An amateur astronomer: Ethan Chappel from Cibolo, Texas, US observed a bolide impact with Jupiter. The approximate time of the impact was 2019-08-07 04:07 UTC. Ethan captured his video on the red channel with a C8, Chroma Red filter and ASI 290MM. The image on the right was produced by the DeTecT software that uses differential photometry images of a video to look for possible impacts in the planet.
Congratulations to Ethan on this discovery.
Observers from the American continent observing the planet at the same time may have got also a video observation of the same impact. If anyone has a second detection it would help to constrain the size and mass of the object, specially if the second detection was made with a different filter. The flash seems too small at present to have caused an impact scar. The flash was recorded at approximate coordinates: 10.0º (System III) and -19.0 (Pg). This is about 60 deg west of Jupiter's GRS. A search on images acquired over the next minutes/hours of the same region might be worthy. An impact scar is unlikely though.

Observations over the last couple of years have shown discrete events of red material flowing apart from the GRS. This activity has increased over 2019 and recent observations obtained by several amateurs including notable images by A. Wesley and C. Foster show "flakes" outside of the GRS and a distorted shape.
Observations on May 22 show a very distorted GRS in blue and methane band filters that indicate an intensification of this recent activity. The images on the right were obtained by Anthony Wesley.
Observations are requested to monitor this activity. Red, Blue and methane band filters are required to investigate the nature of the behavior of the GRS. Frequent observations are needed as the activity is evolving on a daily basis. Ephemeris of the GRS transits on the Central Meridian of the planet can be found here

Marc Delcroix has released a new version of the DeTeCt software to find look for impacts in video observations of Jupiter and Saturn. The new software can be downloaded from its github page or from the jovian impacts section in PVOL.2018-10-28
Recent observations by Blake Estes acquired on 22 October 2018 using the 60'' Mount Wilson telescope show a bright cloud feature at the border of the bright polar hood. This storm has now been observed by other amateur astronomers and is visible in some observations obtained with large telescopes.WinJUPOS 10.3.11 (Uranus), C.M. transit times, 2018/11/14 10:06 Object longitude: L = 270,0° - 24,7470°/d * (T - 2018 Oct 09,5) Output format: Date UT (C.M. of System 1) ------------------------------------------------------------------------------ 2018 Nov 01 12:48 ( 60°) 2018 Nov 02 05:14 ( 43°) 21:39 ( 26°) 2018 Nov 03 14:05 ( 9°) 2018 Nov 04 06:31 ( 352°) 22:57 ( 335°) 2018 Nov 05 15:22 ( 318°) 2018 Nov 06 07:48 ( 301°) 2018 Nov 07 00:14 ( 285°) 16:40 ( 268°) 2018 Nov 08 09:05 ( 250°) 2018 Nov 09 01:31 ( 234°) 17:57 ( 217°) 2018 Nov 10 10:23 ( 200°) 2018 Nov 11 19:14 ( 166°) 2018 Nov 12 11:40 ( 149°) 2018 Nov 13 04:06 ( 132°) 20:32 ( 115°) 2018 Nov 14 12:57 ( 98°) 2018 Nov 15 05:23 ( 81°) 21:49 ( 64°) 2018 Nov 16 14:15 ( 47°) 2018 Nov 17 23:06 ( 13°) 2018 Nov 18 15:32 ( 356°) 2018 Nov 19 07:58 ( 340°) 2018 Nov 20 00:24 ( 323°) 16:49 ( 306°) 2018 Nov 21 09:15 ( 289°) 2018 Nov 22 01:41 ( 272°) 18:07 ( 255°) 2018 Nov 23 10:33 ( 238°) 2018 Nov 24 02:58 ( 221°) 19:24 ( 204°) 2018 Nov 25 11:50 ( 187°) 2018 Nov 26 04:16 ( 170°) 2018 Nov 27 13:07 ( 136°) 2018 Nov 28 05:33 ( 119°) 21:59 ( 102°) 2018 Nov 29 14:25 ( 86°) 2018 Nov 30 06:50 ( 68°) 23:16 ( 51°) 2018 Dec 01 15:42 ( 35°) 2018 Dec 02 08:08 ( 18°) 2018 Dec 03 00:34 ( 1°) 16:59 ( 344°) 2018 Dec 04 09:25 ( 327°) 2018 Dec 05 01:51 ( 310°) 18:17 ( 293°) 2018 Dec 06 10:43 ( 276°) 2018 Dec 07 03:08 ( 259°) 19:34 ( 242°) 2018 Dec 08 12:00 ( 225°) 2018 Dec 09 04:26 ( 208°) 20:52 ( 191°) 2018 Dec 10 13:17 ( 174°) 2018 Dec 11 05:43 ( 157°) 22:09 ( 140°) 2018 Dec 12 14:35 ( 124°) 2018 Dec 13 07:01 ( 107°) 2018 Dec 14 15:52 ( 73°) 2018 Dec 15 08:18 ( 56°) 2018 Dec 16 00:44 ( 39°) 17:10 ( 22°) 2018 Dec 17 09:36 ( 5°) 2018 Dec 18 02:01 ( 348°) 18:27 ( 331°) 2018 Dec 19 10:53 ( 314°) 2018 Dec 20 03:19 ( 297°) 19:45 ( 280°) 2018 Dec 21 12:10 ( 263°) 2018 Dec 22 04:36 ( 246°) 21:02 ( 229°) 2018 Dec 23 13:28 ( 213°) 2018 Dec 24 05:54 ( 196°) 22:19 ( 178°) 2018 Dec 25 14:45 ( 162°) 2018 Dec 26 07:11 ( 145°) 23:37 ( 128°) 2018 Dec 27 16:03 ( 111°) 2018 Dec 29 00:54 ( 77°) 17:20 ( 60°) 2018 Dec 30 09:46 ( 43°) 2018 Dec 31 02:12 ( 26°) 18:38 ( 9°) 2019 Jan 01 11:03 ( 352°) 2019 Jan 02 03:29 ( 335°) 19:55 ( 318°) 2019 Jan 03 12:21 ( 301°) 2019 Jan 04 04:47 ( 285°) 2019 Jan 05 13:38 ( 250°) 2019 Jan 06 06:04 ( 234°) 22:30 ( 217°) 2019 Jan 07 14:56 ( 200°) 2019 Jan 08 07:22 ( 183°) 23:47 ( 166°) 2019 Jan 09 16:13 ( 149°) 2019 Jan 10 08:39 ( 132°) 2019 Jan 11 01:05 ( 115°) 17:31 ( 98°) 2019 Jan 12 09:56 ( 81°) 2019 Jan 13 02:22 ( 64°) 18:48 ( 47°) 2019 Jan 14 11:14 ( 30°) 2019 Jan 15 03:40 ( 13°) 2019 Jan 16 12:31 ( 339°) 2019 Jan 17 04:57 ( 323°) 21:23 ( 306°) 2019 Jan 18 13:49 ( 289°) 2019 Jan 19 06:15 ( 272°) 22:40 ( 255°) 2019 Jan 20 15:06 ( 238°) 2019 Jan 21 07:32 ( 221°) 23:58 ( 204°) 2019 Jan 22 16:24 ( 187°) 2019 Jan 23 08:49 ( 170°) 2019 Jan 24 01:15 ( 153°) 17:41 ( 136°) 2019 Jan 25 10:07 ( 119°) 2019 Jan 26 02:33 ( 102°) 2019 Jan 27 11:24 ( 68°) 2019 Jan 28 03:50 ( 51°) 20:16 ( 35°) 2019 Jan 29 12:42 ( 18°) 2019 Jan 30 05:08 ( 1°) 21:33 ( 344°) 2019 Jan 31 13:59 ( 327°) ------------------------------------------------------------------------------Links:

Mars is getting closer to its opposition in July just at the right time in its dusty season. After several detections of regional dust storms in the planet a global storm in Mars is on its development stage. Images by J. Rueck, D. Milika and P. Nicholas and D. Peach among other observers show the onset of this new large-scale storm. Orbiters around Mars are following the extension and growth of the current storm. A report from the MARCI instrument on the MRO mission is available here.
The image on the right compiled by Agustin Sanchez Lavega shows a comparison of amateur observations with data
from the MARCI instrument on Mars Recoinnassance Orbiter.
We encourage all observers to image this Mars dust storm. The five most recent planetary storms detected in Mars occurred in 1977, 1982, 1994, 2001 and 2007. Typical global storms on Mars can develop and lasts over time-scales of a month or longer.

Saturn continues to display interesting atmospheric activity to the reach of amateur equipment. An equatorial bright storm with two sides and located at planetographic latitude +6.0 has been observed by several observers since February and notably over April. The feature is probably the same equatorial bright feature observed since 2014 and has been object of recent scientific research(Sanchez-Lavega et al., Nature Communications, 2016).Here are ephemeris of its transits over Saturn's CM using System I. Note that besides the prominent Equatorial and polar storms some other repeated features are observed also in the planet at latitudes +20 to +60.

Maciel Bassani Sparrengerger has imaged a bright spot on Saturn CM on March 29 at 08:16:05 UT that has later been confirmed by several observers.http://alpo-j.asahikawa-med.ac.jp/kk18/s180329z.htm
Updated ephemeris of this feature based on images from 29 March to 22 April are given below as calculated by Marc Delcroix. Urgent observations are required at all longitudes to follow the storm evolution, and search for other possible spots.

A convective outbreak in the South Temperate Belt has started in the region previously covered by the STB Ghost and following oval BA. Observations by Anthony Wesley and Damian Peach show the initial stages of this storm on February 4. Additional images by Jim Phillips indicate the activity probably started around February 2.2017-11-08
Updated on 2017-12-04Amateur observations of an equatorial bright large cloud in Neptune since June-July and over October and November have allowed to folow different cloud systems over the planet. Equatorial features followed by amateur astronomers in this period includ the close interaction of two equatorial clouds in November 6-10 and what appears to be a chain of equatorial clouds visible afterwards.
Many amateurs now (most notably Phil Miles, Darryl Milika and Pat Nicholas) have observed these cloud systems repeteadly providing very useful data to study this unusual equatorial cloud activity in the planet.
Updated ephemeris of the bright equatorial cloud are given below and have been calculated by Marc Delcroix.

The Cassini mission: Imaging Sub-System (ISS), Composite Infrared Spectrometer (CIRS) and Visible-Near Infrared Mapping Spectrometer (VIMS) will be getting very high-resolution observations soon (2017 April 26) during the spacecraft’s initial “dive” between the planet and the inner rings. The ISS images will have a very restricted coverage of the atmosphere, so observations from the Earth are being solicited by Dr. Linda Spilker, Cassini Chief Scientist and the different instrument teams. Best times for observations will be ffrom UTC 07:48:11 to 12:22:11 but any close in time observations will be very useful.Message sent by Dr. Glenn S. Orton (JPL/NASA) on behalf of Dr. Linda Spilker (Cassini Chief Scientist).
