New discoveries from Santa Maria de Montmagastrell Survey

Weißt du wieviel Sternlein stehen an dem blauen Himmelszelt?
                                     Spain sucks, so Catalonia wants to be independent

Total asteroids discovered from MPC B74 : 279
Total asteroids discovered from les Planes de Son (MPC C29) : 13
Total asteroids discovered from Teide Observatory (MPC 954) = 3
All discoveries from B74 + C29 + 954 = 295

Our asteroid 266983 (2010 WE66) is named Josepbosch in honor of my son Josep Bosch Olivera. Also 322390 (2011 QN42) is named Planes de Son and 367693 (2010 RZ109) is named Montmagastrell.

This site has discovered two NEA Aplollo class: 2009 ST19 (see below) and 2012 UT9.

Asteroid NEO Apophis, January 12, 2013.
The stars are elongated beacause the apparent motion of the asteroid relative to the stars was tracked during the exposure.

Follow-up Astrometry
This site (B74) has sent 7319 total observations until July 2014. Follow-up astrometry and recoveries are made with the Advanced Coma-Free optical system like the Ritchey-Chrétien 16 inch f/10 Schmidt-Cassegrain at Santa Maria de Montmagastrell Survey (IAU code B74). The  CCD has 24 micron pixels and a 21'x21' field. At the moment, the telescope pointing control are computer controlled from the above control room. The dome is sliding roof type and it slides off of the top of the roof onto supports.

Data Reduction
All data are reduced on a PC. Flat-fielding is done using MaxIm DL. The astrometry is done with both TheSky6 Astronomy Software and Herbert Raab's Astrometrica which has an excellent track and stack option. As Astrometrica also allows the simple identification of all objects in the field, this is currently the software of choice.
Following the release of UCAC-4, virtually all of our astrometry is done using this. An astrometric accuracy in the fit of 0".0 – 0”.5 RMS in each coordinate is obtained for several hundred stars within the field. For high S/N targets, the absolute accuracy of the astrometry is of about the same magnitude; the absolute accuracy of UCAC-4 being smaller than this.

Astrometric results of NEOs observed from Santa Maria de Montmagastrell Observatory can be found listed on the NEODYS B74 page. Contributions from Santa Maria de Montmagastrell Observatory have been published in the IAU Circulars and in the Minor Planet Center's Electronic Circulars:

My first discoveries, in 2009

Asteroid 2009 YW6 (333744)

The Minor Planet Center (MPC) has assigned on December 21, 2009 a new discovery. The asteroid 2009 YW6 (333744) was discovered in images taken on December 20 and confirmed by Antonio Garrigós (MPC B37) and the author in new observations the night after. I will ask for the asteroid 333744 the name Pau Bosch in honor of my grandson Pau Bosch Pellicer, born in 2007.

Discovery of the Apollo PHA asteroid 2009 ST19

This minor planet, belonging to the Apollo class, is also flagged as a "Potentially Hazardous Asteroid (PHA)", an object that, because of its orbital parameters, might represent a possible threat of impact for planet Earth (http://neo.jpl.nasa.gov/neo/pha.html).

It has beeen discovered by the Spanish amateur astronomer Josep M. Bosch from Santa Maria de Montmagastrell (MPC B74) on 2009, Sept. 16.2, ay magnitude about 17. At that time it was posted on the NEOCP webpage of the Minor Planet Center as "jmbo11"; after a couple of days it was withdrawn, because it was not confirmed by any further observations.
On 2009, Sept. 22, the LINEAR sky survey picked-up a fast moving object, that was posted in the NEO-Cp as "BQ24981". After some follow-up observations from various sites, on 2009 Sept. 23 the MPC published M.P.E.C. 2009-S72 (http://tinyurl.com/yer5xmr), informing that the two objects mentioned before were actually the same celestial body.
According to the NEODyS webpage this object. about 1.5 Km in diameter, made a close pass to Earth on 1980, Oct. 4, at a minimum possible distance of about 0.009 AU (nominal distance of about 0.04 AU).

Observatory Santa Maria On September 23th, at 10:00 pm. I went on a motorcycle to my observatory, located in a small village of 60 inhabitants called Santa Maria de Montmagastrell, 8 km far from my house. As I walked out of the fuel station, my mobile phone started to rang. At the time, I stopped the bike and went back to the side of the road, the phone stopped calling. Upon arrival at the observatory, the call repeated while preparing the telescope for another observation night. This time, I can answer the call phone. It was Gustavo Muller to communicate that they had just numbering the possible NEO I saw in some pictures taken last September 16. That past day, I had gotten up at three in the morning and, among other objectives, Comet 137p looked to no avail. Well, the comet was not in the 14 pictures I took of the field and so I went to other objectives that had to watch. At dawn, with the first light was fading I control systems and the telescope placed in sleep mode to close the observatory and go to bed to rest. At that time, I reviewed the images of the comet 137p field by the custom of not leaving any possibility loose. I started the blink of images and in less than a second I realized that there in the fourteen shots 70 seconds each moving something big. I checked that was not a known object, and then I sent four astrometric measurements to the MPC. Hours passed, spent six days, and when he had lost hope of recovering the object the MPC announced it had been found by various observatories, including the LINEAR and gave the 2009 provisional number ST19. I thought I had lost, although the night I had a discovery following email exchange with Tim Spahr of the MPC, who assured me find it. And they've found!

Richard Miles said:
Yes, Special congratulations, José María. This is a very special object. It breaks the record in terms of the closest pass by an object of this size, about 1 km across! 
We currently know of no object larger than this to have come closer than this object has recently. The next largest such object was the famous (69230) Hermes (H=17.5), which approached to 0.0050 AU of the Earth in 1937! Your PHA, 2009 ST19 will be visible during the next few weeks and so will be a good target for photometry.

My preferred reading is the medieval catalan literature           For example:

Book chapter 305 from the Llibre dels feits de Jaume I
E, en aquell temps que nós estàvem a Montpesller, venc-nos aquí lo comte de Tolosa, e el comte de Proença, e haguem grans corts d'hòmens honrats d'aquelles terres que ens venien veer. E açò fo un any aprés la presó de València. E entram en Montpesller el dijous: e el divendres, entre mig jorn e hora nona, fo eclipsis major que anc hom vis de memòria d'aquells hòmens que ara són, car tot lo Sol cobrí la Lluna, e podia hom veer bé set esteles en lo cel. E, ab aitant, quan nós haguem bé feites nostres fazendes en Montpesller, a bé e honrament de nós, faem armar lo bus de Montpesller qui era de vuitanta rems e venguem-nos en tro a Cotlliure; e per terra venguem-nos puis a València.
