extraño caso de Supernova
( los datos parecen ok inconsistentes con el débil descubrimiento en abril 2023, con mag. 19 ... ya se verá )

Está situada en el cúmulo de Virgo, (cadena de Markarian), así que "Mitad del verano" entramos en mala epoca para el seguimiento con telescopios terrestres.  Esperemos que puedan desviar la programación de HST o JWST

The discovery of AT 2023fyq (ZTF22abzzvln, PS23fnw) in NGC 4388 was reported to TNS by ZTF on 2023-04-17 and a rapid brightening has been reported by Koichi Itagaki on 2023-07-24. Valerin et al. (NUTS2 collaboration) have reported to TNS the classification of SN 2023fyq as a SN Ib-pec. Here, we report Las Cumbres Observatory global telescope network photometry in the SDSS r and i filters, 30 seconds in each band, calibrated using PanSTARRS DR2, r = 13.16 +/- 0.05 (MJD = 60153.36077) and i = 13.248 +/- 0.05 (MJD = 60153.36154), that confirm the rapid increase in brightness. Additionally, we report ATLAS forced-photometry, available at: https://fallingstar-data.com/forcedphot/queue/598615/ We encourage follow-up photometric and spectroscopic observations. This work makes use of observations from the Las Cumbres Observatory global telescope network

------

K. Itagaki, Yamagata, Japan reports that this object shows a rapid brightening.  On Jul. 23.481 UT, mag abot 13.6.

It is possible that he detects another transient than AT 2023fyq.
