A warm welcome to all friends of comets and minor planets!
We are living on a beautyful planet, surrounded in space from its large and small
brothers and sisters since unimaginable times.
This web is an independant and ad-free approach to the grand show in our neighborhood in space
with small amateur equipment.
The importance of the amateurs'
collaboration in the follow-up
observations of NEOs is immense
and I am delighted to be part of this global team.
For me as an amateur, participating in the measurement of near-earth bodies is definitely inspiring for my demanding hobby.

Program from July, 11 2020: On this day we have a menu of some comets and a couple of NEOs. The night was very clear with best conditions to observe.
The auto-guided Telescope (LX600) and the camera (St10-XME) are fully automatic controlled by the
programs Orchestrate and TheSky X of Software Bisque over the night session.
The focuser works temperature contolled. So I have nothing else to do as to wait
for the results on the next morning...
Both the following template and the script for Orchestrate are generated by
self-written Free Basic programs.
The preparation time for a night session usually takes 15-30 minutes. The
difference between the calculated observation time of the objects and the real
observation time was 1 minute all night.
Not self-explanatory abbreviations: sq = sequence; Sec = decimal seconds; num = number of exposures; V (on the right) = real Vmag (important for comets); nsg = number of exposures per stacked group; cf = number of stacked groups for measurement; time = local time
All parameters of the template are calculated for my equipment on
location K87 and based on expected
SQM results from Mag/SqArcsec 20 and weaker
with the observation slot.
The selection of comets and partially the V magnitudes of comets are based on the last
measurements of the observers of
CometasObs.

Actual events:
Moon, Mars, Venus, Jupiter and Saturn came together this morning with the beautiful comet C/2020 F3 NEOWISE.
A moment to pause and think about the beauty and size of our universe. This morning made my face smile.

2020-07-12 UT01:38, local time 03:38, 70mm f/3.2, Canon EOS 5D Mark II and
EF70-200mm f/2.8L ISII USM mounted on a tripod, ISO1000, SQM 19.6 mag
Outside temperature: 7° C, elevation: 297m, Processing: Adobe Lightroom. No stiffeners and best distant view.
I left my telescope with its automatic observations and drove a
few kilometers to the highest elevation nearby.
There one of the best moments in my amateur life awaited me with the observation
of an absolute top comet.
The
Apollo
asteroid 2020 KN4 was first observed at
T05 ATLAS-HKO
Haleakala on 2020-05-24.

NEO Apollo 2020 KJ4 was passing the Earth on May, 25 2020 in
0.086249 AU distance ~ 12,902,666 km ~ 80,173,455 miles
The object has a diameter of about 162 meters.
Here you can see a gif animation of this small object:

Comet C/2019 Y4 (ATLAS) is probably starting a desintegration process.
There are two dots westward the central condensation. The comet tail is looking more and more like a cigar.
Here you find a light curve of the comet on CometasObs showing a decrease of the central magnitude since March, 28 2020
In comparison an image of comet C/1999 S4 (LINEAR) during its desintegration process... and one week before
2020 FR3 is an Apollo type asteroid and classified as a PHA.
The small body passed a weak galaxy cluster in the Western edge region of constellation LEO close to the bounder of CANCER
Confirmation of a new comet published on the PCCP on July,22 2018, video of July, 25 2018
The object was published first as object A107IQ9 on the PCCP (Possible Comet Confirmation Page), first detected by T08 ATLAS-MLO, Mauna Loa, Hawaii on July,22 2018
TEST YOUR EYES!
The comet is moving from left to right between the arrows. One loop with arrows, 3 loops without arrows, endless. One loop = 1.25 seconds.
