M100 Face On Spiral Galaxy 4-28-22

M100 attached is 40 minutes through an IR luminance filter (10X4) and 15 minutes 2x2 binned thru each color filter (RGB )[b] [/b] M100 is one of the brightest galaxies in the Virgo cluster. It is a fine example of the face –on spiral galaxy. It is among the first spirals that have been discovered, and listed by Lord Rosse as one of 14 "spiral nebulae" discovered to 1850. Pierre Méchain re-discovered it on March 15, 1871. Charles Messier added to his catalog on April 13, 1871. It lies approximately 60,000,000 light years from Earth.[b] [/b][b] [/b]Seven supernovae have been identified in M100.[4]· In March 1901 the first was found, SN 1901B,[4][14] a type I supernova found with a magnitude of 15.6 at 110"W and 4"N from its nucleus.· SN 1914A [4][15] was then discovered in February to March 1914; its type was undeterminable but was found with a magnitude of 15.7 at 24"E and 111"S from its nucleus.· Galactic observation from early to mid 1960[b] found SN 1959E, another type I supernova,[4][16] with the faintest magnitude, 17.5, among the five found, at 58"E and 21"S from its nucleus.· On April 15, 1979, the first type II supernova found in the M100 galaxy was discovered; however the star SN 1979C [4][17] faded quickly; later observations from x-ray to radio wavelengths revealed its remnant.· The fifth supernova was discovered February 7, 2006; the star SN 2006X [4][18] had a magnitude of 15.3 when discovered two weeks before fading to magnitude +17.· Supernova SN 2019ehk, discovered on April 29, 2019, reached a peak magnitude of approximately 15.8.· The seventh supernova, SN 2020oi, was discovered on January 7, 2020. It was type Ic supernova, which reached a peak magnitude of 17.7.[4][19]

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
