additional brighter, Main-belt asteroids that are analogues to (101955) Bennu have been added, too.
This list is dynamic and changes as we learn more about these objects and astronomers discover new objects.

Despite the Monsoon season here in Florida Mind's Eye Observatory completes the Minor Planet Centers requirements successfully and receives the IAU Observatory code W42. I will be contributing astrometric measurements to Arc seconds accuracy and photometry to the science community to help refine orbits of solar system bodies. These measurements are sent to the International Astronomical Union Minor Planet Center at the Smithsonian Astrophysical Observatory at Harvard . MEO will also be performing scans of the sky in areas that are not covered well by the large sky surveys looking for new objects.
Asteroid 1433 Geramtina
1433 Geramtina, provisional designation 1937 UC, is a stony Gefion asteroid from the central regions of the asteroid belt, approximately 14 kilometers in diameter. It was discovered by Belgian astronomer Eugène Delporte at the Royal Observatory of Belgium in Uccle on 30 October 1937.
The asteroid was named "Geramtina" after the sister of Swedish astronomer Bror Asplind. Geramtina has an ordinary chondritic composition and has been considered a candidate for being the parent body of the H chondrites. However, results are inconclusive, and recent HCM analysis suggest that Geramtina is a Gefionian interloper rather than a core member of the family. The asteroid has a tentative rotation period of 14 hours.
Data reduction example of asteroid 1433 Geramtina on 2021/10/19 viewed in negative format.
In this image the green circles are stars used in the measurement of the position of 1433 seen at center. The red boxes are last observed positions of asteroids in the image. As you can see the I am unable to reach down to their magnitude at this time. The centroid of the asteroid is found and a measurement from this point and mid exposure time is made. This position is reported to the Minor Planet center for used in refining the orbit and reducing the average residuals.
