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 observation of NEOs and comets 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 September, 20 2020:   (~650 measurements of NEOs in September so far)

  That night my gear was dealing with a few NEOs that were mostly spotted in 2020 and one new object from the NEOCP. The whole night was clear  (best SQM result:  MPSAS 21.04 mag).
  There are 21 objects on the list below, not all of them  were captured within approximately 10.1 hours of observation time. Successfully observed: 14 objects.
  C388352 is now the Apollo asteroid 2020 SJ2 (confirmation missed).

  Have a look here for historical informations of K87 --> Hohmann Tranfer Site and NEODyS 

The auto-guiding telescope (LX600) and the ccd-camera (ST10-XME) are fully automatic controlled by the programs Orchestrate and TheSky X Pro of Software Bisque over the night session.
The focuser works temperature contolled. So I have nothing else to do as to wait for the images on the next morning...

Both the following template and the script for Orchestrate are generated by self-written Visual Basic programs on .NET platform.
These programs are actually prepared for global  use for the NEO and comet observing community. The programs are actually in test by K74 Muensterschwarzach.

The preparation time for a night session usually takes 5-15 minutes. The difference between the calculated observation time of the objects and the real observation time was 4 minutes all night.

Not self-explanatory abbreviations:  sq = sequence; Sec = decimal seconds; num = number of exposures; V (on the right)  = "real" Vmag (important both for comets and asteroids, not for NEOCP);
nsg = number of exposures per stacked group; cf = number of stacked groups for measurement; time = local start time of the object. 

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 within the observation slot.
The selection of comets  are  based on the last measurements of the observers of CometasObs.    
The "real" Vmag is the average of the last 10 observations of the objects taken from the MPC observation site.

Actual events:   September, 21 2020 - first night half

Around midnight a bright shooting star of the Southern Piscids crossed Andromeda and Lacerta
and ended its brief light show with a small explosion in the lizard's head... and is this meteor connected with some NEOs? - may be.

Southern Piscid

15sec. exposure, 2020-09-20 UT23:09, local time 01:09, taken with ZWO ASI178MC, 8mm  f/1.4  lens, 1/2.7"; SQM: MPSAS 21.03 mag, NELM 6.1 mag
Elevation: 267m, Processing: Adobe Lightroom and Photoshop. No stiffeners, airplanes or satellites on the image.

The red cross marks the radiant of the Southern Piscids meteor shower, annual maximum: September 20th. Mars is in the lower left.

In this paper by P. B. Babadzhanov - I. P. Williams - G. I. Kokhirova from 2007, the connection between the September Piscids and some Near Earth objects is discussed.


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.

 

I left my telescope with its automatic scanning of the sky and drove a few kilometers to the highest elevation nearby.
There one of the best moments of nighttime observations awaited me.

The object has a diameter of about 65 meters.

Here you can see a gif animation of this small object:

Comet C/2019 Y4 (ATLAS) is probably starting a desintegration process.

C/2019 Y4 (ATLAS) by Bernhard Häusler, K87

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.
