4 measurements spanning 15 days, net +3. Dots are measurements; the straight line between them is drawn to join them, not to claim we know the path taken in between — snapshots are recorded only when a count changes, so gaps mean “no change observed”, never “interpolated”. The vertical axis spans 767–770 and does not start at zero.

ERR is average views per post over the last 30 days divided by subscribers, the definition TGStat uses, so this figure is comparable with the one you will see elsewhere. It falls structurally as a channel grows: a high ERR on a small channel and a low one on a large channel describe reach mathematics, not quality. We publish the figure and the sample it came from and pass no verdict on it.

ER is defined industry-wide as (forwards + reactions + comments) ÷ views— note the denominator is views, not subscribers. Telegram’s public web preview carries views and reactions but not forward or comment counts, so the reaction rate above is the reactions term only and is therefore a floor: the true ER for this channel is higher by an amount we have not measured and will not estimate.

Readings taken8 Aug 2026, 01:49 UTC

Views are a single reading per post, taken at the time above. A post published in the last day or two is still accumulating views, which pulls the 30-day average down slightly. That is a property of the standard definition rather than a fault in it, so we keep the definition rather than “correcting” the number into something nobody can reproduce.

Precision. Telegram publishes view counts on its public widget in short form — 8.12K, 3.7M — so any reading at or above 1,000 reaches us rounded to three significant figures, and only counts below 1,000 are exact. Averages and rates derived from them are shown to the same precision rather than to the unit: a figure like 3,701,250 would assert digits nobody measured.

Reaction counts are published per emoji and rounded the same way, so a total below 1,000 is exact and a larger one is a sum that may carry a rounded component from each emoji above 1,000. Because it is a sum, it does not look rounded — read a large reaction total as three significant figures per contributing emoji rather than as the figure it prints.

Measured directly from 2 videos with a duration reading, out of the posts we hold for this channel — not this channel’s whole posting history, only the sample this register has actually read. An exact reading to the second, taken from the post itself rather than from Telegram’s own rounded chrome, so it carries no mark.

Reaction mix

286 reactions across 20 posts, in 10 distinct kinds. The most used accounts for 71.7% of them.

No sentiment is inferred, and none should be read in. This table is ordered by count and by nothing else. Emoji do not carry stable meaning across languages or communities — 🙏 is thanks in one channel and mourning in another — so we publish which ones were pressed and how often, and pass no judgement on what an audience meant by them.

Precision. Telegram publishes reaction counts per emoji and short-forms each one — 4.34K, 1.2M — so any single kind at or above 1,000 reaches us at three significant figures, and only counts below 1,000 are exact. The shares above are ratios of those figures and carry the same error. This is also why the total here can differ slightly from a reaction total printed elsewhere on the page: both are sums of the same rounded parts, taken over samples with different edges.

Coverage. Reactions were read on 20 of the 20 sampled posts in this sample. Summed by Telegram’s own count on each post — not by adding up the per-emoji breakdown above — those same posts carry 286reactions in total: the kind of figure the paragraph above means by “a reaction total printed elsewhere on the page”.

Measured over the 20 most recent posts we hold, published 5 January 2026 to 4 August 2026, using the newest reading held for each. Telegram Stars are excluded: they are a payment, not a reaction, and they have their own section.

Il cielo del mese di luglio Questo mese puntiamo lo sguardo verso il centro della nostra galassia! Alzando gli occhi verso sud, intorno alla mezzanotte, potrete individuare la direzione in cui si nasconde Sagittarius A*, il buco nero supermassiccio al centro della Via Lattea. La zona, ricchissima di nebulose e ammassi, si trova vicino all'asterismo della Teiera, nel Sagittario. Venere brilla splendida al tramonto e

Equinozio di Primavera Oggi è l'equinozio di primavera. La notte e il giorno avranno durata uguale. Poco dopo il tramonto del sole verso l'orizzonte Ovest, una sottilissima e impercettibile falce di Luna farà da degna compagna a Venere.

Transito di Callisto Poco dopo le 21 di oggi, Callisto transiterà davanti a Giove, ma la sua ombra, in forte ritardo, si inizierà a vedere a partire dalle 2:10 di domani, 27 gennaio, quando Callisto avrà già superato il disco del pianeta. La Luna era al primo quarto questa mattina presto, alle 5:47.

M44, l'ammasso del Presepe M44, nella costellazione del Cancro, in questo periodo inizia a essere ben alto sull’orizzonte. Questo ammasso aperto di circa mille stelle è uno dei più vicini alla Terra, a circa 600 anni luce. Si ritiene che sia piuttosto giovane, con un'età di circa 600-700 milioni di anni. Venne descritto per la prima volta come qualcosa di più di una nebulosa da Galileo, che riuscì a distinguere circ

M1 o nebulosa del Granchio Nel 1054, gli astronomi cinesi notarono una “guest star” che rimase visibile nel cielo diurno per quasi un mese. Si trattava in realtà di una supernova, che diede origine alla Nebulosa del Granchio, un residuo di sei anni luce di diametro di quel violento evento. Con una magnitudine apparente di 8,4 e situata a 6.500 anni luce dalla Terra nella costellazione del Toro, la nebulosa può esser

Showing the 12 most recent of 20 posts we hold for @NotturnoINAF. View and reaction counts are the latest single reading for each post, not a live figure, and a recent post is still accumulating both. A view count marked was rounded by Telegram before we ever saw it — t.me prints views in full below 1,000 and to three significant figures above, so ≈1,200,000 means somewhere between 1,150,000 and 1,249,999. Unmarked counts are exact. Text is reproduced from the public post preview and truncated for length.

Mentions

Names

Channels on the register whose handles appear in this channel's posts.

A mention is a weaker signal than a forward and is counted separately for that reason — naming a channel is not republishing it, and a handle in a post body is easy to place deliberately. The post counts beside each row below are distinct posts in which the handle appeared, from posts we have read on both sides — the “Named by N registered channels” figure above is a different count, of distinct NAMING CHANNELS rather than posts, and is not the sum of the rows under it.
